Western Exploration Intersects 74.22 Meters of 1.71 g/t Au and 40.40 Meters of 2.18 g/t Au From the Doby George Deposit at the Aura Project (Elko County, NV)






Western Exploration Inc. (TSX-V: WEX) (OTCQX: WEXPF) is pleased to provide additional assay results for three holes from the Phase 1 drill program at Doby George, one of three main mineral deposits located at the Company’s wholly-owned Aura project, located in Elko County, Nevada.



  • DGC791 intersected 74.22 meters of 1.71 g/t Au, including 30.78 meters of 2.48 g/t Au
  • DGC792 intersected 40.39 meters of 2.18 g/t AuFA
  • DGC793 intersected 26.98 meters of 2.12 g/t Au and 19.20 meters of 1.46 g/t Au


Darcy Marud, Chief Executive Officer and Director of Western Exploration, commented: “Holes DGC791 to DGC793, have all been completed in the West Ridge and Daylight areas at Doby George. We have now received assays results for five of the nine drill holes completed at Doby George and all of them demonstrate the remarkable continuity of high grade, near surface, oxide gold mineralization at Doby George.”


The complete results for holes DGC791, DGC792 and DGC793 are reported below in Table 1, along with assays reported on October 26. Assay results for the remaining four drill holes are pending.

(3) DGC791 AuCN/AuFA ratios ranged from 33 to 133%, based on 57 samples, with only 5 samples below 80%; DGC792 AuCN/AuFA ratios ranged from 21 to 98%, based on 26 samples, with 12 samples below 80%; DGC793 AuCN/AuFA ratios ranged from 15 to 98%, based on 27 samples, with 12 samples below 80%; all AuCN values were capped at 100% of the AuFA assays.


All sample intervals were assayed by both fire assay (AuFA) and cyanide soluble shake tests (AuCN) followed up by atomic absorption finish. The AuCN results are a measure of the solubility of Au in dilute CN solutions and the state of oxidation of the samples. An AuCN/AuFA ratio of greater than 80% generally indicates strong oxidation and good cyanide extraction potential.




The Phase 1 drill program was comprised of nine large diameter (PQ) core holes which were completed between July 26, 2022, and September 12, 2022. The drill holes were located at eight different drill sites for a total of 1,138 meters at the Doby George deposit (see Figure 1 and Table 2 below).


The purpose of the Phase 1 drill program was to evaluate areas within, and adjacent to, the current resource boundary to:

  • validate and delineate current mineral resources;
  • locally assess for the expansion potential and structural controls on mineralization;
  • provide samples for metallurgical test work to outline leach kinematics, as well as mineralized material and waste rock characteristics; and
  • expand upon geotechnical studies through additional test work.

Hole DGC791 was completed in the West Ridge resource area of Doby George, which accounts for approximately 82% of the current mineral resource estimate at Doby George. Holes DGC792 and DGC793 were drilled in the Daylight deposit area of Doby George. All three drill holes showed very positive FA grade distribution when compared to the resource block model prepared for the Company by Mine Development Associates and contained in the technical report titled “2021 Updated Resource Estimates and Technical Report For the Aura Gold-Silver Project, Elko County, Nevada” dated October 20, 2021 (with an effective date of October 14, 2021) (see Figure 2 and Figure 3 below). A copy of the Technical Report is available on SEDAR ( under Western Exploration’s issuer profile. All three West Ridge holes released YTD, including DGC791 in this release, show robust AuCN/AuFA ratios in excess of 90%. Holes DGC792 and DGC793, drilled in the Daylight deposit, show more variable AuCN/AuFA ratios (in line with legacy metallurgical reports) but still average between 71 and 83% for the three reported intervals.


Once assays results have been received for all nine drill holes completed in connection with the Phase 1 drill program, McClelland labs will commence certain heap leach and column leach test work with the previously crushed and assayed samples. The Company expects to receive the results of all metallurgical test work at the start of Q2 2023.


About Doby George


Doby George is one of the highest-grade, undeveloped open pit heap leach resources in Nevada and one of three mineral deposits on Western Exploration’s 100% owned Aura Project. The Aura Project is located 32 kilometers north of the Jerritt Canyon mine, which has been in continual operation since 1981. The deposit is an outcropping, high-grade sediment-hosted mineral deposit, with multiple zones of mineralization identified by drilling in a 1.7 x 0.8 km area (see Figure 4 below). The zone of oxidation extends 150 to 200 meters below surface, while limited deep drilling has encountered unoxidized gold mineralization at depths of over 600 meters below surface.


Homestake Mining Company initially discovered the deposit in the mid-1980s. Since that time, 827 drill holes have been completed, totaling 115,197 meters of drilling. This includes 74 drill holes, totaling 22,622 meters that were drilled by Western Exploration LLC between 1998 and 2017. Metallurgical test work completed on oxidized material by Homestake Mining Company, Independence Mining Company, and Atlas Precious Metals Inc., has indicated favorable metallurgy for standard cyanide heap leach processing. Results from the previous metallurgical testing completed on 52 bottle rolls and 23 column leach samples indicate that heap leach gold recoveries approaching seventy percent can be expected via a crush of 1 to 1.5 inches.


In addition to an established mineral resource estimate (as determined in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects), the Aura Project has well established infrastructure including year-round accessibility by highway and county-maintained road and nearby access to water and electricity (see Figure 5 below). Western Exploration has exploration, development, and mining rights on 930 hectares of privately owned fee lands through a mineral lease agreement with a local landowner and may purchase those fee lands at any time for the development of Doby George.


The 6,000-hectare Aura Project is unique in the junior mining space, as resources have been identified in three different deposits (Doby George, Gravel Creek and Wood Gulch), as supported by the Technical Report (see Table 3 below).

Qualified Person Approval


The scientific and technical content in this news release has been reviewed, prepared and approved by Mark Hawksworth, General Manager of the Western Exploration’s Aura Project, who is a “qualified person” within the meaning of NI 43-101.


Quality Assurance – Quality Control


Drill program design, Quality Assurance/Quality Control and the interpretation of results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices.


Drill core samples were delivered by Major Drilling to Western Exploration’s secure warehouse/logging facility in Mountain City and washed, photographed and logged by company geologists. Quality control (QC) samples are inserted at regular intervals in the sample stream, including blanks, core duplicates and reference materials with all sample shipments to monitor laboratory performance.


Drill core samples are transported by Neilsen Exploration to McClelland Laboratory Inc. located in Sparks, Nevada, for sample preparation and analysis. Each interval is removed from the core box, weighed and crushed using a jaw-crusher to an approximately 2″ top size. The crushed interval is blended by repeated coning and is quartered to obtain a one-quarter split for finer crush. Each one-quarter split is crushed to 10 mesh (2 mm) and split to obtain 0.25 – 0.50 kg for pulverization. For fire assays, the 0.25 kg split is pulverized to >95%-150 mesh (106µm). Analysis for gold and silver is completed using a 30-gram fire assay with AA finish. For the CN soluble tests, A 10-gram aliquot of sample (>95%-106 µm) is leached by shaking in a 50 mL test tube for 1 hour, at ambient temperature and 33.3% solids, using a solution of NaCN (5.0 gpL) and pH > 11.0 using NaOH. The solution is separated by centrifuging. Clear solution is analyzed by AA for gold.
