- 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
The Rosy property comprises 353 contiguous mineral claims located on the Red Mountain access road, 77 km east-northeast of Whitehorse. The property hosts widespread gold-and-silver bearing veins that appear to be associated with Late Cretaceous intrusive activity. Mineralization on the Rosy property is indicative of the distal part of a large hydrothermal system, likely in a low-sulphidation epithermal setting.
The Rosy property hosts two main types of mineralization. The first occurs within quartz carbonate veins, while the second is found in altered intrusive rocks. Over 30 separate quartz-carbonate veins have been mapped on the property and occur with gouge zones, quartz-feldspar porphyry dykes and carbonate altered wall rocks. Historical mineral showings on the property include:
- a 15 m to 20 m wide area of rusty orange soil containing quartz-carbonate vein float and minor amounts of altered intrusive rock. Samples of vein material returned values ranging from 2.14 to 4.42 g/t gold
while samples of altered intrusive rock yielded 1.09 and 1.79 g/t gold.
- a 20 m wide area of orange-brown rusty soil containing scattered quartz-carbonate float, which has assayed up to 35.92 g/t gold
. In 2008, five rock samples from R2 returned between 2.41 and 5.84 g/t gold
- consisting of two samples taken approximately 200 m apart. The first sample was collected from a saddle on a ridge and yielded 1.45 g/t gold with 7.7 g/t silver. The other sample was found 200 m west of the ridge crest on a west facing talus slope and returned 0.536 g/t gold, 1.7 g/t silver.
In 2016, ATAC conducted a two day prospecting and soil sampling program, collecting 32 rock samples and 115 soil samples. Three of the vein samples collected 350 m north of the R3 vein zone returned 12.55, 6.52, and 5.20 g/t gold with 93.10, 13.85, and 11.05 g/t silver
, respectively. Two rock samples collected 295 m north of the R2 vein returned 5.86 and 2.57 g/t gold with 3.76 and 73.1 g/t silver, respectively.
In 2017, two rock samples of significance were collected from the property. The first sample was located northwest of R1 and returned 4.57 g/t gold and 83.9 g/t silver. The second rock sample was collected two kilometers northeast of the R1 vein and assayed 1.74 g/t gold and 30.0 g/t silver.
All occurrences and soil anomalies have seen limited exploration and require systematic follow-up work. The property hosts an extensive system of precious metal enriched veins and is expected to yield additional discoveries with thorough exploration.
