Rosy
(epithermal gold-silver)

RosyHighlights

  • Owned 100% by ATAC
  • Located 5 km southeast of the Red Mountain porphyry molybdenum development stage project owned by Tintina Metals
  • Accessible by all-weather road to Red Mountain, which crosses the Rosy property
  • At least 35 gold and silver bearing, low sulphidation epithermal veins occur on the property
  • A grab sample from the R2 vein returned 35.9 g/t gold
  • Strong gold-in-soil geochemical anomalies occur in parts of the property where limited prospecting has not yet located accompanying bedrock vein mineralization

Geology & Mineralization

Geology

The property is underlain by a foliated Jurassic granodiorite body that intrudes Paleozoic aged metamorphic rocks that are further intruded by Late Cretaceous quartz-feldspar porphyry dykes.

Mineralization

At least 35 quartz-carbonate veins have been discovered on the property. They occur within fault zones, alongside young quartz-porphyry dykes and in adjacent altered granodiorite. They are recessive and rarely seen in outcrop. Mineralization consists of pyrite and lesser arsenopyrite that comprise up to 10% of the vein material. Finely disseminated sulphides also occur in quartz veinlets that occur peripheral to the main veins. Prospecting grab samples assayed up to 35.9 g/t gold.

Three short diamond drill holes were completed on the property in 2010, with the best result being 2.29 g/t gold across an intersected vein width of 2.29 metres. Further prospecting and geophysical surveys were recommended in 2010 by the Company's consultant to develop bulk tonnage drill targets southeast of the drill holes, in a geochemically anomalous area of low topographic relief covered by glacial till and vegetation. This geochemical anomaly remains undrilled.
