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 suggests that the genesis of the silver-lead-zinc mineralization at El Plomo is similar to the BHT silver-lead-zinc deposits.
Dr. Spry, a world class expert on BHT deposits, has outlined over 20 geological similarities between El Plomo and classic BHT deposits around the world.
Broken Hill was the largest base metal deposit ever discovered at over 250 million tonnes of high grade ore.
Cannington was a blind deposit discovered through gahnite geochemistry and a magnetic survey in 1990 It's size was over 40 million tonnes of high grade ore.
All of this results in El Plomo being a particularly exciting drill target for 2020. It is anticipated that drill testing will commence in July 2020 subject to funding and equipment availability.
In 2019 the company conducted an airborne magnetic and electromagnetic geophysical survey over the Dawson-Green Mountain property. BHT deposits can be highly magnetic while the surrounding rocks typically have a low magnetic susceptibility. This magnetic contrast can make these surveys an effective method for exploration of this deposit type.
3D inversion modelling on the airborne magnetic anomaly at El Plomo demonstrates that the historic drilling (GC-8 & GC-9)* failed to intercept the strongest magnetic signature. From core magnetic susceptibility analysis, management is confident that the sulphide metal content is correlative to magnetic strength. This in turn suggests that higher grade mineralization may be present at depth.
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).
