Gold Standard Ventures Consolidates Southern Carlin Trend District

 | May 22, 2014 01:56AM ET

All serious gold investors know the Carlin Trend of Nevada is one of the most prolific gold producing regions of the world. Is it possible that there is an undiscovered district, not just a deposit, within that region that was missed by the majors? Jon Awde, CEO of Gold Standard Ventures, discusses how spectacular drill results have guided Gold Standard Ventures to focus on creating the southernmost mining district of the Carlin Trend—the Railroad/Pinion District. At more than 40 square miles, the district is large enough to potentially sustain a mid-sized producer. In this interview with The Gold Report, Awde describes the unique challenges of proving up a series of deposits that are in the shadow of the majors and for the first time all combined under one company in a single mining district.

The Gold Report: The event that launched Gold Standard Ventures Corp. (AMEX:GSV):NYSE) into the limelight was the spectacular drill results of the high-grade and long interval at the Railroad project in Nevada. That was about two years ago. Since then, what have you learned about the deposit and how has the company evolved to take advantage of the situation?

Jon Awde: The intercepts that you are referring to were quite spectacular. In 2012, we had four wide and high-grade holes. At that time it was called the Railroad project. It's recently been renamed the Railroad/Pinion project. Two of the better holes had 164 meters (164m) of 3.38 grams per ton (3.38 g/t) and 124m of 4.05 g/t. One of those holes included a high-grade intercept of 42.7m of 9.4 g/t. That was a blind discovery and opened up this target. Since then, we have drilled at least 30 more holes into that target.

What have we learned? The deposit has complex geology. The deposit is open-ended. Both of those attributes describe a typical Carlin system, and they apply to the Railroad/ Pinion project. Late last year we discovered a new lower breccia zone that appears to be the flat lying collapse breccias that occur in an idealized North Carlin system. These are all characteristics that historically have represented a very large, robust Carlin system.

TGR: What was the depth from surface to the high-grade intervals? One of the many attractions of Carlin-style mines is that many are near surface.

JA: The depth of those specific holes was about 160 meters. We have found shallower portions of the deposit to the southwest, where we see mineralization starting at about 90 to 100 meters. If you look at other operating mines in the Carlin Trend, there are many that operate with similar depths to ore from surface.

TGR: Haven't the majors locked up all the Carlin Trend? Is there any room left for new big discoveries?

JA: Yes, absolutely, sometimes districts can remain underexplored because of complex land ownership issues or stacked royalties–both were the case at Railroad-Pinion. The Carlin Trend is the most prolific gold belt in the Western Hemisphere. The majority of the current production from the Carlin comes from the northern end of the trend. Gold Standard Ventures Railroad/Pinion District is in the southern portion of the Carlin Trend, immediately south of Newmont Mining Corp.'s (NYSE:NEM) Rain District.

Our chief geologist, Dave Mathewson, when he worked for Newmont, tried to get a toehold in the Railroad/Pinion District for years. Ultimately, his efforts were not successful. The land package was owned by various interests that could not work out a deal to advance exploration in the district. In the meantime, the majors developed several operating mines on the northern portions of the Carlin Trend and let this area sit under or unexplored.

Times change and we were highly opportunistic and diligent in working out terms with new owners in the area to move forward with exploration. In fact, the Railroad/Pinion District wasn't really explored with modern exploration techniques until we got to it. Gold Standard Ventures was the first company to do controlled source audio-frequency magneto tellurics (CSAMT) and gravity surveys at the district level. We were also the first to do soil sampling and geologic mapping across the entire Railroad/Pinion District.

TGR: What are some of the things you have found that indicate that Railroad/Pinion is the southernmost district in the Carlin?

JA: One distinctive feature of Carlin-style deposits is the presence of collapse breccias along major west-northwest trending fault zones. We discovered two such features at our North Bullion deposit. That is just the beginning, as we are getting a better handle on the structural controls to the geology. It's wide open and complex geology. Just when you think you have these Carlin systems figured out, they throw you a curve ball. Our team of exploration geologists, including Dave Mathewson, Mac Jackson and Steve Koehler, has been phenomenally successful in Nevada with several discoveries to their credit. The team has the expertise to model and interpret the new data that we have been able to obtain by consolidating these projects into one district. Such a districtwide view simply hasn't been possible in the past; while we are prioritizing three targets this year, the district remains target rich and highly prospective.

TGR: Who are the significant players in the Carlin Trend?

JA: Most of the Carlin Trend is controlled and operated by Barrick Gold Corp. (NYSE:ABX) and Newmont. In the northern part of the Carlin Trend is the Richmond Dome, which has the Goldstrike, Leeville and Meikle mines. Moving farther south down the trend is the Maggie Creek Dome, which is controlled and owned by Newmont. That's the massive Gold Quarry deposit. Next is the Mike deposit. Further south is the Rain District, which is primarily owned by Newmont, although the majority of the Saddle deposit is owned by Premier Gold Mines Ltd. (TO:PG). Then within the Rain District is the Emigrant mine that Newmont put into production a couple of years ago. That is a near surface, run-of-mine heap-leach operation that is generating good cash flow for Newmont. A good portion of the Emigrant deposit was discovered by Dave Mathewson of Gold Standard Ventures.

The most southerly district of the Carlin Trend is the Railroad/Pinion District. With the recently closed Pinion acquisition, Gold Standard Ventures now controls almost 40 square miles of wholly owned ground in the district. Each of the main districts in the Carlin Trend are all centered on a large dome or intrusive pluton. Gold Standard Ventures now controls the entire "fourth window," which represents the area where one of these large domes come close to surface and is most available for exploration and mining (see illustration below).
