Exploration (circa 1940) at Echo-Indin included surface sampling and diamond drilling. Drilling targeted quartz stock-works in gold mineralized shear zones that extend for several hundred metres in metavolcanic rocks. Merc's 2011 field activities focused on locating historical drill setups, surface trenches, and confirming (and extending) reported gold mineralized shear zones.
Showings up to 1.5 kilometres north of Echo-Indin at Goose Lake and Lucky Lake appear to represent the extension of the Echo-Indin mineralized shear zone. Known gold occurrences are within a 1.0 metre to 8.0 metre wide shear zone containing quartz-carbonate veins and veinlets with pyrrhotite, arsenopyrite, stibnite, and pyrite within silicified basalts. Cross-fractures of flat lying quartz veins were also noted.
Highlights of surface sampling at Echo-Indin include three assays greater than 30.0 g/t Au, thirteen assays greater than 4.0 g/t Au, and twenty-two assays greater than 1.0 g/t Au.
