SUMMARY The organisational structure of the Commission caters for the Mines Division and the Geological Services Division assuming responsibility for the execution of the majority of the functions of the Commission. The Legal Division, the AdministrativeDivision and the Finance Division provide support forthe Mines Division andthe Geological Services Division, as well as directly executing some of the Commission's functions. This review is structured so that the responsibilities of the respective divisions are evident. The Commission played a major role in the mining sector of Guyanaduring 1990. Mining Engineers and Mines Officers, with responsibility for the administration of the Mining Act and Regulations, visited all the commercial mining operations, and reported on all aspects of their operations. Reports are on file forthe following operations: Licence Holder Mineral GUYMINE Bauxite Linden " " Kwakawani Aroaima Mining Co. " Aroaima Permit Licence Holder Mineral/Ore Tootsie Persaud Ltd Stone (crushed) St. Mary's Essequibo Baracara Quarries Ltd Stone (boulders) Monkey Jump, Essequibo GNS Stone (boulders) and Crushed Teperu, Mazaruni Small Miners Gold All mining districts Small Miners Diamonds " " Various Operations/Ceramin Sand Soesdyke Ceramin Kaolin ltuni 0. Atkinson Amethyst Aishalton The prevailing fiscal and legislative regime for gold, diamonds, sands, kaolin, and semi precious stones (amethyst, agate, etc) resulted in significantly increased declaration and lawful explorationof those mineral commodities. Certainly, the record gold declaration indicates that the Guyana Geology and Mines Commission and small miners are doing things right together. Especially hearteningwas thatnon-traditional minerals such as kaolin, silica sandand amethystare finding their way to overseas markets. Agates, jasper andpegmatite (feldspar) also have markets overseas available and it is hoped thatorders can be filledduring 1991. The Guyana Geology and Mines Commission also obtained approximately five tons of soapstone fromKauramembu area at the request of the Creative Arts Departmentof the University of Guyana. Local sculptors are utilising it, andthe GGMC re-commenced research into theuse of soapstone forpaint manufacture. In additipn, researchinto the production of black sandsconcentrate (to obtain titanium minerals) as a by-product of dredging was continued. 1 The Guyana Geology and Mines Commission successfully negotiated Agreementsfor several more properties to be licensed forexploration and mining ofgold and diamonds, with one company showing interest in shell deposits and another in stone. The exploration highlight of the year was the filing by Cambior/GSR Ltd. of a feasibility study for the mining of the gold deposit at OMAI. Mazda Ltd. began development work on their gold placer deposit in the Konawaruk valley. Production at a rate of20,000 ozs per annum, is scheduled forMay, 1991. Several local small miners, on the advice of the GGMC, introduced banka drilling to delineate their placer gold deposits before mining. Pereira's Nine Mile gold mine introduced exploratory diamond drilling with the help of the GGMC. Sample analyses for several of these programmeswere done by the laboratories of GGMC. Foreign companies used geology, geochemistry, geophysics and remote sensing as their major exploration technique. Ofparticular interest to theGGMC was theairborne magnetic surveys conducted by Questar on behalf of Golden Star Resources Ltd and Denison Mines Ltd. The latest in computer processing techniques were applied in evaluating the results of the surveys with excellent results. It is now clear to explorationists thataeromagnetics can be successfullyapplied in thesearch formineral deposits in our environment. The GGMC opened discussions with Denison and GSR in relation to having the north of Guyana covered by airborne magnetics using the latest computerized processing techniques. It appears that CIDA and UNDTCD may be interested in funding such a project. The exploration activity highlighted the need for the GGMC to upgrade its Cartographic, Library (maps, books and periodicals, sample storage areas, and core drilling capability). The GGMC's Library is a major repository of information on mineral deposits in Guyana and each foreigncompany has researchers at work in our libraryon a regular basis. This work by researchers brought into sharp focusthe importance of upgrading our facilitiesto minimise deterioration of our maps and books. Maintenance and extension ofthe facilities commenced in 1990 and will continue in 1991 with suggested computerisation of systems, and air-conditioning forthe area where rare and single copy volumes are stored. Computerised draftingis now installed. Dension Mines Ltd. Homestake Minerals, and Golden Star Resources Ltd used
