Mayo Lake Claims Groups, Yukon Territory

Mayo Lake Minerals - Yukon Properties

Mayo Lake Minerals Inc. (MLM) is a Yukon-focused exploration company that has taken advantage of data overlooked during the last Yukon staking rush to establish a highly prospective portfolio. The late Dr. Chris Gleeson supervised the collection of high-quality geochemical data in the vicinity of Mayo Lake in the 1960s during the Geological Survey of Canada’s Operation Keno, which was never digitized and has consequently been overlooked by explorationists. This data suggests that the placer gold in the Mayo placer district is locally sourced in the uplands surrounding the placer creeks. Utilizing the data from Operation Keno as a guide, MLM decided to acquire and explore numerous properties around Mayo Lake.

MLM believes that the Mayo placer district hosts the same potential as the White Gold district prior to 2009. Nearly every creek is a current or past producer of gold and very little geochemistry or geophysics has ever been completed to locate the source of gold. Recent action by major gold miners in the area including Barrick Gold’s strategic investment in Atac Resources (40 km northeast of MLM’s properties), Victoria Gold’s ongoing expansion and development of its Eagle Gold Project at Dublin Gulch (20 km north of MLM’s properties), and Newmount Mining Corporation’s joint venture on Goldstrike Resources Ltd’s Plateau property (40 km southeast of MLM’s properties) are testament to the potential for gold discovery of this historic placer district.

On MLM’s most advanced property, the Anderson-Davidson claim group, MLM has defined a 10-kilometre-long gold trend (Figure 1) three robust drill-ready gold targets within the trend, in spite of the fact that much of the property has not been screened by geochemical or geological surveys. Significant associated geochemical-geophysical anomalies have been located on all MLM’s other properties that need more work to refine drill targets.

The Anderson-Davidson claim group is the most advanced property in MLM’s portfolio with three drill ready targets within the greater than 10km long Anderson Gold Trend. Other positives for gold mineralization are two producing placer operations within the property boundaries, as well as numerous former placer producers. Test pits have yielded float assay up to 3.5g Au/t within a gold anomaly with values from 0.1 to 0.5g Au/t in the soil. Anderson-Davidson has a four-wheel-drive road that runs the length of the claim group.

The Trail-Minto claim group contains the Roaring Fork Stock, a member of the Tombstone Plutonic Suite with dimensions similar to the Dublin Gulch stock, which hosts Victoria Gold’s Eagle Gold deposit. Two past producing placer operations are present on creeks draining this property and numerous gold in soil anomalies suggest portions of the Roaring Fork Stock and adjacent country rock may be well mineralized. A series of parallel gold anomalies, 3,500 m in length, straddle the Roaring Fork Stock-/country rock contact. Trail-Minto is road accessible.

The Carlin-Roop claim group is located on the western margin of the Roop Lakes Stock, another member of the Tombstone Plutonic Suite. Despite very little work, this property has demonstrated significant potential for Keno Hill type high grade silver mineralization. The active placer operation on Granite Creek maintains a seasonal road onto the property.

The Edmonton claim group sits on the Robert Service Thrust between the eastern arms of Mayo Lake. It is bordered on one side by Edmonton Creek, a former placer gold producer. Numerous mafic stocks, structures, geophysics and geochemistry point toward gold mineralization. A gold in soil anomaly parallels one edge of probable alteration zone defined by geophysics.

The Cascade claim group is located on highlands between two former placer gold operations on Cascade and Nelson creeks. Reconnaissance soil sampling on Cascade yielded up to 2.25g Au/t in soil. This claim group is easily accessible from Mayo Lake.
