Triumph Gold Corp. Sept. 12 reported that this year's deep drilling program has encountered the buried porphyry gold-copper mineralization being targeted at the first of three areas being tested on the company's Freegold Mountain Property in the Yukon Territory.
Over the years, Triumph has identified several near-surface, gold-copper targets and deposits over a six-kilometer (3.7 miles) stretch of Freegold Mountain. The two most advanced deposits along this trend are Nucleus and Revenue.
Nucleus hosts 74.74 million metric tons of indicated resource averaging 0.54 grams per metric ton (1.3 million ounces) gold and 0.06 percent (105.3 million pounds) copper; plus 63.79 million metric tons of inferred resource averaging 0.4 g/t (800,000 oz) gold and 0.05 percent (491,800 lb) copper.
Revenue, located about 3,000 meters east of Nucleus, hosts another 80.8 million metric tons of inferred resource averaging 0.39 g/t (1 million oz) gold and 0.14 percent (241.4 million lb) copper.
Triumph Gold geologists believe the 6,000-meter-long multi-element encompassing these zones and deposits is underlain by a large buried porphyry intrusion that has yet to be tested by drilling. This year's program targeted this buried porphyry potential with a drill rig capable of reaching depths up to 2,000 meters.
WAu Breccia, a copper-gold-silver-molybdenum-tungsten-bearing target immediately east of the Revenue deposit, was tested with two holes.
RVD19-02, the second WAu Breccia hole, cut 400.5 meters of epithermal style mineralization averaging 0.73 grams per metric ton gold, 6.9 g/t silver, 0.23 percent copper and 0.025 percent molybdenum starting a depth of 77.5 meters.
Starting at 560.5 meters, this same hole tapped 102.5 meters of gold-rich porphyry related mineralization averaging 0.73 g/t gold, 1.5 g/t silver, 0.18 percent copper and 0.055 percent molybdenum.
"At the WAu Breccia, the first of three areas being drill tested in 2019 for buried porphyry mineralization, we have discovered a porphyry copper-gold system, said Triumph Gold Vice President of Exploration Tony Barresi. "The discovery intersection is long, high-grade, gold-rich and closer to surface than we had expected. We also more than doubled the known depth of the near surface, gold-rich, epithermal style WAu Breccia."
Triumph originally planned to drill six deep holes this summer – two each at WAu Breccia, Big Red and Blue Sky.
Given the results from RVD19-02, the company has expanded the program to include a third hole at WAu Breccia.
"Now, with the addition of a seventh drill hole to the program, we'll be further delineating deep WAu this year," said Barresi.
