“ Achievement of plans and milestones in 2022
The principal activities of the Company in the six months ended June 30, 2022 have been:
Technical efforts for the 1st half of 2022 have focused heavily on compiling the requisite data, studies and designs in support of the Feasibility Study on La India Open Pit.
Key activities for the first 6 months were:
• Review of La India Project’s regional discovery potential with twenty-two exploration targets identified.
• Completion of the La India deposit resource model, resulting in an upcoming revision of the Mineral Resource Estimate and Mineral Reserve Estimate (MRE), incorporating the newest drilling results, new structural, weathering, mineralogical and lithological interpretations, as well as updated depletion models of artisanal mining impacts
• Review of mining methods employed for selective open pit mining, and incorporation of the selective mining units to a diluted mining model suitable for mine planning
• Finalization of the geotechnical model reflecting drilling and testwork during 2021, based upon new oriented core and televiewer logging.
• Multiple scenarios on plant throughput and recovery from 52 micron to 100 micron grind size, and potential processing plant modifications
• Completion and costing of processing and support infrastructure optimized to take advantage of the compete new Semi-autogenous (SAG) mill package, including:
o An updated design from Hanlon / GRES engineering to process up to 886,000 tpd through the plant with an upgraded 3.7 MW motor, with 48 hours of retention capacity for the Carbon-in-Pulp (CIP) plant
o The tailings storage facility costing for the initial construction lift
o Surface water management structures, including diversion channels, attenuation
structures and stormwater pumping
o Surface infrastructure for Administration, Warehouses, Plant and mine support, and a revised supervisor man-camp.
o Access roads for the mine, waste dumps, stockpiles, and construction sites
-9-
o Commitments from the local energy provider for power supply and specifications for connection to the national grid
• Updated contractor quotes for mining, reagents and consumables, explosives, and contractor- provided facilities
• Site staff generated cost estimates for the owner’s obligations and additional staffing requirements for EPCM controls on the owner’s side.
• Conducted third party reviews of critical FS Study inputs, for Geotechnical analysis for pit angles and Metallurgy
• Updated and revised mine plans to provide stormwater management through the pit area, with optimized stockpiling strategies, ultimate pit designs and phase plans, in conformance with the recommendations from the SRK geotechnical analysis
•
