The Lochinvar VMS deposit is located approximately 200 m northeast from the former Hammerdown Gold Mine.
Two steeply plunging, massive sulphide lenses have been traced from surface to approximately 200 m depth where they remain open, though there are indications that they will be truncated at depth along the late Captain Nemo Fault.
The mineralization is partially delineated over a strike length of 700 m and remains open to the northeast.
The mineralization consists of heavily disseminated to massive sphalerite, galena, chalcopyrite, and pyrite with lesser barite and significant tennantite and electrum.
It occurs within a steeply-dipping, strongly sericitized, carbonatized and locally chloritized, soda-depleted (0.2% Na2O), schistose felsic volcanic package up to 75 m thick.
The altered felsic package is separated from an underlying undeformed mafic volcaniclastic unit by the “Captain Nemo Fault” and is overlain by a unit of aphyric, green andesite/dacite fragmental rocks.
Drilling in 2020 intersected a thick zone of mineralization with 0.85 gpt Au, 150.9 gpt Ag, 0.73% Cu, 3.33% Pb and 7.62% Zn over 11.6 m including 0.74 gpt Au, 210.7 gpt Ag, 2.03% Cu, 10.64% Pb and 23.83% Zn over 2.5 m in drill hole GA-20-25.
