Bulk chemical analyses of 48 samples hydrothermal precipitates from seven polymstallic sulfide deposits at sea-floor spreading centers in the eastern Pacific reveal distinct patterns gold enrichment. High contents are found two deposits: Axial Seamount (45057 ' N, 130002 W), and southern Explorer Ridge (49045.6 130016.2 W). A large, 160-kg sample composed silica, barite, sphalerite top deposit gives up to 6,700 ppb Au, averaging 4,900 Au. Similar material 1,500 660 Detailed mineralogical...
Short-wave infrared (SWIR) field and laboratory spectra were used to identify characterize hydrothermal alteration mineral chemical variability in host rocks proximal the Izok Lake Zn-Cu-Pb-Ag volcanogenic massive sulfide (VMS) deposit Nunavut, Canada. The is hosted within a sequence of predominantly felsic pyroclastic Archean age that are regionally metamorphosed amphibolite facies. These characterized by muscovite-biotite-sillimanite chlorite-biotite-cordierite suite. Proximal deposit,...

The Howard's Pass district of sedimentary exhalative (SEDEX) Zn-Pb deposits is located in Yukon Territory and comprises 14 that contain an estimated 400.7 Mt sulfide mineralization grading 4.5 % Zn 1.5 Pb. Mineralization hosted carbonaceous calcareous and, to a lesser extent, siliceous mudstones. Pyrite minor but ubiquitous mineral the host rocks stratigraphically above, within, below mineralization. Petrographic analyses reveal pyrite has complex protracted growth history, preserving...
Demand for critical raw materials is expected to accelerate over the next few decades due continued population growth and shifting consumption patterns of global economy. Sedimentary basins are important sources new discoveries sediment–hosted Mississippi Valley–type (MVT) and/or clastic–dominated (CD) Zn–Pb deposits likely required mitigate future supply chain disruptions Zn, Pb, Ag, Cd, Ga, Ge, Sb, In. Herein we integrate public geoscience datasets using a discrete grid system model...
Three significant base metal deposits were recently discovered in the Finlayson Lake district, Yukon Territory, Canada; however, widely varying selenium contents (e.g., 1,100 ppm avg Se at Wolverine, 200 Kudz Ze Kayah, and 7 GP4F) have hindered their rapid exploitation. Observations data from district show a strong positive correlation between high-temperature (>300°C), copper-rich sulfide assemblages of volcanic-hosted massive (VHMS) content all minerals. Thermodynamic calculations for...
The Howard's Pass district (HPD) comprises 14 Zn-Pb sedimentary exhalative (SEDEX) deposits and is located within the Selwyn basin, Yukon, Canada. Although HPD renowned for its large accumulation of base-metal sulfides, in places Late Ordovician to Early Silurian host rocks also contain abundant carbonate-bearing fluorapatite (CBFA). This mineral present stratigraphically below, within, above SEDEX occurs as fine-grained layers that are interbedded with cherty carbonaceous mudstone. Electron...
Porphyritic rhyolite sills form an important component of the footwall Wolverine volcanogenic massive sulfide (VMS) deposit, Yukon, Canada, and occur proximal to mineralization in immediate deposit area (Wolverine/Lynx zone) at similar stratigraphic levels along strike (Fisher, Puck, Sable zones). rhyolites are two types: older quartz-feldspar porphyritic (QFP) suite; a younger feldspar (FP) suite. Both QFP FP suites intrusions semiconcordant, suggesting silllike morphology, altered crosscut...
We have investigated the application of ground, laboratory, and airborne optical remote sensing methods for detection hydrothermal alteration zones associated with Izok Lake volcanogenic massive sulfide (VMS) deposit in Nunavut, Canada. This bimodal-felsic Zn-Cu-Pb-Ag is located above tree line a subarctic environment where lichens are dominant cryptogamic species coating rocks. The immediate host rhyolitic rocks been hydrothermally altered contain biotite, chlorite, white micas as minerals....

Middle Devonian Ni-Mo-Zn-Pt-Pd-Au-Re hyper-enriched black shales (HEBS) from Peel River in north Yukon have high abundances of platinum group elements (PGE; ca. 500 ppb), Au (40–130 ppb) and Re (8–55 ppm). Mineralization occurs up to three thin (0.5–10 cm thick) layers that include the regionally extensive HEBS at Road Group-Canol Formation stratigraphic contact (e.g., correlative with Nick Ni-Mo-Zn-PGE-Au-Re prospect, northwestern Yukon); two other previously undocumented underlie upper...
