The > 20M oz Donlin Creek gold deposit is similar to Brewery Creek in structural setting, geochemical signature and mineral paragenesis and there is the potential for a comparable Au resource at Brewery Creek.”



New Trends Being Discovered?



In this thesis paper, the author suggests parallel systems may be prospective for gold, similar to the Reserve Trend.  We have tested North Slope and Moosehead to confirm this… so far so good. 



Here we see a geochem map in which I’ve outlined mineralized trends observed at Brewery Creek:

Bulk Tonnage Potential at Classic/Lone Star Discoveries?



From a GPD News Release dated October 11, 2012:



Lone Star Zone



The Lone Star Zone lies approximately five km south of the main Reserve Trend, and confirms the potential to open the entire southern portion of the large Brewery Creek Project to further exploration and discovery. Based on the encouraging results at Lone Star, the Company has recently added a second diamond drill to the Project and is currently working on defining the Lone Star Zone and expanding the Classic resource.



Mineralization occurs in Monzonite Sills (Pink Areas) and now known to occur in the Syenite Plutons (Red Areas).  Most juniors in the Tombstone Plutonic Suite focus their exploration on the pluton and their aureoles e.g. Victoria Gold at Eagle Zone.  These intrusions often host significant concentrations of gold in a series of sheeted veins, leaving significant potential for bulk tonnage resource expansion at Classic, Lone Star and Lead Dog.  Eagle Zone contains close to 10m oz while Donlin Creek has over 20m oz. 



Here we see a map of the different rock units.  We’ve been finding gold throughout the Monzonite Sill (Pink Areas) formations and we’re about to drill out the Syenite Intrusions (Red Areas):





From a Northern Miner article dated November 12, 2012:



“We have some exploration targets with the Classic and South Classic [Lone Star] zones, and feel that particular intrusion could be the source of the gold-bearing fluids in the whole campSo we’re obviously excited about the size potential there,” Burke says. The company is mapping the area in a bid to cut higher gold grades in future drill campaigns, and Burke notes that the area “responds really well to heap leaching. It’s just a mineralized intrusive body, within that there seems to be the structural zones where the gold-bearing fluids have migrated through. That’s what we’ll be trying to key in on for potentially higher grades.”



Below you’ll find a visual representation of our existing gold resource (in yellow and red).   Bill Sheriff, CEO, has estimated 3-5Moz gold at Brewery Creek based on just the known targets.  Look at the geochem and rock unit maps again and you can clearly see the resource potential.
