OPERATIONS: - Phase I Development (Pilot Plant) already built in 2015/16. Gravity only processing plant, open pit mine. - Mix of dry (truck-excavator) and wet mining (Marok pumping). - The Company currently operates the plant at lower volumes on selected days, to collect information for Large Scale Mining and PFS: A) operating costs & testing of dif. mining methods, B) metallurgical test work. - Gold ounces sold ease corporate cash calls. |

The Eagle Mountain PL is held by the Company’s 100%-owned subsidiary in Guyana, Stronghold Guyana Inc.
Summary:
The main and most significant style of gold mineralization on the Eagle Mountain Property is related to a series of tabular, shallow southwest-dipping, brittle-ductile composite shear zones within the granodiorite intrusion. This mineralization style forms the Eagle Mountain mineral resource. Very fine-grained gold is associated with chloritic ± pyritic micro-fractures and in some cases within or adjacent to discrete chlorite – pyrite ± potassic altered mylonitic shear zones. Alteration and sulphide mineralization within the mylonitic structures is interpreted to be syn-deformational.
A second style of mineralization is present west of the Eagle Mountain mineral resource where molybdenum mineralization occurs within the folded stratigraphy west of the Minnehaha fault in the Dispute Pit area. The felsic rocks within the fold package are the principal host, where mineralization occurs in association with epidote-sericite alteration. Molybdenite occurs as disseminated grains within the rock matrix, in quartz veins, particularly at vein margins, and within fractures. Mineralized quartz vein stockworks are developed within the centre of strongly altered units. Minor molybdenite is also present throughout the meta-volcanic and metasediments, occurring within quartz veins or coating fractures. Molybdenum and gold have an inverse grade relationship, and are interpreted to have occurred as two spatially and/or temporally separate events. Trace molybdenum occurs within the Eagle granitoid at quartz vein margins in association with areas of epidote/chlorite alteration.
The Eagle Mountain gold deposit and probably the Dispute pit area mineralization best fit into the orogenic lode gold deposit clan. Orogenic gold deposits (Moritz, 2000) are present in metamorphic terranes of various ages, displaying variable degrees of deformation. The host geological environments include volcano-plutonic and clastic sedimentary terranes. The host rocks have been characteristically metamorphosed up to greenschist facies conditions, and locally to amphibolite or granulite facies conditions. The gold deposits typically occur within or in the vicinity of regional, crustal-scale deformation zones with a brittle to ductile type of deformation. The geologic structures generally indicate compressional to transpressional tectonic settings. The gold deposits can be hosted by any rock type.
Summary:
The Eagle Mountain saprolite deposits vary in dip (15 to 25 degrees) and thickness (5 to 40m) along strike and at depth. As a result, conventional mechanised mining methods have been selected. The development of the mining method and consequent equipment selection is based on owner-operated excavating, bulldozing, and loading into an in-pit mobile processing plant.
Flow Sheet:
Summary:
The mineralized material from the open cut resources will be processed by state-of-art conventional gravity recovery technology. Coarse materials from screening will be stockpiled with potential milling and further gold recovery in the future. Tailings will be considered valuable and will be collected and retained (settling pond) for potential further processing in the future.
The Sepro Saprolite plant utilizes gravity concentration as its primary gold recovery process. The plant includes unit operations for washing of laterite and saprolite clays, sizing the material, concentrating the free gold and upgrading the concentrate to a potentially smeltable product. In the current plan, various mineralized oversize fractions will be stockpiled for future processing. The concentrator tails will be de-watered using a cyclone and stockpiled for future processing as well.
The ROM material will be fed onto a grizzly by a wheel-loader or excavator. A water monitor will be ........
