Cu, W, Bi, Pb, Zn, Mo
Across its 51 square-kilometer area, the Deer Horn Property hosts a number of other mineralized targets and zones containing copper, tungsten, bismuth, lead, zinc and molybdenum. Besides the gold, silver and tellurium identified in the PEA, the most abundant metals identified to date are tungsten and copper.
Copper and Copper Porphyry
Prospecting at Deer Horn in 2012 identified new showings indicative of a buried copper porphyry system. Samples collected from this zone produced results as high as 4240 ppm Cu and 6.6 g/t Ag. This new copper porphyry potential adds further exploration value to the property. You can read more about the copper porphyry indicators here, from our May 2018 PEA: Deer-Horn-PEA-Copper-Porphyry.pdf
Copper porphyries are in great demand worldwide due to their size and economics. Here's an overview of porphyry deposits.
Tungsten & Molybdenum Porphyry
The Deer Horn Property’s main tungsten showing is separate, lying 800 to 1,000 feet west of the main Te-Ag-Au vein system. The tungsten zone was noted in the PEA as follows:
“Prospecting, trenching and limited diamond drilling also confirmed the presence of important concentrations of scheelite (tungsten) mineralization on the property. The elevated levels of tungsten occur in the vicinity of the historic Harrison Scheelite mineral occurrence and locally in drill core over an east-west distance of at least 550m. The
mineralization appears to be particularly concentrated in altered sedimentary rocks in the footwall of the regional thrust (and Contact Zone)."
The PEA also notes: "A tungsten occurrence consisting of narrow, scheelite-bearing quartz veins hosted in quartz diorite and thermally altered volcanic and sedimentary rocks (Harrison Scheelite, Minfile 093E 020); and an area of anomalous molybdenum comprised of molybdenite-bearing quartz veins cutting andesitic volcanic rocks near the margin of an Eocene granodiorite intrusion (Cob, Minfile 093E 045). The latter two occurrences may be regarded as a porphyry tungsten system (Sinclair, 1995a) and a porphyry molybdenum (Low F-Type) system (Sinclair, 1995b), respectively. Additional exploration of the tungsten is recommended.”
Bismuth, Lead, Zinc and Molybdenum
Past exploration at Deer Horn has encountered significant amounts of bismuth, lead, zinc and molybdenum, associated with other mineralized zones or in separate areas of the property. These occurrences warrant further exploration.
