Crystal Lake drills eight m of 15.11 g/t Au at Newmont

2019-09-18 08:28 ET - News Release

Mr. Richard Savage reports


Crystal Lake Mining Corp. has intersected shallow high-grade gold mineralization at its Newmont Lake gold corridor. The new results are crucial as they provide evidence of a thick unit of unusually high-grade gold mineralization within a broad envelop of continuous low-grade gold mineralization. This discovery is important as it demonstrates that the mineral zone actually increases in both width and in grade in areas where previous models indicate a narrowing of the mineral zone. Additionally, a second deeper horizon has been intersected in an area without gold mineralization in previous models adding to the exploration potential of the Newmont Lake gold corridor along the western flank of the Eskay Rift in northwestern British Columbia.

The first diamond drill core assay results from continuing drilling at the NW zone underscore the potential for higher grades and increased continuity of grade which can result in significant expansion of the historic mineralization while brand new high-grade domains are targeted elsewhere along the gold-bearing McLymont fault and numerous associated splay faults.


  • The second of three drill holes, building on the northern extension of the Northwest zone, intersected 15.1 grams per tonne Au over 8.03 metres (106.32 metres to 114.35 metres), including 76 g/t Au over one metre, in addition to an even shallower high-grade intercept of 7.6 g/t Au, 23.1 g/t Ag and 1.03 per cent Cu over 5.30 metres starting just 82 metres downhole (including 26.1 g/t Au over 1.3 metres).
  • These two shallow high-grade gold zones form a thick continuous intercept of 44 metres (82 metres to 126.13 metres, approximate true width) grading 4.03 g/t Au, 4.06 g/t silver and 0.29 per cent copper, in addition to a deeper wide interval of disseminated gold mineralization (77 metres at 0.29 g/t Au) starting 157 metres downhole which points to the potential for new discoveries including more high-grade mineralization at depth.
  • Continuing drilling of this significantly upgraded portion of the NW zone historic resource* has encountered visually similar mineralization in the third hole completed along section with an estimated down-dip stepout of approximately 22 to 30 metres. Assays are pending.
  • The fourth hole on section in the Newmont Lake Gold corridor is continuing.

Dr. Peter Lightfoot, technical adviser to Crystal Lake, commented: "The western flank of the Eskay Rift is endowed with significant high-grade mineralization styles that fit with a wide range of deposit models, and require very efficient pathways for fluids and magma to migrate from depth to the surface and form ore deposits. The gold mineralization developed along the western flank of the Newmont Lake graben is part of this wider mineral system, and Crystal Lake is aggressively developing an understanding of how the high-grade gold mineralization relates to the McLymont fault, its subsidiary faults and associated hydrothermal breccias."

This resource estimate was based solely on the drill hole data collected by Gulf Minerals in the late 1980s and early 1990s.

Quality assurance/quality control

Drill core samples from the Northwest gold zone were sent to MSALABS' preparation facility in Terrace, B.C., where samples were prepared using PRP-910 method. Core samples were dried, crushed to two millimetres, split 250 grams and pulverized to 85 per cent passing 75 microns. Prepped samples were sent to MSALABS' analytical facility in Langley, B.C., where 50-gram pulps were analyzed for gold using the FAS-211 method, fire assay AAS finish. Core samples were analyzed for 53 elements using the IMS-230 method, multielement ICP-MS 4-acid digestion, ultrafine trace level. Silver assay results greater than 100 g/t Ag and cobalt, copper, nickel, lead and zinc greater than 10,000 ppm were automatically analyzed by ore grade method ICF-6.

Crystal Lake Mining conducts its own QA/QC program where five standard reference material pulps, five blank reference material samples and two field duplicates are inserted for every 100 samples when analyzing core samples.
