E79 Resources Drills 11 meters of 160.46 g/t Au at Happy

4 min read


E79 Resources Corp. (ESNR.V) has released initial assay results received from the first two drill holes (April 27, 2021) at its Happy Valley gold prospect on its Myrtleford property in Victoria, Australia.

Drilling highlights

Drill hole HVD002


  • 0.70 metre at 99 grams per tonne gold from 94.90 m downhole.


Drill hole HVD003


  • 0.60 m at 147 g/t Au from 165.20 m downhole;
  • 11.10 m at 160.45 g/t Au from 190.40 m downhole, including:
    • 0.60 m at 2,430 g/t Au from 190.40 m;
    • Three m at 126 g/t Au from 198.50 m.


Rory Quinn, E79’s president and chief executive officer, stated: “Our drill program at Happy Valley was designed to test for down-dip extensions of previously mined high-grade (approximately 31 g/t Au) quartz vein structures. The first two drill holes at Happy Valley confirm extension of mineralized structures substantially below known historic mining levels. HVD002 intersecting gold roughly 60 m beneath known historic mining and HVD003 intersecting gold roughly 80 m below that.

“Confirmation of a section of visible gold assaying at over 78 ounces per tonne (2,430 g/t Au) demonstrates the high-grade potential of the Victorian goldfields. The presence of four other intersections assaying greater than three ounces per tonne demonstrates this is not a one-hit wonder at Happy Valley. Happy Valley sits within an approximately seven-kilometre corridor of historic gold mines at Myrtleford and that is one of five distinct corridors of historic gold mines observed on our Myrtleford property.”

Remaining results for HVD002 and HVD003, and initial results for HVD004 and HVD005 are pending.

Analytical assay results have confirmed the tenor of visible gold and other mineralized zones identified in drill core from the first two diamond drill holes at the Happy Valley prospect. These results confirm the company’s belief that high-grade gold mineralization exists at depth below historic gold mining areas. The current program will generate structural, lithological, alteration and geochemical information to determine their relationship to gold mineralization at the Happy Valley mining centre. This information will provide a model for exploration along strike and broader model for the company’s Myrtleford prospects.

Happy Valley gold prospect

The Happy Valley Prospect is situated in the south eastern portion of the company’s exploration licence EL006724 in Victoria, Australia. It lies within a seven-kilometre-long trend of historical workings. The Happy Valley mining centre has a documented historical production of 34,200 ounces of gold predominantly between 1866 to 1875. The Happy Valley mining centre produced at an average grade of approximately 31 g/t Au, which presents E79 with an extremely attractive target. To date, only limited modern exploration has been conducted at this prospect.

Gold mineralization at Happy Valley occurs as quartz infill fractures and spurry formations within carbonate altered sedimentary units of lower Ordovician age (448 million years to 443 million years). Regionally mineralization appears to be proximal and related to the emplacement of several major regional Devonian-age granitic plutons. The gold can occur as free particles within the quartz veins and can also be associated with sulphides, including pyrite and to lesser degrees arsenopyrite and galena.

Drill hole HDV003 was drilled at a dip of negative 55 degrees, (16 degrees steeper than HVD002), and on the same azimuth as HVD002 (216 degrees mag, 228 degrees grid). The drill hole has intersected two zones of quartz containing both sulphides and coarse gold. All intersections represent downhole lengths and as such do not represent true width intersections. Historic mining operations were undertaken on subvertical steeply dipping quartz vein structures.

All samples are one-half HQ diameter (63.5 millimetres) diamond drill core. Sampling was conducted to geological contacts. Samples were shipped by E79 contractors to ALS Global in Orange, New South Wales, Australia, by DHL. The samples were crushed to a nominal 85 per cent passing 3.15 mm. A one-kilogram split was obtained using a Boyd rotary splitter and pulverized in its entirety to a nominal 85 per cent less than 75 mm. A quartz wash was run through both the crushing and pulverizing equipment between all samples, and sizing tests were performed on both the coarse crush and pulverized material. All samples were analyzed by 50-gram fire assay with an atomic absorption finish (Au-AA26). This method has an upper detection limit of 100 parts per million. All samples were also analyzed by a second fire assay using a reduced charge weight with an upper detection limit of 10,000 ppm (Au-OR1). Approximately 50 per cent of the samples were analyzed by three separate overrange fire assays to confirm reproducibility of the results. Overrange values from Au-AA26 were also rerun following dilution. Four certified reference materials (CRM) and nine coarse quartz blanks were also submitted with the samples to monitor accuracy and possible cross contamination, respectively. The results for all quality control samples lie within acceptable limits.

Next steps


  • Reviewing follow-up drilling to expand on results once all other assays have been received;
  • Assessment of geological and structural data collection, assessment of hydrothermal alteration to aid in defining new target areas;
  • The company continues to apply observations from the initial results to develop a comprehensive structural model for the Happy Valley target area;
  • A permit-wide review and reprocessing of geophysical data from the Myrtleford exploration licence to define additional targets.

About E79 Resources Corp.

E79 Resources is focused on exploring for Fosterville-type mineralization at its Beaufort and Myrtleford properties in the Victorian goldfields, Australia. At Beaufort, an opportunity exists to explore for a hard rock source of a major alluvial goldfield along a structure that is known to host gold in the region. The Myrtleford property represents the consolidation of an entire historic gold camp with over 70 past-producing gold mines on the property, where the bulk of historic mining stopped at the water table.
