Thorn Project: A District Scale Cu-Au Porphyry System
Sorin Posescu, Vice President Exploration
The 997 square-kilometre wholly owned Thorn Project is located in northwestern British Columbia, Canada, at the northern end of the Golden Triangle approximately 90 km ENE from Juneau, Alaska and 65km from tide water.
The Thorn Project is at the exploration-stage hosting several styles of mineralization related to epithermal and porphyry environments.
The Thorn Project is located in a district scale Triassic to Eocene volcanoplutonic complex. Triassic Stuhini Group rocks have been intruded and overlain by Jurassic, Late Cretaceous to Eocene bimodal volcanoplutonic complexes. The Thorn Project is hosted in similar geology to deposits including KSM, Brucejack, Red Chris, Galore Creek and other major deposits within the Golden Triangle.
Numerous showings and mineralization types occur on the property: Oban Diatreme Breccia (Ag-Au-Cu-Pb-Zn) which returned 95m of 900 g/t AgEq, Glenfiddich and Talisker Zone HS Breccia-Veins (Au-Ag-Cu), Outlaw Zone Sediment-Hosted Au-Ag and the Chivas Zone Au-Ag veins and Porphyry Cu. An inferred resource of 21.5Moz AgEq (7.4Mt at 89.75 AgEq) was established on the Oban, Talisker and Glenfiddich Zones combined in 2014 by SRK Consulting. All zones remain open for expansion. The scale and patterns of alteration and mineralization are similar to other large porphyry systems such as Bingham Canyon.
A total of 29,169 m of drilling within 170 diamond drill holes has been completed on the property.
There was no reported work at the Chivas Zone until 2014, when Brixton ran a single 700 m long soil line on a break in slope in the area. Most of the soil samples returned highly anomalous gold values with a high of 11.00 ppm Au, 12.70 ppm Ag and 11.4 ppm Te. Drilling of 10 core holes at the Chivas Zone in 2017 identified intermediate sulfidation polymetallic gold veins as well as copper mineralization near a large porphyry intrusive body (1700 m strike length). This represents a new discovery on the property, with high potential for a large-scale porphyry copper system at depth below the transitional porphyry copper environment mapped at surface and intersected in drilling. Several holes ended in increasing Cu (+/-Mo). Ongoing work at Chivas has identified the full spectrum of classic porphyry copper deposit vein types and has shown that potassic alteration is more extensive than previously recognized. Highlights of drilling in 2017 include:
* Hole 142 intersected 6.45m of 2.63 g/t Au, 45.15 g/t Ag, 0.18% Cu, 0.42% Pb, 1.50% Zn within 18m of 0.99g/t Au, 19.46 g/t Ag, 0.18%Pb, 0.66% Zn from 161m depth
* Hole 143 intersected 8m of 0.71 g/t Au, 202.49 g/t Ag, 0.34% Pb, 0.35% Zn within 11m of 0.54 g/t Au, 147.78 g/t Ag, 0.25% Pb, 0.27% Zn from 59m depth
* Hole 144 intersected 17.26m 0.61 g/t Au, 110.27 g/t Ag, 0.36% Pb, 0.36% Zn within 52 m of 0.31 g/t Au, 39.56 g/t Ag from 133.62m depth
Mr. Posescu is a professional geologist with more than 20 years of experience in natural resources exploration and development, including work on world class deposits as 40+M ounces gold Donlin Gold currently owned by Barrick and Novagold, and Galore Creek porphyry deposit, currently owned by Teck and Newmont.
Mr. Posescu has worked for major and junior resource companies throughout Europe, USA and Canada and has extensive experience in M&A and strong background in corporate and project valuation.
Mr. Posescu has held executive positions and served on the Board of Directors of several publicly listed and private companies and is a registered Professional Geologist with the Association of Professional Geoscientists of British Columbia, Alberta and Ontario.
