Heidi
Yukon Territory, Canada
Overview:
- intrusion-related gold system ("IRGS")
- situated within the Tombstone Gold Belt, in the Tintina Gold Province (TGP)
- coincident induced polarization (IP), magnetic, and gold-arsenic-antimony soil geochemical anomalies covering 1,000 m by 500 m area
- gold mineralization traced along surface for 2 km and chip samples from trenches returned values ranging from 1 to 7 g/t gold over 1 m widths with a maximum of 19.9 g/t gold from grab samples
- airborne magnetic survey indicates a large untested Tombstone-type intrusion (6 km diameter)
- gold mineralization intersected in 16 of 21 holes over a 1 km strike extent, in 2006 and 2007 diamond drill programs
- diamond drill results include 2.09 g/t Au and 9.5 g/t Ag over 4 m, including 4.04 g/t Au and 18 g/t Ag over 2 m with anomalous arsenic (As), antimony (Sb), and bismuth (Bi)
- recommended follow-up includes structural mapping followed by further drilling with deeper holes
Location & Ownership:
- 100%-owned (subject to 2% NSR)
- 95 km northeast of Dawson City, Yukon (30 km east of the Dempster Highway)
- 220 claims covering approx. 4,074 hectares (10,067 acres)
Exploration Target:
The target is an intrusion-related gold system (IRGS). The property lies within the highly prospective Tintina Gold Belt, which constitutes an arcuate belt of gold deposits that are directly associated with mid Cretaceous intrusions extending from Donlin Creek in Alaska, through the Fairbanks District (including Fort Knox; 169 Mt @ 0.93 g/t Au), Pogo and across the Yukon border where it incorporates the Tombstone Gold Belt; a 200 km long belt of gold deposits associated with the Tombstone plutonic suite, with examples including Dublin Gulch (66 Mt @ 0.92 g/t Au) and Brewery Creek (10 Mt @ 1.4 g/t Au).
Mineralization at Heidi has strong similarities to occurrences such as Mike Lake and Scheelite Dome (Yukon) where the gold mineralization occurs as vein and replacement bodies within the metasedimentary rocks outboard of Tombstone intrusions.
A new discovery was made at Mike Lake (15 km southwest of Heidi) in 2007 with 89.3m grading 0.61% copper, 1.38 g/t Au and 13.6 g/t Ag obtained from the only drill hole testing the zone. Results from Scheelite Dome include 2.21 g/t Au across 10.1m, 1.03 g/t over 20.3, 7.09 g/t Au across 6.4m, and 24.42 g/t Au over 1.7 m in drilling.
The buried intrusion at Heidi has potential to host Fort Knox/Dublin Gulch style intrusion hosted mineralization.
