White Rock Minerals (ASX: WRM) has significantly expanded its district-scale tenement package, including the Last Chance gold target, at its 100% owned Red Mountain Project in Alaska.
The expanded tenement area now forms a strategic and contiguous block of mining claims that cover an extensive area prospective for IRGS mineralisation including the Last Chance gold target, as well as multiple VMS prospects including the high-grade zinc-rich deposits at Dry Creek and WTF with an Inferred Mineral Resource of 9.1 million tonnes @ 12.9% ZnEq, for 1.1 million tonnes of contained zinc equivalent.
During the 2019 field season, White Rock completed a detailed regional stream sediment programme that identified the Last Chance gold target. The expanded tenement package covers a larger anomalous geochemical signature typical of IRGS systems associated with Cretaceous granites in the Tintina Gold Province. World class gold deposits associated with Cretaceous granites in the Tintina Gold Province include Donlin Creek (45Moz gold) owned by NovaGold and Barrick, Fort Knox (13.5Moz gold) owned by Kinross and Pogo (10Moz gold) owned by Northern Star.
The Last Chance Gold Prospect is a large, 15 sq. km robust gold anomaly defined by 27 stream sediment sample points. The gold anomaly has a highly anomalous core >100ppb gold in first order stream catchments over 3.5km of strike east-west, and at >75ppb gold extends over 6km of strike.
The gold anomaly is located in the headwaters of Last Chance Creek. Downstream from this Prospect, significant placer workings commence 12km to the north and extend further north downstream through the foothills of the Alaska Range.
