Whiskey Flat Project

High Grade Gold and Copper in Humboldt County, Nevada

Project Highlights

  • Main mineralization located on patented mineral claims
  • Accessible underground workings
  • Assays of 9.86 g/t Au, 92.9 g/t Ag, 1.63% Cu and 5.69% Zn over 11.9m underground, including 245.55 g/t Ag, 7.70% Cu and 11.08% Zn over 3.7m
  • Recent surface sampling with assays up to 635.0 g/t Ag, 11.05% Cu and 3.62% Zn
  • Surface samples yield significant cobalt mineralization assaying up to 0.15% Co

In February 2018, the Company entered into an Option Agreement, with an arms-length third party, to earn a 50% interest in the Whiskey Flat Project through cash payments, the issuance of common shares and certain work commitments over a 2-year period.

The property, with year-round access, is located 26 km southeast of Hawthorne, Nevada in the Excelsior Mountains.  Situated on 12 patented lode claims, owned or leased by the Optionor, and 47 unpatented lode claims under the jurisdiction of the Bureau of Land Management (“BLM”), the project area covers approximately 1,200 acres.

The main area of mineralization is located on the patented mining claims.  The property hosts numerous adits, pits, trenches and shafts from activity dating back to 1882, with subsequent activity from 1907 to 1914, and more recent underground mining activity from 1975 to 1977.  The most recent underground activity was carried out at the Quailey Mine which consisted of rehabilitating at least 400 metres of drifting with rail, air and water and completing 180 metres of new drifting and raising.

The project area is underlain by Triassic-age intermediate to felsic volcanics with limestone present locally.  These rock units have been intruded by Jurassic to Cretaceous granitic rocks which have generated hornfelsic rocks, skarns and related mineralization.

A number of types of mineralization have been documented on the property:

  • sphalerite (zinc) and chalcopyrite (copper) replacing limestone.
  • oxidized quartz veins with iron and copper oxides, copper carbonates with remnant sulphides and associated gold, silver, lead, and zinc.  This was the original target mineralization at the mine.
  • scheelite (tungsten) and powellite (molybdenum) in a garnet skarn.  Skarn-type mineralization is reported over a 1,200 metre strike-length.
  • magnetite bodies with 30% to 50% iron over 3-10 metre widths.
  • Silver-copper oxide mineralization along the contact zone with the granitic intrusion on 2 of the patented lode claims.

The Quailey mine is the largest of the historic mining operations on the property. The main focus of the mining was an oxidized quartz vein called the Shaft Quartz Vein, but drifting, cross-cutting and raising also intersected the other types of mineralization described below.

The Shaft Quartz Vein

This vein, which also outcrops on surface, composed of white to glassy quartz is highly oxidized with widths up to 4.5 metres encountered underground.  Historic assays from underground sampling have been reported as follows:

Sample Type Location Width m Au g/t Ag g/t Cu % WO3 %
Muck Cars 370 E&W Drift over 45.7m   4.6 0.5 94.9 0.72 -
Muck Cars 1040 SW XC 1.8 1.0 402.7 1.23  
Muck Cars 1240 S XC 1.8 0.4 19.5 0.54 0.17

Copper-Zinc Zone

This mineralization is the most interesting on the property and will be the main focus of ongoing exploration.  The zone is not strongly represented on surface, but it was intersected underground by the 330 NW crosscut exhibiting strong sphalerite/chalcopyrite mineralization over a width of 11.9 metres.  Historic assays (1975) from the crosscut intersection are:

Sample Type Location Width m Au g/t Ag g/t Cu % Pb % Zn %
Muck cars 330 NW XC 16.5m to 28.4m   11.9 9.86 92.80 1.63 0.27 5.69

Scheelite Mineralization

Scheelite, along with sparse powellite, is found throughout much of the Quailey Mine associated with the garnet skarn. Three raises were driven on scheelite mineralization with mixed results. The tungsten values were spotty with the highest being 1.34% WO3 over a width of 1.0 metres.

Magnetite Mineralization

Magnetite mineralization in small bodies occurs on surface and underground with related copper oxides. Historical assays from samples taken from a surface showing above the upper mine workings assayed 1.10% Cu over a 6.4 metre width.

Recent Exploration Work

2007
A small prospecting/sampling program was carried out over the property in August 2007. For the first time on the property cobalt was assayed and samples taken from the copper-zinc-type mineralization show significant cobalt values. Selected results are listed below:

Sample Type Au g/t Ag g/t Co % Cu % Pb % Zn % W %

2010

In November 2010, a ground magnetic survey was completed over part of the project area and resulted in identifying highly magnetic areas likely associated with the magnetite mineralization that could be prospective for copper and silver.

2012

In April 2012, a ground Time Domain Electromagnetic (“TDEM”) survey was carried out over part of the project area. As a result, a significant anomaly was identified with a high probability of being a bedrock feature. The orientation of the anomaly is consistent with the orientation of the various mineralization types found in the Quailey Mine, and potential drill locations were selected based on the survey results.

Future exploration work will focus on the copper-zinc zone originally discovered underground in the Quailey Mine in the 330 NW crosscut.

2018

In fall 2018, an initial ground reconnaissance survey was carried out over the Whiskey Flat property with a focus on the Quailey Mine. Geologists were able to safely access the Main Drift underground and take samples. Assays are pending.

As part of the Option Agreement, the Company was also granted a second option on a 200 tpd mill and millsite (see Red Rock Mill).

Note: The historical assay results and estimates noted above should not be relied upon. These results are not National Instrument 43-101 compliant. While the company considers these historical assay results and estimates to be relevant to investors as they may indicate the presence of mineralization, a qualified person for the company has not done sufficient work to classify the historical assays and estimates as current mineral resources as defined by NI 43-101, and the company is not treating these historical assays and estimates as current mineral resources.

Red Rock Mill

As part of the Option to earn into the Whiskey Flat project, the Optionor has included a secondary option to also earn a 50% interest in the Red Rock Mill and millsite by bringing the custom mill to commercial production capability.  The mill was used to process ore mined at the Quailey Mine in the 1970s and is currently configured as a gravity-flotation circuit capable of processing 200 tons of ore per day.  Mill capacity can be increased, but the current setup is ideal for processing bulk samples from test mining at the Whiskey Flat project in advance of commercial production, as well as custom milling material from other projects under development in the area.

The mill is located approximately 75 km from the Quailey Mine by all-weather road, on 6 millsite claims, under the jurisdiction of the BLM, near the town of Mina, Nevada.
