HIGHGOLD MINING REPORTS ENCOURAGING RESULTS FROM ONTARIO DRILL PROGRAM
Highgold Mining Inc. has released positive drill results from the first half of the 2020 drill program on its gold projects located in the Timmins gold camp, Ontario. Twelve drill holes for 2,524 metres of diamond drilling were completed at the Munro-Croesus and Golden Mile properties prior to the program being suspended due to COVID-19 restrictions. The company intends to complete the remaining 2,500 metres of planned drilling later this year.
- Croesus-like vein intersected 80 metres southeast of the shaft returning 29.1 grams per tonne gold over 0.30 m at a downhole depth of 90.7 metres in hole MC20-33.
- The observed vein in MC20-33 was 30 metres downdip of historic drill intersections of 76.42 g/t Au over 0.10 m and 69.59 g/t Au over 0.15 m that collectively define a well-mineralized vein structure with similar orientation to the main Croesus vein located on the north side of the Croesus fault.
- Hole MC20-33 is the only completed and sampled hole of the 2020 program to have tested this vein structure, which may represent the fault offset equivalent of the mined out Croesus vein. Future drilling will test areas where this vein has the potential to expand into wider, bonanza-grade type mineralization for which the mine was known.
- Two of the six holes completed at Munro-Croesus were unable to be logged or sampled prior to the COVID-19 shutdown; this work will be completed when it is practical to do so.
Golden Perimeter highlights:
- Reconnaissance-style drilling at the company's first exploration program at Golden Perimeter has identified widespread gold mineralization over an 850-metre-long trend consisting of gold-plus-or-minus-silver-bearing quartz veins in a variable altered and pyritic monzonite intrusion, including:
- 10.30 g/t Au and 42.80 g/t Ag over 0.2 m;
- 2.30 g/t Au over 0.9 m;
- 0.50 g/t Au over 4.7 m;
- 4.04 g/t Au over 0.3 m;
- 4.82 g/t Au and 57.50 g/t Ag over 0.3 m.
"We are encouraged by the intersection of high-grade gold in stepout drilling at Munro-Croesus," said Highgold president and chief executive officer Darwin Green. "This shows the persistence of the gold-bearing system away from the historic workings and supports our working theory for the environment in which the Croesus-type mineralization was generated. We look forward to continued testing of this and other high-quality targets on the property when we complete the remainder of our planned program later this year."
The planned program called for a minimum of 5,000 metres of diamond drilling with two drill rigs divided between the company's Munro-Croesus, Golden Perimeter and Golden Mile properties. Half of the program was completed prior to the early suspension in mid-March, including:
- Completion of all planned drill metres at the Golden Perimeter property;
- Completion of one-third of planned drill meters at the Munro Croesus property;
- None of the planned drill metres at the Golden Mile property.
The Munro-Croesus property is situated immediately north of the regional-scale Porcupine-Destor and Pipestone fault zones. Historical mining on the property focused on very high-grade gold mineralization associated with a shallow, north-south-trending quartz vein hosted by a brecciated pillowed mafic volcanic. Diamond drilling in 2011 by the previous owners intersected 18.79 g/t Au over 4.1 metres in the hangingwall to the mined Croesus vein and recent geological interpretative work by Highgold indicates there may be an opportunity to identify unmined portions of the historic Croesus vein within close proximity of surface, including potential offsets. In addition, multiple parallel veins have been mapped across the property, the majority of which have never been tested due to limited exploration drilling outside the historic mine environment.
A total of six drill holes totalling 971 metres tested the northwest and southeast strike extensions of the mapped Croesus flow away from the historic Croesus shaft area. All holes intersected the Croesus flow as expected with hole MC20-33, collared 140 metres to the southeast of the shaft, returning 29.1 g/t Au over 0.30 m at a downhole depth of 90.7 to 91.0 m. The intercept is hosted within pillowed mafic flow with 20 per cent quartz-carbonate veining and 15 per cent arsenopyrite and may represent a faulted offset to the main Croesus vein. Hole MC20-33 is the only completed and sampled hole of the 2020 program to have tested this vein. Historic drilling 30 metres updip on the same vein returned 76.42 g/t Au over 0.10 m in hole MC08-08 and 69.59 g/t Au over 0.15 m in hole CG77-32. The final two drill holes of the program (MC20-34 and 35) remain unlogged and unsampled due to the rapid shutdown of this program due to COVID-19.
Golden Perimeter property
The Golden Perimeter property is located south of Timmins on the south and southeast edges of the Shaw dome geological structure. The planned program targeted areas of historical 1980s-era drilling, new airborne magnetic and ground induced polarization (IP) geophysical anomalies, and an extensive monzonite for potential intrusive-related gold prospects. The intrusive bodies are hosted within mafic and ultramafic volcanics of the Tisdale group, the same geological formation that hosts the majority of the shear-hosted gold mineralization within the main Timmins gold camp.
Five drill holes and one partial drill hole totalling 1,553 metres were completed across the various targets. Four of the holes designed to test an elongated intrusive target over an 850-metre strike length intersected gold-plus-or-minus-silver-bearing quartz veins in a variable altered and pyritic monzonite intrusion. A complete list of significant assay intersections for Golden Perimeter can be found in the associated table.
About Highgold's Timmins properties
Highgold owns (or has the option to own) 100 per cent of each of its three Timmins properties. The Munro-Croesus gold project is located approximately 75 kilometres (47 miles) east of Timmins, is proximal to the Porcupine-Destor and Pipestone faults, and located approximately three kilometres (1.9 miles) northwest and along trend of Pan American Silver's multimillion-ounce Fenn-Gib gold deposit. Mining occurred intermittently at Munro-Croesus between 1915 and 1936. The Golden Mile 86-square-kilometre (33 square miles) property is located nine kilometres (5.6 miles) northeast of Newmont's multimillion-ounce Hoyle Pond deposit in Timmins. The Golden Perimeter properties (two blocks) are located to the south and southeast of Timmins on the south and southeast edges of the Shaw dome geological structure.

Quality control and quality assurance
Ian Cunningham-Dunlop, PEng, vice-president, exploration, for Highgold Mining and a qualified person (QP) as defined by Canadian National Instrument 43-101, has reviewed and approved the technical information contained in this release.
Samples of drill core were cut by a diamond blade rock saw, with half of the cut core placed in individual sealed polyurethane bags and half placed back in the original core box for permanent storage. Sample lengths typically vary from a minimum 0.2-metre interval to a maximum 1.5-metre interval, with an average 0.5-to-1.0-metre sample length. Drill core samples were delivered by truck in sealed woven plastic bags to ALS Geochemistry laboratory facility in Timmins, Ont., for sample preparation with final analysis at ALS Geochemistry Analytical Lab facility in North Vancouver, B.C. ALS Geochemistry operate meeting all requirements of international standards ISO/IEC 17025:2017 and ISO 9001:2015. Gold was determined by fire assay fusion of a 50 g subsample with atomic absorption spectroscopy (AAS). Various metals including silver, gold, copper, lead and zinc are analyzed by inductively coupled plasma (ICP) atomic emission spectroscopy, following multiacid digestion. The following company-wide analytical protocols are in place for samples with base and precious metal values that exceed certain thresholds. Samples returning values greater than 100 parts per million gold from fire assay and AAS (atomic absorption spectroscopy) are determined by using fire assay and a gravimetric finish. Samples with visible gold or suspected of having exceptionally high grade are submitted for metallic screen gold analysis on a larger subsample. The elements copper, lead and zinc are determined by ore-grade assay for samples that return values greater than 10,000 ppm by ICP (inductively coupled plasma) analysis. Silver is determined by ore-grade assay for samples that return greater than 100 ppm.
