El Plomo Section
El Plomo is considered to hold promise for the discovery of a Broken Hill Type ("BHT") silver-lead-zinc deposit. BHT Geological data suggest s that the genesis of the silver-lead-zinc mineralization at El Plomo is similar to the BHT silver-lead-zinc deposits.
Dr. Spry, an expert on BHT deposits, has outlined over 20 geological similarities between El Plomo and classic BHT deposits around the world.
In 2019, the Company conducted an airborne magnetic and electromagnetic geophysical survey over the Dawson-Green Mountain property because known BHT deposits are characterized by positive magnetic signatures. The survey successfully discovered a subtle but distinct 2.5 km long magnetic anomaly located approximately coincident with and south of the mineralized trend.
The survey results and subsequent 3D modelling has yielded targets worthy of drill testing, in particular the West Anomaly, which is the target of the current drill program in progress. The West Anomaly sits immediately below drill holes GC-8 and GC-9 and may reflect the down dip extension of silver-lead-zinc mineralization intersected in these holes. See news releases April 16, May 5 and June 17, 2020 for additional information.
Historic Drill holes GC-8 & GC-9
*GC-8 intercepted 1.9% zinc over 5.6 m (52.1 to 57.8 m) whereas GC-9, located closer to the magnetic anomaly, intercepted 5.3% zinc over 8.2 m (55.6 m to 63.8 m).
