Brownfield Exploration Program
The brownfield exploration program, which commenced in 2018, has incorporated multiple modern exploration techniques, many used for the first time at the Project, and targeted only a small portion (9km2) of the total Project area (175km2). This area was selected due to its high prospectively as it hosts two known high-grade VMS deposits (Winston Lake and Pick Lake), whilst only limited historical exploration has been completed.
This program has included the following.
- Structural and lithogeochemical program – seven targets identified
- Drill program and DHTEM – Pick Lake deposit
- High powered, FLTEM geophysics program testing identified and unknown targets.
To date, this program has been a success with the first drill program in more than 20 years delivering a 10% increase to the size of the resource (2.35 Mt at 17.7 %Zn, 0.9% Cu).
Following the drill program, a Down the Hole Transient Electromagnetics (“DHTEM”) program was completed at Pick Lake. As Pick Lake is a known deposit, this was simply a “test case” to confirm EM could successful identify the deposit. The results were positive as Pick Lake was clearly identified.
Following the structural and lithogeochemical program, the Company commenced a Fixed Loop Electromagnetics (“FLTEM”) program, incorporating 5 transmitting loops over a 3km x3km area using state of the art transmitter and sensor technology. From this program three mineralised anomalies have been identified as highlighted in Image 1 below.
