Sanatana Resources Inc. (TSX-V:STA) has reported results from rock grab samples from the newly discovered Tarn Zone at its Oweegee Copper-Gold project in British Columbia's Golden Triangle.
The Vancouver-based mineral exploration company said the Tarn zone was discovered at the end of the 2021 Oweegee field program and is located over 8 kilometers (km) north of the known copper-gold showings at the Delta Zone. The Tarn Zone consists of a strong magnetic anomaly and anomalous copper-gold (Cu-Au) silt geochemistry and forms the eastern portion of the broader Skowill Prospect area of the 310 square km Oweegee property.
According to the company, significant grab samples returned 0.438%, 0.40% and 0.335% Cu. The highest-grade sample 420268 also reported 5.72% zinc (Zn). These are the best of the 13 samples collected from the magnetic anomaly, said the company.

Rock samples included chlorite, carbonate, magnetite altered volcanic rocks with quartz-magnetite-specular hematite-chalcopyrite veining within a 500 meter (m) wide magnetic high anomaly with coincident Cu-Au soil anomalies and visible gossans, said the company.
Sanatana said the results are “highly encouraging” for the initial sampling and confirm the Oweegee project hosts multiple mineralizing systems each of which requires follow-up study.
The magnetic anomaly was initially identified from historic airborne survey data which was truncated by the northern edge of the survey area. An additional 588-line km of airborne magnetic and radiometric surveys were completed in September 2021 which extended the coverage area and revealed additional magnetic anomalies which are scheduled for follow-up groundwork in 2022, said the company.
It added that the results of the new airborne survey show the Tarn prospect sits at the head of “a tadpole-like shaped magnetic high about 1.5km long with the gossanous ridge forming the tail.” Prospecting crews will be sent to this area during the 2022 field season to further develop this interesting and emerging prospect, noted the company.
The magnetic survey also revealed several other magnetic centers that could be a response caused by magnetite associated with potassic centers of other porphyry systems or skarns. These targets will also be highlighted for field investigation in the 2022 season, said the company.
The radiometrics, although somewhat influenced by vegetation cover, has proven to be a good proxy for a geological map. To the north of Skowill creek the data is dominated by a rock type with high potassium, probably an acid volcanic unit of the Jurassic Hazelton group. Elsewhere, contrasts between the various radiometric channels highlight areas of intrusives, sediments and previously unrecognized alteration zones.
Sanatana said these areas of interest will help guide the 2022 prospecting crews and emphasize the underexplored status of large portions of the Oweegee Property.
