Work History
Silver-lead mineralization was probably found on Mt Haldane prior to 1906 and was staked as Lookout, etc cl (2332) in March 1915 by A. Johnson and J.V. Smith.
Re-staked by E. Bleiler and M. Ewing in October 1944 as Middlecoff cl (55320),which was optioned in 1952 to Lookout Mountain Mines Ltd., and in 1964 to Silver Titan Mines Ltd., which added DB, May, Ted, etc. cl (83403) in May 1964 and conducted geochemical sampling, bulldozer trenching and adit rehabilitation. The Haldane main zone was discovered about 457 m north of the Johnson zone between 1964 and 1965.
The property was transferred to Haldane Silver Mines Ltd. in 1966. In 1968, Paramount Mining Ltd. acquired control of Haldane Silver Mines Ltd.
Re-staked as Middlecoff, etc cl (YA1913) in April 1967 by M.H. Ewing and optioned in 1978 by Barry Way, who added Gopher, etc cl (YA17722) in April and performed grid soil sampling in 1978-1979.
The property was examined briefly in 1978 by Cortin Project (Billiton Canada Ltd., CCH Resources Ltd., Inco Ltd.). Ewing optioned the property to Barandium Resources Ltd. Barandium changed its name to IGC International Golf Corporation in March 1990. The claims were returned to Ewing in February 1991.
Re-staked as Black cl 1-163 (YC02090) in November 1999 by Expatriate Resources Ltd. which carried out soil sampling and a cursory examination of the veins in 2000.
Re-staked and consolidated as Haldane cl 1-99 by Equity Exploration Consultants Ltd. in 2008 who carried out rock geochemistry and bedrock mapping. Equity optioned the claims to Habanero Resources Inc. in 2010 who carried out prospecting and bedrock mapping. Habanero carried out diamond drilling (1 hole, 306 m), prospecting, bedrock mapping and soil geochemistry in 2011 and further diamond drilling (2 holes, 125.3 m) in 2013.
Alianza Minerals Ltd. entered a purchase agreement in 2018 with Equity for the Haldane claims. Alianza carried out rock and soil geochemistry and bedrock mapping in 2018.
In 2020, Alianza drilled 4 holes for 798.6 m, 2 holes in the Mt Haldane target and 2 in the Middlecoff target.
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 Mt. Haldane vein system contains three main mineralized zones, named from north to south, Middlecoff (MINFILE occurrence 105M 149), Johnson (MINFILE occurrence 105M 148), and Haldane zones. All three zones appear to be part of a single, north-trending, transverse type vein fault with many branches, which cuts the Mississippian aged, Keno Hill quartzite. The vein faults are located in the footwall of the Robert Service Thrust and are believed to cut the thrust and continue into the Hyland Group, although no significant silver mineralization has been discovered above the thrust. Mineralization within the system is primarily galena with manganiferous siderite gangue (AR 095930). Surface mineralization is hosted by manganese and iron oxides breccias (AR 097230).
The main Haldane zone consists of a 20 m by 5.8 m outcrop of strongly oxidized phyllitic quartzite breccia. The breccia consists of manganese oxides and goethite with weakly silicified and sericitized quartzite and diorite breccia clasts. No visible sulphide was noted.
Surface sampling on the Haldane zone in 1964 returned low values, the best being 288 g/t Ag, 0.73% Pb and 1.48% Zn over a width of 8.5 m. The 1978-1979 exploration was mainly directed toward tin and tungsten.
A chip sample taken from the main Haldane zone in 2011 returned 223 g/t Ag, 1.17% Zn, 0.62% Pb and 0.12 g/t Au over 3.6 m. A grab sample taken the same year returned 623 g/t Ag, 1.535% Zn, 0.513% Pb, and 0.029 g/t Au (AR 095930).
Diamond drilling in 2013 intersected 4.78 m of 83.8 g/t Ag, 1.09% Zn, 0.14% Pb, and 0.122 g/t Au, including 217 g/t Ag, 1.51% Zn, 0.06% Pb and 0.197 g/t Au in highly oxidized faults in hole HLD13-12.
