Natural resources, particularly the mineral
resources are the hidden treasures of a country. Minerals are used in different
purposes for the benefit and comfort of the human kind as a simple stone axes
in those Stone Age and as Jewelry, cosmetics, electronic equipments, nuclear
medicine etc. in this developing world of 21 century. Proper exploitation and
utilization of valuable mineral resources present in the country and promotion
of mineral industries based on our own minerals and export of finished quality
products definitely help to develop infrastructures, generate income/
employment to the people, reduction in dependency on foreign imports and save
foreign currency. All these results ultimately help in poverty reduction, which
is the ultimate national goal of 10th Five Year Plan of the country
(Nepal ).
Every individual mineral resource is finite and nonrenewable in nature and
therefore exhaustible on exploitation. That is why proper mining and
sustainable development of mineral resources without any environmental
degradation is the present policy of the government. For the sustainable
development of the mineral resources in Nepal, the Department of Mines and
Geology/ Ministry of Industry, Commerce and Supplies, HMG Nepal has made some
significant changes in it’s policy, strategy, management practices, mining rule
and regulations and petroleum laws to attract the private entrepreneurs in
mineral sector as well as international oil companies to invest in exploration
and development of petroleum in Nepal. Keeping this view the Department has
designed 4 priority projects as (1) Geological survey and research (2) Mineral
exploration and development (3)
Operation of seismological centers and (4) Petroleum exploration, promotion
project. All of them are in the process of implementation in ongoing 10th
Five Year Plan period (2002/2003 – 2006/2007). All the activities of each
project are prioritized by adopting Medium Term Expenditure Framework (MTEF) approach in project planning and
budgeting. If the present crisis in the country is resolved and the situation
comes to the normal then there are many opportunities to implement the projects
activities that are related to mineral resources development and also promote
the mineral based industries in Nepal .
As a result, mineral sector can provide substantial contributions in the
national economy (GDP), which will finally contribute to reduce the poverty
level (from 38 to 30%) as envisaged in the 10th Five Year Plan.
2. DEPARTMENT OF MINES AND GEOLOGY
Department of Mines and Geology (DMG) is the sole
government organization, which is quite similar to the Geological Survey of
other countries in its status, objective and most of the activities. It is
under the Ministry of Industry, Commerce and Supplies.
2.1OBJECTIVE
The main objectives of the
Department of Mines and Geology are:
- To conduct all types of geological investigations and research,
mineral resources exploration, development, promotion of mineral based
industries and administration of mining rules and regulations.
- To provide the basic geo-scientific information and expert services
to mineral exploration and development entrepreneurs, institutions and
individuals involved in infrastructure development planning, mitigation of
natural hazards and environment protection
through research and investigations.
- To manage the government investment in mineral exploration and
development and promote mineral based industries sector through formulation of
sound mineral policy and legislation ultimately to uplift national economy.
- To regulate and monitor the mineral exploration, mining and mineral
based industries and ensure that mineral development activities are carried out
in compliance with the government’s mineral policy and related laws (rules and regulations).
- To advise the government on
matters related to mineral development and geological hazards.
2.2
ORGANIZATIONAL STRUCTURE
At present the Department of Mines and Geology (DMG)
has 232 technical and nontechnical staffs in total. It is exercising its duties
and responsibilities through 3 Divisions, 4 Sub divisions, 25 Sections and 1
independent project all under the Director General. All these Divisions,
Sub-Divisions and Sections are actively involved to achieve the objective/
goals of the Department (Fig.1).
2.3
MAJOR ACTIVITIES AND OUTCOME
The main activities (mission)
of the Department of Mines and Geology are (1) Geoscientific survey and
research (2) Engineering and environmental geological studies/ Hazard mapping
(3) Mineral exploration, evaluation and promotion of mineral industries (4)
Exploration petroleum and natural gas (5) Seismic studies and earthquake
monitoring (6) Administration of mining rules and regulations (7) Move from the
traditional geological works to more scientific way, for sustainable
development and look for alterative source of energy and minerals particularly
renewable energy resource (8) Carry out researches and development of
appropriate technology for optimum use of natural resources for the benefit of
the people in the 21st century.
Till this time, DMG has conducted regional
geological mapping and published geological maps covering whole Nepal in
1:1,000,000scale; Sub Himalaya and Lesser Himalaya in 1:250,000 scale and most
part of Sub-Himalaya, Lesser Himalaya and small part of Higher Himalaya in
1:50,000 and 1:63360scale. At present DMG is conducting geological mapping of
new areas as well as updating of previously prepared geological maps and
regularly publishing these geological map sheets (in scale 1:50,000). The
department is also engaged in engineering and environmental geological mapping
of urban areas (in 1:15,000 and 1: 50,000 scale) and hazard mapping of some
selected areas. National Seismological center is engaged in seismotectonic
studies and earthquake monitoring to delineate high earthquake hazard prone
areas. All these maps are used as base maps for mineral exploration and
development planning, regional/ local infrastructure development planning, land
use planning, disaster mitigation and environment protection.
In Nepal , small scales metal mining
has been historically exploited for copper, iron, nickel and cobalt. In those
days Nepal used to export
these commodities to Tibet
and India .
However, proper geoscientific investigation was started only in sixties and
systematic geological mapping and exploration of metallic minerals like copper,
lead, zinc, nickel, cobalt, molybdenum, tin, tungsten, uranium, gold, silver
etc. as well as nonmetallic minerals like limestone, dolomite, magnesite,
marble, phosphorite, talc, slate, clay, salt, (brine water), kyanite, calcite,
mica, quartz, gemstones etc. and fuel minerals like coal, natural gas and
petroleum was started in seventies. Mineral exploration with the assistance of
UNDP was also undertaken mostly for base metals during 1970 - 1972 and 1975 -
1980 and for gold exploration during 1987-1991.
Such activities in the past in the Lesser Himalayan
region were able to discover a number of economic and sub-economic mineral
deposits/ prospects/ occurrences/ showings and natural gas seeps in Muktinath in Mustang
district and natural gas as well as oil seeps in Padukasthan, Sirsasthan and
Navisthan in Dailekh district. Similarly 316 million cubic meter of methane gas
is discovered in Kathmandu
Valley (Fig.2). Among all
these discoveries most of the metallic mineral deposits are found either small
in size or low in grade to categorize them as economic deposits. Those
deposits, which are categorized as economic, also remained unexploited because
of their size of deposit, difficult terrain, lack of infrastructures and
investors. However, Nepal
has a number of commercially viable nonmetallic mineral deposits like
limestone, dolomite, marble, magnesite, talc etc. mostly close to the road
heads. Potentials for finding economic gold, gemstones (ruby, sapphire,
tourmaline, aquamarine, garnet etc.) and petroleum is fairly high in the
country but exploration of these valuable commodities has not yet been carried
out in that extent to confirm their economic status.
Based on the economic deposits
few mines and mineral industries such as cement, marble, magnesite, talc, coal,
salt, gemstone, red clay, kyanite, quartzt etc. are in operation (Table.1). The
commercially viable mineral commodities (Table.2) and production of some of the
mineral industries/ mines are presented in table.1. At present, HMG Nepal has
implemented new Mines and Minerals Act, 1985 as well as supplementary Mines and
Mineral Rules, 1999. Under these rules and regulations DMG has issued 53 active
mining licenses and 67 prospecting licenses to the investors in FY 2002/2003. A
license holder must pay the surface rental of the lease area and royalty
depending upon the type of mineral commodity and the amount/ volume of
production as per the rules and regulations. DMG keeps up to date records of
leaseholder and annual production of different mineral commodities. The
government has given authority to District Development Committees (DDCs) to
issue licenses and collect revenues only for exploitation/ mining of river
boulders, gravel and sand as simple construction raw materials.
DMG/ Petroleum Exploration
Promotion Project (PEPP) is engaged to promote petroleum exploration and
development in the country since 1982. By 1990 it was able to identify 10
prospective blocks in promising southern Terai plain and Siwalik foothill. Each
prospective block is nearly 5000km2. Composite data package with
geological and seismic data of the individual blocks are available to the
potential investors for exploration bidding. International oil companies are
invited to conduct exploration and development of petroleum in the above
promising areas. In 1986 -1990 Shell Company explored block 10 in detail but
could not trace oil or natural gas. Since last 3 years Texana Resources Company
of USA
has initiated exploration activities in Block no3 (Nepalgunj) and Block no.5
(Chitwan). Recently Cairn Energy PLC, UK has submitted a bid proposal to
explore in other 5 prospecting blocks (no.1, 2, 4, 6 and 7). Evaluation of its
proposal by the evaluation committee has been completed. However, decision has
yet to be made by the government. Data sale packages relevant to petroleum
exploration are available from DMG/ PEPP.
Similarly natural gas exploration in Kathmandu valley was able to discover 316 million m3
of natural gas (methane) deposit in 26km2 area. Based on this deposit DMG has
invited potential investors to bid for the development and commercialization of
the gas resources.
National Seismological Centers in Kathmandu
and Birendra Nagar are operating 21 short period telemetric stations. Both
centers are continuously operating and monitoring the earthquakes. All these
data are helpful to delineate the earthquake hazard/ risk areas. The center
also allows a quick seismic surveillance
2.4 NATIONAL GOAL
In 10th Five Year Plan the
National Planning Commission, HMG/ Nepal has set the National Goal as
“Poverty Reduction” from 38 to 30% levels.
2.5 SECTORAL GOAL
The Sectoral Goal of Mining
Sector is the sustainable development of mineral resources and promotes mineral
based industries in the country.
3. GOVERNMENT POLICY FOR MINERAL DEVELOPMENT
HMG Nepal is committed to
sustainable development of the mineral and petroleum resources available in the
country. To meet the above objectives it has developed some policy guidelines,
strategies and also made some changes in management practices.
3.1 POLICIES AND STRATEGIES
HMG Nepal has promulgated a
new Industrial Policy 1992 and foreign investment and one window policy 1992.
Permission for foreign investment is allowed up to 100%, in large and medium
scale industries. It has also outlined
the policies and spell out the management practices for mineral resources
development.
·
Develop mineral resources in the country for
conveniences and economic welfare of the public as well as for speedy economic
development of the country.
·
DMG acts as the primary policy-provider,
administrative facilitators and provider of basic geological infrastructure
service supplied to the private sector to promote mineral industries sector.
·
Due priority will be given to the exploration
and mining of the construction materials and other nonmetallic minerals without
any environmental degradation, can provide quick economic return and
fulfillment the present internal demand.
·
Priority will be given to attract the public
private entrepreneurs and international investors in exploration and
development of mineral resources and international oil companies to invest in
petroleum exploration and promotion.
·
Efforts will be made for integrated planning of
geoscientific researches and implement them systematically.
·
Steps
will be taken to expand, improve, upgrade and efficient operation of National
Seismological center. Seismic hazard assessment will be made based on workout
parameters
·
Necessary legislation will be provided to ensure
that mineral development activities are carried out in an environment friendly
manner in compliance with the mineral laws:
* Mines and Mineral Act, 1985 with first Amendment
1993 and Mines and Mineral Regulation 1999 with first amendment 2003.
* Nepal Petroleum Act, 1983, Petroleum Regulation 1985
with first Amendment 1989 and second Amendment,1994 and Petroleum Industry
(Income Tax) Regulation, 1985 and amendment in 1995.
3.2 EXPECTED MAIN OUTPUTS AND SERVICES
To reach the goal of the 10th
Five Year Plan, meet its purpose and expected outputs some activities are
planned to conduct within 5 years time. For this logical framework for each
project is prepared during the planning process. The main estimated outputs are
prepared according to MTEF approach. Similarly key programs and activities
(prioritized and ranked) of all 3 different projects for 10th Five
year Plan (FY2002/2003 to 2pp6/2007) are presented in table.3.
3.3 PROGRAMMING AND BUDGETING
MTEF is a new technique/
approach to prioritize the project. It helps to utilize limited resources for
the selection of a best project. According to the MTEF concept the projects are
prioritized on the basis of (a) contribution to national goal (b) sectoral goals
(c) contribution to regional balance (d) role of government (e) participation
by the people/ local government /public enterprises (f) project status and (g)
certainty of funding. DMG has adopted MTEF approach while preparing the 10th
Five Year Plan in project planning and budgeting. For this a Policy Matrix,
Logical Framework was prepared for each project. To implement all the
activities to complete the project in time an Immediate Action Plan and
Calendar of Operations are prepared and implemented in the department since the
last fiscal year.
3.3.1 PROGRAMS SET FOR 10th FIVE YEARS PLAN PERIOD
According to the instructions
given by the National Planning Commission (NPC) the programs were designed and budget was estimated for Running cost,
Overhead cost and Objective costs for 10th Five Year Plan and made compatible
with MTEF.
In mineral sector, 10th Five
Year Plan has given priority in the following programs and activities.
·
Exploration and evaluation of huge limestone
resources to promote cement industries, which helps to meet the internal
demands, save foreign currency and provide quick economic return.
·
Priority is also given to the exploration and
development of high price metals like gold and precious stones prospects so as
to get immediate return.
·
Petroleum exploration is another priority
project of Department of Mines and Geology.
·
Fast growing urban areas in the country as well
as neighboring India and Bangladesh have
very high demand of construction materials, dimension stones either as the polished
slab or in other forms. Therefore, emphasis is given in the investigation of
construction materials and dimension stones to develop quarries and promote
stones industries and also use river boulders, gravel and sand as main sources
of construction aggregate for the civil works.
·
Priority is also given for regular monitoring of
mines ands quarries to control pollution, regularize mineral production and pay
the right amount of royalty to the government.
·
Another priority is the publication of all types
of geological maps, engineering and environmental geological studies of urban
areas, hazard mapping, and constant recording and monitoring of earthquakes in
Seismological centers for quick seismic surveillance.
3.3.2 BUDGETING
After the
discussions at various level among National Planning Commission, Ministry of
Finance and Line Ministry the projects and their activities/ programs are
finalizes. Then the Government convinces the donor for resource allocation.
Budget is totally controlled by the Ministry of Finance. It releases
development budget to implement activities as recommended by the National
Planning Commission. In this current FY 2003/2004 there is no increment in the
total budget because of budget sealing. As a result some of the proposed programs/
activities comparatively on least priority were dropped. However, in the
following years extensive works are proposed to meet the targets set for 10th
Five Year Plan. Therefore more development budget is demanded for priority
project activities. Development budget are mainly allocated in 3 heads (1)
Personal cost (2) Running cost and Development cost.
3.4 ARRANGEMENTS FOR EFFECTIVE IMPLEMENTATION,
MONITORING AND ACCOUNTABILITY
All the
field programs/ activities of each project are designed with a view to conduct
smoothly to meet the anticipated targets defined in Annual and Five Year Plan.
MTEF is used to bridge the gape between Annual plan and Five Year Plan.
Regular
supervision of all the field activities and laboratory works by the project
Chief, Director General/ Deputy Director General are in practice in
coordination with the In-Charge/ Section Chief. In site guidelines are provided
to the working staffs.
Preliminary
results/ outcome of each activity are presented in in-house seminar/ talk
program and discussed for further follow up or detail investigation. Field
In-Charge must submit a preliminary report within 35 days after completion of
his field works and a final technical report with findings on due date.
Review and
mid term evaluation of the project activities is done annually as guided by
MTEF in presence of field In-charge, Section Chief, Project Chief, Chief of
Planning Section and Director General.
Regular
monitoring of mines and quarries operated under the license issued by DMG is
carried out by the Mining Regulations and Administration Division/ DMG to
control haphazard mining and consequence pollution. Higher management
authorities carry out verifications of monitoring plans.
Private
sectors are encouraged for exploration and mining of economic mineral resources
and invest more in mineral based industries and international oil companies are
invited to invest in petroleum exploration and development in Nepal .
Researches
are also concentrated on seismotectonic and data obtained by constant recording
and monitoring of all earthquake events in the country. Information's are
shared with other similar international organizations. Further efforts will be
made for mid term prediction of recurrence time of earthquake with compilation
of seismic hazard maps.
Preparation
of database and networking through Internet with various agencies and mining
companies and international oil companies are in progress.
Regular
production of Annual reports, field reports, publication of DMG Newsletters,
DMG Pre'cis, information booklets and geological, geo-environmental and Seismic
hazard maps and their circulation to the various organizations / potential
users are the parts of its regular activities.
4. GENERAL GEOLOGY AND MINERAL POTENTIAL
(A)
The Terai (Indogangatic
Plain)
The Terai represents the alluvial plain located
towards southern most part of the Kingdom. The sedimentary deposits of this
plain belong to the last phase of the Himalayan upheaval and conceal beneath
them are the northern fringe of Peninsular India and the southern fringe of the
Himalaya . This area comprises of few hundred
to over 1000m thick Quaternary sediment deposits that consist of gravel,
pebbles, sands, silt and clay with some remains of organic materials. This area
is the potential area for ground water, oil, and natural gas. Detail
exploration for petroleum by DMG and international companies is in progress.
Construction materials like Boulders, gravel and sand can be extracted/ mined
from the riverbeds of this area.

Sub-Himalaya (Churia Range /
Siwalik Hills): This part of the Himalaya is bounded
by Main Fontal Thrust (MFT) to
the south and by Main Boundary Thrust
(MBT) to the north. The MFT, in most places is concealed below the
colluvial debris derived from the Siwalik Foothills and Gangetic alluvium. Sub Himalaya comprises of largely fluviatile more than 6km
thick sequence of molasses type sediments represented by sandstone, siltstone,
mudstone, shale and conglomerate deposits of Mid-Miocene to Early Pleistocene
age. As in India and Pakistan the rocks of the Siwalik Group of Nepal are also
divided (a) Lower Siwalik (b) Middle
Siwalik and (c) Upper Siwalik Formations. Few coal lenses and small radioactive bodies are recorded in
Siwalik sandstone. There is a possibility of existence of suitable reservoirs
and seal rocks for petroleum and natural gas. Construction materials like river
boulders, gravel, pebbles and sand are mined from the Rivers. In some places
sandstone blocks are exploited and used for flooring etc.
(C)
The Lesser Himalaya : It is confined within Main
Boundary Thrust (MBT) in the south and Main Central Thrust (MCT) to the north.
It is 60 to 100km wide and comprises of a thick succession of largely
unfossiliferous metasedimentary rock of Pre-Cambrian age and crystalline nappe
intruded by a number of granite bodies of Ordovician Age. This region is fairly
complicated due to the presence of numerous folds, faults and thrust sheet
structures. The main rock types encountered in the Lesser Himalaya are
limestone, dolomite, quartzite, shale, sandstone, slate, phyllite, quartzite,
schist, gneiss, granite, pegmatite and amphibolite. This part of the Himalaya is potential for metallic minerals like Iron,
Copper, Lead, Zinc, Nickel, Cobalt, Tin, Tungsten, Silver and Gold
mineralization/ occurrences. Similarly Nonmetallic/ Industrial minerals like
limestone, dolomite, magnesite, phosphorite, marble and fuel minerals like
coal, natural gas are potential sources. Small scale copper, lead/ zinc mines,
coal/ lignite mines, limestone, magnesite, talc, slates, and marble quarries
are in operation in this part of the Himalaya .
(D)
The Higher Himalaya :
It is bounded to the south by Main Central Thrust (MCT)
and to the north by Tethyan sedimentary sequence. This part of the Himalaya
comprises of high grade metamorphic rocks like garnet mica schist, kyanite/
sillimanite garnet mica schist, quartzofelspathic schist, amphibolite, gneiss,
quartzite, marble of Pre-Cambrian age and leucogranites of Tertiary age. It is
believed that the Higher Himalaya is the root zone of the crystalline nappe. A
number of lead and zinc occurrences/ deposits are recorded in the crystalline
carbonate rocks and ruby, kyanite, garnet and sillimanite in calcareous schist.
Tin, tungsten and uranium are prospective in granitic terrains. Some of the
pegmatites are prospective for gemstones like tourmaline, aquamarine/ beryl and
garnet.
(E)
The Inner Himalaya
(Tibetan Tethys Zone): It is bounded to the north by Tsangpo Suture Zone and to the south by
Higher Himalayan Crystalline rocks. The rocks of this zone are represented by
sandstone, limestone and shale. These rocks are fairly rich in invertebrate
fossils of Late Paleozoic to early Cenozoic age. This part of Nepal Himalaya
appears to be prospective for natural gas and petroleum.
5. FUTURE MINERAL EXPLORATION PLAN AND INVESTMENT OPPORTUNITIES
In Nepal the mineral based industries
are few but they are contributing about 3.8% in GDP. Currently the main
contributors in this field are (a) Udayapur Cement Industries Ltd. (b) Hetaunda
Cement Industries Ltd. (c) Godavari Marble Industries Pvt. Ltd. (d) Coal/
lignite industries (e) Magnesite and talc industries (f) Construction material
mining industries (g) Gem mineral industries (h) stone and red clay quarries
(i) few industrial mineral mines etc. Investment opportunities are available in
Nepal
in the mineral exploration and promotion of the mineral based industries
(table-2).
·
Present domestic cement production fulfills only
about 30 - 40% of the current demand. The Mahabharat Range
(Lesser Himalaya) in the country provides potential target areas for
exploration of the cement grade as well as chemical grade limestone. About
1,000,000,000 tons limestone deposits are already identified in this area.. The
limestone deposits of Chaukune (Surkhet), Gandari (Dang), Katari-Galtar
(Udayapur), Narpani (Arghakhanchi), Nigale (Dhankuta) and Kazeri (Sallyan) are
quite promising for the establishment of he cement and allied industries. Some
more promising limestone deposits are under exploration in Udayapur, Baitadi,
Syangja, Dang, Rolpa, Palpa etc. The government is giving high priority to
explore these limestone resources in near future to promote cement industries
to fulfill the internal demand and if excess to export. Therefore, there is a
very good opportunity for the investors to invest in the promotion of these
limestone deposits and establish cement factories in Nepal . The high chemical grade
limestone also has good market in the subcontinent.
·
In Lesser Himalaya there is a huge potentiality
of dolomite deposits (over 1,000,000,000 tons) in Nepal . Department of Mines and
Geology has already prepared a proposal on "Industrial utilization of
dolomite resources of Nepal "
and submitted to the National Planning Commission and Line Ministry to request
to the government of South
Korea for Technical and Financial helps.
Investment to conduct extensive exploration and development of these huge
dolomite resources from private / public investors are awaited.
·
The country has a high demand of dimension
stones either as the polished slab or in other forms. The Godavari marble
industry is partially fulfilling the domestic demand but most of them are
fulfilled from the external supplies mainly from India . Everest Marble is in trial
production. Investigation of dimension stones in Sindhuli, Kavre, Lalitpur,
Makwanpur and Dhadhig districts by DMG is in progress with a view to identify
the potential target areas for development and promote stones industries. A
project proposal for "investigation and preparation of Master plan for
construction material resources in Nepal " has been submitted to
NPC to get technical and financial help from the Chinese government.
·
The river boulder, gravel, and sand in Terai
plain and Churia Range are also considered as the major
source for production of construction aggregate for the civil works. Evaluation
of these assets has roughly proved about 550,000,000 m3 construction materials.
Since there is a great demand for such materials in Kathmandu, Pokhara,
Biratnagar and other fast growing urban areas in Nepal as well as in India and
Bangladesh the Department of Mines and Geology has already started further
economic to evaluation of these resources and also look for the best place for
stone quarries close to the road head to meet the internal demands as well as
export to neighboring countries. There is a good prospect of investment in this
field.
·
Gem quality ruby, sapphire, tourmaline,
aquamarine, garnet, kyanite and quartz crystals reveal high potential in the
country. They need a proper assessment. DMG is planning to conduct exploration
of gemstone in this 10th plan period. The promotion of gem industries is likely
to be highly rewarding. Many of the potential areas are sill remain unexplored.
·
Petroleum exploration provides another area of
considerable promise for investment in Nepal . Presently eight blocks of
nearly 5000 sq. km areas each are available for exploration by local or
international oil companies. Recent discovery of oil showings in some of the
wells drilled in India
situated close to Nepal
border is an positive evidence towards encouragement in undertaking petroleum
exploration activities in Nepal .
DMG/ Petroleum Exploration Promotion Project is inviting more international oil
companies to invest in petroleum exploration and development in Nepal .
·
Potential target areas for gold exploration are
found in different parts of the country. Alluvial gold is traced in most of the
major rivers coming from the Higher Himalayan regions. Such indications of
alluvial gold of which primary sources still remain unidentified. However,
recent discovery of in-situ primary gold sources in Rolpa, Baitadi and Darchula
regions are the encouraging indications for prospecting gold in many potential
areas of Nepal .
DMG has given high priority to conduct further exploration and evaluation of
this precious metal.
·
Lead Zinc deposits in Ganesh Himal area is
another mineral wealth, which can be mined economically. It needs further
investment to construct a zinc concentrate plant and further exploration of
other deposits located in this region. Government is looking for potential
investor to exploit this hidden treasure.
Beside these mineral deposits
there are a number of small to medium size sub economic copper, lead/ zinc,
polymetal sulphide, tungsten, phosphorite, quartzite, garnet, kyanite, mica,
graphite, kaoline etc. deposits in different parts of the country. Indeed there
is a need of further detail exploration to confirm these deposits as economic.
6. CONCLUSIONS AND
RECOMENDATION
Difficulties has been arising
in mining administration due to contradiction in some of the Rules in Mines and
Mineral Act 1985, with First Amendment, 1993, Forest Act, 1992 and Local Self
Governance Act 1998 and rules and regulations, 1999, that needs immediate
clarifications and some amendment if required in these Acts.
There is no regional and district office of DMG to
provide necessary services to the local lease holders. Establishment of
district level offices in priority basis is necessary especially for mines
administration.
.
Substantial budget is
required to run all the field programs in full swing and to provide basic
facilities, field equipments to the staff, to strengthen and regular operation
and maintenance of all the geoscience laboratories.
Favorable working
environment in the field must be prevailed to conduct all types of field
activities within time frame. Otherwise it is almost impossible to conduct
field activities in the remote areas.
Mineral exploration, evaluation
of the deposit and promotion of mineral based industry is a 5 to 12 years long
process. Laboratory facilities to analyze all types of samples also depend upon
its reliability, capacity and volume of samples. Therefore, strengthening of
existing Geoscience labs is highly recommended.
Exploration and
identification of some potential target areas for precious metals, precious/
semi precious stones, polished/ dimension stones and promotion of mineral
industries based on the local raw minerals must get priority at the earliest to
be sufficient at least in internal demand, if more to export.
Commercialization of Kathmandu Valley Natural gas
not only helps to substitute the gas import in the valley but also save foreign
currency. Therefore commercialization of this resource must get priority.
Because of lack of basic
infrastructures (road, electricity, water supply etc) in the deposit sites and
less incentive private companies are reluctant to invest in the mines and
mineral industries. In this competitive world of 21st century, more
incentive has to be provided to the investors to invest in mineral sector.
Government must try hard to
attract international oil companies to invest in petroleum exploration and
promotion by providing basic geological information and seismic data and
offering competitive terms and condition of petroleum agreement.
There should be peace in the
country and substantial increase in development budget so that defined targets
for 10th Five Year plan cold meet and economic mineral deposit are
proved to promote more mineral based industries in the country.
