Work History

Staked as HAO cl 1-289 by Equity Resources in 2011 and optioned to Habanero Resources.

Alianza Minerals Ltd. entered a purchase agreement in 2018 to purchase the HAO claims from Equity. In 2018, they carried out rock and soil geochemistry on the claims leading to the discovery of the Bighorn occurrence. In 2019, they completed diamond drilling of one hole (351 m), prospecting, trenching and bedrock mapping at the Bighorn occurrence.

Regional & Property Geology

The Mt. Haldane area is underlain by the early Carboniferous Keno Hill quartzite. The quartzite overlies mid to late Devonian Earn Group quartz- and feldspar-phyric chloritic phyllite metavolcanics (Roots, 1997). Carbonaceous Earn Group phyllite and siltstone underlie the metavocanics. A large regional thrust fault, the Robert Service Thrust, is present in the area, which puts Keno Hill quartzite into thrust contact with Proterozoic Hyland group phyllite and schist. Numerous Triassic age metadiorite sills intrude both the Keno Hill quartzite and Earn Group rocks located around the occurrence. Several small Cretaceous age granitic dykes and intrusions also intrude the sequence (AR 097320).

Mineralization & Results

The Bighorn occurrence is marked by a 900 m by 150 m, north-south trending Pb-Ag-Sn soil anomaly, Mapping and trenching in 2019 indicated the anomaly is associated with north-south striking faults and/or silicified breccia zones in lower Keno Hill Formation quartzite and phyllite. Mineralization consists of
siderite-quartz-galena-sphalerite veins and/or breccia fillings (Alianza Minerals Ltd., News Release, 22 Oct/2019).

Drilling in 2019 intersected mineralization associated with faulting of gossanous, sheared and brecciated phyllitic quartzite with up to 3% galena. Hole HLD19-15 intersected 6.6 m of 50.1 g/t Ag, 1.85% Pb, 0.09% Zn, and 0.004 g/t Au over 6.6 m, including 4.39% Pb and 125/7 g/t Ag over 2.35 m (Alianza Minerals Ltd., News Release, 22 Oct/2019).
