Multiple New Mineralised VMS Targets at Red Mountain Alaska
Geological reconnaissance follow-up of multiple stream sediment anomalies north of the company's large Last Chance IRGS-style gold anomaly between the known historic VMS prospects at Sheep Creek (Gossan Peak), Peaches and Keavy Peak (Grapple), discovered multiple exposures of massive sulphide mineralisation (Figure 1*) within a broad package of phyllites with discontinuous lenses of meta- rhyolite and carbonaceous black phyllite.
The main productive VMS stratigraphic package between Gossan Peak and Peaches trends east-west over a strike length in excess of 13km with a thickness of 500 to 750 metres. VMS mineralisation occurs as discontinuous stacked lenses or pods parallel to the east-west regional foliation, proximal to second order northwest and northeast trending faults.
White Rock's Technical Advisor Dr Quinton Hennigh commented:-
"White Rock's strategic district-scale tenement package, covering approximately 798km2, is the focus of two different but equally exciting large metal systems, one gold and one silver-zinc polymetallic (with lead, gold and copper). The Company's large Last Chance gold project, which has yielded a multitude of highly prospective stream sediment gold anomalies and early promising drill results, sits right next door to the Company's Red Mountain project which hosts a maiden VMS JORC Resource of 9Mt at 157g/t silver, 5.8% zinc and 0.9g/t gold, for a 13.2% Zinc equivalent (or 609g/t (19 ozs/t) Silver Equivalent) grade. As part of last summer's field campaign, follow up prospecting of stream sediment samples has led to the discovery of multiple new high priority VMS targets. Given these new discoveries, the Company's robust cash balance and recent market appreciation of silver and base metals, White Rock is seriously contemplating a parallel exploration program in Alaska in 2021 to focus on both the Last Chance gold and the silver-zinc VMS targets at Red Mountain. 2021 should be a very exciting time for the company."
Exposed massive sulphide mineralisation is limited to isolated outcrops on steep talus-dominated slopes. VMS lenses are coincident with podiform magnetic features identified by the airborne magnetics survey flown in 2020. Magnetic response, interpreted to be related to the presence of pyrrhotite (a magnetic iron sulphide), will allow a more accurate interpretation of the extent of the potential VMS lenses beneath the talus cover. A number of the magnetic features coincident with VMS lenses can be interpreted over strike lengths of 1.0 to 1.5km, similar to the VMS deposit dimensions that make up the Project's VMS JORC-compliant Resource further east at Dry Creek and WTF. More detailed ground magnetics, mapping and systematic surface geochemical sampling is being planned for early during the 2021 field season with drill testing potentially to follow.
