Two main zones were identified on the Property, the Pelham Zone and West Contact Zone. Most of the drilling was done in a small part of the Pelham Zone. Initial resource estimate of 300,000 oz of gold (not NI43-101 complaint) was calculated from drilling in this Zone.
Trench samples collected from the West Contact Zone during the 2006/2007 exploration campaign returned between 1.0-9.8 g/t gold, including 8.02 g/t gold over 39.0 m and 89.4 g/t gold over 3.0 m. Little follow up work was done in this area which will be one of the main focuses of the Company's upcoming exploration program.
Highlights of drill results from historic work and the recent drilling by Teck (2007 and 2008) and Laurentian Goldfields (2011) include:
- 113.0 m @ 1.72 g/t Au (88-10)
- 60.30 m @ 1.46 g/t Au (88-05)
- 55.25 m @ 2.19 g/t Au (TC08-11), including 1 m @ 37.5 g/t Au, 9.34 m @ 7.91 g/t Au and 21.73 m @ 4.63 g/t Au
- 29.66 m @ 0.77 g/t Au including 9.04 m @ 2.20 g/t Au (TC08-09)
- 68.8 m @ 1.55 g/t Au (TC11-001)
- 81.0 m @ 1.31 g/t Au (TC11-006)
The highest grade from historical drilling returned up to 192.7 g/t gold over 0.55 meters.
Fladgate Exploration Consulting was contracted in 2011 to create a 3D resource model of the Thundercloud historical drill data, assuming a specific gravity of 2.7 for all rocks. The model for the Pelham Zone exploration target showed an estimated potential amount of contained gold of 300,000 ounces, at a head grade of 1.6 g/t Au, using a 0.5 g/t cut-off grade, in the different grade shells. This initial resource estimate was developed for targeting purposes, and it is not National Instrument 43-101 compliant.
The Company is currently reviewing and compiling past exploration data on Thundercloud to define targets to augment the current historical resource and to follow up on the past trenching results.
