Work History
Staked as Rainbow cl (12705) in August 1918 by L. Beauvette, who dug a few hand pits. Re-staked in May 1949 as Happy Day cl (59219) by M.H. Ewing, and in July 1956 by E. Hager as Vancouver, etc cl (62985), which was explored by S. Arbutina with hand pitting and 18.9 m of drifting by 1960. W.T. Synott tied on the Rake and Nova cl (Y14848) in May-November 1968.
Re-staked as Sundown cl 1-12 (Y56107) in August 1970 by C. Klippert. In 1978, the Cortin Project (Billiton Canada Ltd., CCH Resources Ltd., Inco Ltd.) performed a brief mapping and sampling program under an option.
Re-staked as McCoy cl 1-4 (YC01061) by F. Anderson in May 1998. Anderson staked Hatfield cl 1-6 (YC01075) later in the month.
Re-staked as Black cl 1-163 (YC02090) in November 1999 by Expatriate Resources Ltd., which carried out geological mapping, prospecting and soil sampling in 2000.
Re-staked and consolidated as Haldane cl 1-99 by Equity Exploration Consultants Ltd. who optioned the claims to Habanero Resources Inc. in 2010. Habanero carried out soil sampling at Sundown in 2011.
Alianza Minerals Ltd. entered a purchase agreement in 2018 with Equity for the Haldane claims. In 2018, they carried out bedrock mapping and soil geochemistry at the Sundown occurrence. Prospecting was carried out in 2019.
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).
Geological mapping completed by Expatriate shows that this occurrence is centred on a 3.5 to 4 m wide quartz porphyry dyke that cuts muscovite-chlorite phyllite assigned to the Yusezyu Formation of the Upper Proterozoic Hyland Group. The trace of the Robert Service Thrust lies 1 km to the north (AR 094179).
Mineralization & Results
The Sundown showing is located on the southern portion of the Mt. Haldane vein system. It is centered on a 4 m wide porphyry dyke that is strongly chloritized and sericitized and cut by tourmalinized veinlets. The dyke is mineralized with disseminated arsenopyrite (AR 095930).
The best grab samples from the Sundown occurrence taken in 1977 and 1978 assayed 58.0 ppm Ag and 0.3% Pb with 3 ppm W and 19 ppm Sn. Soil samples nearby range up to 2.8 ppm Ag with low values in other metals (AR 090931).
Expatriate examined the dyke and collected three samples in 2000. All three returned low gold values but a 1.40 m chip sample across the east side of the dyke that included a 1.5 cm wide quartz-chlorite vein returned 402.0 g/t Ag and 0.12% Pb. Soil sampling indicated a north trending Pb-Zn-Sb-Ag anomaly open to the north (AR 094179).
