White Rock's 2020 exploration at Red Mountain included a sampling program around the recently discovered Last Chance gold target at the western end of this large Alaska project.

White Rock Minerals Ltd. Dec. 21 announced that 2020 stream sediment sampling identified a large, robust gold anomaly west of the Last Chance gold target on the company's Red Mountain project in Alaska.

Best known for its zinc-rich volcanogenic massive sulfide (VMS) deposits and occurrences, the 308-square-mile (798 square kilometers) Red Mountain property lies within the Tintina Gold Belt, a particularly gold-rich province that sweeps across Canada's Yukon Territory and Alaska.

A detailed regional stream sediment program completed in 2019 led to the discovery of Last Chance, a large gold prospect at the west end of the district-scale Red Mountain property.

White Rock says that the 2020 sampling program has identified six additional stream sediment gold anomalies in the area surrounding Last Chance, all proximal to Cretaceous granites mapped throughout the southern portion of the company's district-scale land package.

"White Rock's recently expanded land package continues to yield a multitude of highly prospective stream sediment gold anomalies," said Quinton Hennigh, a technical advisor to White Rock Minerals. "Collectively, there are approximately 30 square kilometers (11.6 square miles) 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."

White Rock carried out an eight-hole drill program during the 2020 season that tested four targets on the originally identified Last Chance anomaly – Pickle, Sidewinder West, Sidewinder Blowout, and Double Down.

The highest grade intercept from the drilling was 1.2 meters averaging 24.8 grams per metric ton gold in hole LC20-07 drilled at Sidewinder.

Overall, White Rock says the assay results from the 2020 Last Chance program show a large system of strongly anomalous arsenic and antimony consistent with what has been interpreted to be the upper brittle levels of a large orogenic or intrusion related gold system.

"Our first eight holes tested very shallow parts of the system and all encountered intervals of anomalous gold mineralization, a very positive outcome. Importantly, hole LC20-07 encountered 1.2 meters grading 24.8 g/t gold, a clear demonstration the hydrothermal system is capable of generating high gold grades. The structure that hosts this interval is likely tapping deeper parts of the system where we expect to encounter more such mineralization," said Hennigh. "Although we did not get to drill deeper holes this season, we now understand the structural framework of this very large gold system."

White Rock's 2020 sampling program identified six new stream sediment gold anomalies (green) around the original Last Chance stream sediment gold target (purple).

The six newly identified gold anomalies are clustered to the south of the original Last Chance gold target, where the associated Cretaceous age granites are interpreted to trend beneath the surface at relatively shallow depths. White Rock said the clustering of gold anomalism, together with shallow structural controls in the form of hydrothermal silica breccias that host gold mineralization at Last Chance, suggests the potential for an array of trap sites that could yield significant mineralization close to the surface.

White Rock is interpreting magnetic geophysical data to define the shape of the source intrusion at depth, and the upper structural architecture that provide fluid migration pathways for mineralization sourced from the granites. The company says integration of the new areas of gold anomalism with the structural interpretation is expected to yield numerous targets for surface prospecting and drilling during the 2021 season.

"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," said Hennigh.
