Another Large Gold Anomaly Identified at Last Chance Alaska
White Rock's Technical Advisor Dr Quinton Hennigh commented:-
"White Rock's recently expanded land package continues to yield a multitude of highly prospective stream sediment gold anomalies. Collectively, there are approximately 30 sq km of drainages shedding anomalous gold across the Last Chance property indicating excellent potential for discovery. Geologically, these anomalies appear to be related to a series of Cretaceous age intrusive bodies generally following the same trend, a sign we are dealing with a Tintina type gold system. We are very eager to get back in the field to follow up on these new anomalies and define new drill targets to add to our already robust plans for drilling the main target area in 2021."
The new geochemical survey identified another strong gold anomaly located immediately west of Last Chance where 8 samples define a catchment area >5km2 with anomalous gold up to 124ppb, comparable to some of the peak results at the Last Chance gold anomaly. This new gold anomaly is located proximal to mapped felsic dykes and high level porphyritic intrusive rock that are elongate east-west adjacent to Last Chance (coded "Tvif", Figure 1*). These linear, late, high-level intrusive rocks were likely emplaced along prominent long-lived regional structures that were also active during the earlier Cretaceous intrusive and accompanying orogenic mineralisation events.
A further 6 gold anomalies are clustered to the south around the Last Chance gold target, where the associated Cretaceous age granites (coded "Kg") are interpreted to trend beneath the surface at relatively shallow depths. The spatial clustering of gold anomalism, together with shallow structural controls in the form of hydrothermal silica breccias that host gold mineralisation identified at Last Chance, suggests this region of gold anomalism could represent an area where structures tap a strong, long lived, fertile gold-rich intrusive system at depth, with the potential for an array of trap sites that could yield significant mineralisation close to the surface.
White Rock is currently undertaking a detailed magnetics interpretation including advanced 3D inversion modelling to define the shape of the source intrusion at depth, and the upper structural architecture that provide fluid migration pathways for mineralisation sourced from the granites. Integration of the new areas of gold anomalism with the structural interpretation is expected to yield numerous targets for aggressive focused surface prospecting and drilling during the 2021 season.
