Bravada's Proof-of-concept Drilling Provides Vector to Feeder Zone at Wind Mountain Au-Ag Property, Nevada
Vancouver, British Columbia--(Newsfile Corp. - January 17, 2018) - Bravada Gold Corporation (TSXV: BVA) (OTCQB: BGAVF) (FSE: BRTN) (the "Company" or "Bravada") reports that two proof-of-concept holes were completed in December and early January at the Company's 100% owned low-sulfidation Wind Mountain project, a past-producing gold/silver property in northwestern Nevada. The reverse-circulation holes were drilled approximately 1,500m apart. Alteration and geochemistry indicate that the southerly hole intersected mineralization with characteristics of being up-dip from a feeder zone and the northerly hole intersected characteristics of being down-dip from a feeder zone, indicating the feeder lies between these holes (see figure below). Each hole intersected a low-angle fault that separates the Tertiary volcanic and sedimentary host rocks from Mesozoic metamorphosed basement rocks.

Hole WM17-097 (-75, 135 degrees, TD= 401m) was drilled close to the South End Inferred Resource and intersected strongly clay-altered sediments and tuffs within the lower Pyramid volcanic sequence. Anomalous gold (50-699ppb) and mercury (+1ppm) occur in this rock sequence before passing into unaltered Mesozoic basement rocks at 279m depth (see cross section below).

Hole WM17-098 (-75, 135 degrees, TD=634m) was drilled from the bottom of the Wind Mountain open pit and drilled through a portion of the previously defined resource, where assays in hole -098 returned 0-40m averaging 0.343g/t Au (0.510g/t Au-eq using a 70Ag:1Au ratio) as expected. Alteration, gold and pathfinder elements decreased to background levels and continued at these low levels down hole to 524m, below which assays are not expected until mid-February. Unaltered Mesozoic basement was intersected at 617m depth. Pyramid sediments are much less altered than similar sediments intersected in hole -097 (see cross section below, note change in scale from WM17-097 section).

President Joe Kizis commented, "The two proof-of-concept holes in combination with existing data provide us with clear vectors to the likely feeder zone, also called the upwelling zone in low-sulfidation gold deposits. Evidence is overwhelming for large-scale lateral movement of the gold-depositing fluids that formed the known gold/silver deposit, which makes zeroing in on the suspected high-grade feeder difficult. However, the difference in alteration is striking within similar volcanic-sediments above basement rocks; those in hole -098 appear to be essentially unaltered, even though they underlie the thickest portion of the shallow mineralization, whereas those volcanic-sediments in hole -097 have alteration and mineralization that is typical of being distal from an upwelling zone. The challenge now is to determine where the feeder zone(s) lies within this area of approximately 1km by 0.5km. IP or another geophysical technique should assist in refining drill targets to be drilled in the second quarter 2018, subject to rig availability."
About Wind Mountain
The Wind Mountain Property is in northwestern Nevada approximately 160km northeast of Reno in a sparsely populated region with excellent logistics, including county-maintained road access and a power line to the property. It is an historic past-producing, bulk-tonnage gold-silver mine. An independent resource estimate and Preliminary Economic Evaluation for Wind Mountain commissioned by Bravada in 2012 reported:
- 570,000 ounces of gold and 14.7 million ounces of silver in the Indicated category, and
- 354,000 ounces of gold and 10.1 million ounces of silver in the Inferred category.
See the table below and news release NR-06-12 dated April 11, 2012 for details of the resource update. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be classified as mineral reserves. There is no assurance that any part of the resources will ultimately be converted to mineral reserves.
Mine Development Associates compiled the Technical Report and PEA. Thomas Dyer, P.E. is a Senior Engineer for MDA and is responsible for sections of the Technical Report involving mine designs and the economic evaluation, and Steven Ristorcelli, C.P.G., is a Principal Geologist for MDA and is responsible for the sections involving the Mineral Resource estimate. These are the Qualified Persons of the technical report for the purpose of Canadian NI 43-101, Standards of Disclosure for Economic Analyses of Mineral Projects. Details of the PEA produced by Mine Development Associates (MDA) of Reno can be found on SEDAR, as previously reported (see NR-07-12 dated May 1, 2012). Note that although the PEA was encouraging, it is preliminary in nature, it includes Inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized.
