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. |

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 E ........
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.
