[{"type":"text","content":"VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb. 2, 2017) - Gray Rock Resources Ltd. (TSX VENTURE:GRK) \"Gray Rock\" or the \"Company\") is pleased to announce the release of petrological and geochemical studies by the British Columbia Geological Survey (BCGS) from the July, 2016 discovery of coarse visible gold mineralization in bedrock along Otter Creek at the Godkin (Otter Creek) pit on the Company's Surprise Lake Project (BCGS Paper 2017-1, p.179-193). The road accessible Surprise Lake Project, 18 kilometers east of the town of Atlin in northwestern British Columbia, is owned by DeCoors Mining Corp. which has signed a binding letter of intent to transfer ownership of 33 mineral titles to Gray Rock Resources Ltd. (September 30, 2016 news release). The paper describes a different geological model to explain the coarse gold in bedrock along Otter Creek, different host rock, and the source of the nuggets found in the Atlin placers. This new approach significantly expands the target area for lode gold exploration in the Atlin mining camp. The following is a summary of the BCGS paper. Primary exploration targets for lode gold near Atlin, northwestern British Columbia, have historically been listwanite altered ultramafic and mafic bedrock (considered to be the source of the nearby placer deposits) and locally do contain fine visible gold. The discovery of coarse lode gold (>5 mm) in bedrock at the Otter Creek pit in 2016 on the Surprise Lake Project initiated the BCGS study. The study concluded that the coarse gold in bedrock, and probable associated placers, may be related to Jurassic age deformation and batholith development. The native gold in bedrock is intergrown with quartz-albite veins, and occurs as open space fillings and within both the quartz vein stockwork and encasing, commonly graphitic, sedimentary phyllite (see photos on following page or refer to page 185 of the paper). The study does not imply that an economic lode gold deposit has or will be found on the Company's Surprise Lake Project. However, this new conceptual model will serve to guide future exploration toward that end. Exploration on the Surprise Lake Project in 2016 returned significant results from the coarse visible gold discovery area along Otter Creek including three one meter samples of 42.1, 6.89 and 3.05 g/t Au, with grab samples of 20.8 and 4.1...
