The Company recently released drill results from the Company’s first hole, DC21-010, at Difficult Creek which included 578 g/t Au and 2,023 g/t Ag over 6.4m (See Company press release dated October 6th, 2021). Results reported today include five (5) holes completed at Middle DC and the first hole reported from the Upper DC target – note all holes completed at the DC Prospect in 2021 were part of an initial scout drill program and did not include any follow-up drilling.
DC Drill Highlights
11.43 g/t Au, 25.3 g/t Ag, 1.46% Zn, 0.54% Cu over 2.30m within 4.93 g/t Au, 15.5 g/t Ag, 0.24% Cu over 5.8m, in hole DC21-011 located down-dip of DC21-010 at Middle DC
12.92% Zn, 0.67 g/t Au over 2.10m within 4.23% Zn, 0.52 g/t Au over 9.8m, in hole DC21-013 within a northeast trending fault structure
Broad zones of lower grade gold and base metal mineralization intersected in recconaissance drilling 140m to the northwest of DC21-010, consisting of 91.7m grading 0.17 g/t Au, 0.75% Zn in hole DC21-015, including 10.50m grading 0.46 g/t Au, 1.20% Zn; this mineralization is blind at surface beneath relatively unaltered cover rocks, highlighting the potential under cover elsewhere along trend
110 g/t Ag over 1.10m and 5.18 g/t Au, 4.04% Zn over 0.60m in seperate veins interesected in DC21-016, the first hole to test the Upper DC Vien Field
"The 17-hole drill program across the DC Prospect was designed as a first-pass test of multiple targets," commented President and CEO Darwin Green. "With seven of 17 holes reported to date, the Middle DC area has emerged as a zone of significant mineralization with excellent potential to expand. Particularly encouraging is recognition that mineralization appears to be preferentially developed within dacite fragmental volcanic rocks – the same rocks that host the JT Deposit. Significantly, this horizon defines a 1.2km long prospective corridor between the Middle DC and Milkbone targets that is largely obscured beneath overlying (less mineralized) andesitic volcanic cap rocks. We are impressed with the overall scale of the 1.5 km x 3.0 km DC system, the similarities to the JT Deposit located 4km to the southwest, and our predictive exploration model that enhances our chances for ongoing exploration success. With approximately $26 million in working capital, the Company is fully funded to explore this exciting new target area while at the same time continuing the systematic expansion and advancement of the main JT Deposit situated 4km to the southwest."
Discussion of DC Prospect Area Drilling and Geology
A total of 16,198 meters (44 drill holes) were completed during the 2021 exploration program at the greater Johnson Tract project split between deposit expansion and regional prospect drilling. Of this total, 5,285 meters (17 holes) were completed at the DC prospect.
The program at the DC Prospect was designed as a first-pass test of multiple targets across the DC prospect area. Results reported today include six (6) additional holes at the Middle DC and Upper DC areas. The first 7 of 17 holes have now been reported with mineralization successfully intersected in all holes, consisting of high to very high-grade gold and silver intercepts as well as broad intervals of lower grade gold associated with significant base metal mineralization. Assay highlights are shown in Table 1 and the location of drill holes shown on a plan map and cross-section in Figures 1 and 2.
The DC Prospect is located four (4) kilometers northeast of the JT Deposit and is characterized by a series of large gossan alteration zones similar in style to the JT Deposit that collectively extend over a 1.5 km x 3.0 km area. Gold mineralization and pervasive clay +/- anhydrite alteration are preferentially developed within dacitic fragmental rocks that underly a shallowly dipping sequence of lesser altered andesite that is host to a silver and gold-rich vein field at higher elevations. The widespread extent of mineralization exposed in erosional windows through the andesite supports potential for a large and partially blind mineralized system linking the various DC Prospect zones together.
Drill hole DC21-010 was the first hole completed by HighGold at the DC Prospect and targeted the down-dip projection of a showing of mineralized silicified breccia at Middle DC where surface sampling retuned 22.1 g/t Au and 178 g/t Ag over a 1.5m chip sample. Limited drilling in 1983 by a previous operator yielded 3.57 g/t Au, 15.5 g/t Ag, 1.8% Zn over 36.3m in hole DC83-002, including 9.3 g/t Au, 57 g/t Ag and 4.5% Zn over 4.6 meters. Hole DC21-010 intersected the projected mineralized zone at a shallow depth and returned exceptional grades of 577.9 g/t Au and 2,023 g/t Ag over a 6.4m width.
Drill holes DC21-011, DC21-012 and DC21-014 reported today were drilled as steeper holes on the same cross-section as hole DC21-010 at Middle DC. Hole DC21-013 was designed to cross a northeast-trending fault structure, immediately west of the main Middle DC showing. Hole DC21-015 tested a reconnaissance target northwest of Middle DC.
Hole DC21-016 was the first test of the New Vein Field at the Upper DC target identified through geological mapping and sampling in 2020 which returned values up to 1,800 g/t Ag (See Company press release dated February 11, 2021).

Starting azimuth and dip (Azimuth/-Dip) for drill holes reported today are noted as follows: DC21-011 (220/-57), DC21-012 (220/-75), DC21-013 (260/-50), DC21-014 (220/-74), DC21-015 (280/656), and DC21-016 (340/-45). 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 0.5 meter interval to a maximum 2.0 meter interval, with an average 1.0 to 1.5 meter sample length. Drill core samples are shipped by air and transport truck in sealed woven plastic bags to the ALS Global – Geochemistry Analytical Lab in Reno, Nevada, USA for sample preparation and analysis. ALS Global operate according to the guidelines set out in ISO/IEC Guide 25. Gold is determined by fire-assay fusion of a 50 g sub-sample with atomic absorption spectroscopy (AAS). Samples that return values >10 ppm gold from fire assay and AAS are determined by using fire assay and a gravimetric finish. Various metals including silver, gold, copper, lead and zinc are analyzed by inductively-coupled plasma (ICP) atomic emission spectroscopy, following multi-acid digestion. The elements copper, lead and zinc are determined by ore grade assay for samples that return values >10,000 ppm by ICP analysis. Silver is determined by ore grade assay for samples that return >100 ppm.
The Company has a robust QAQC program that includes the insertion of blanks, standards and duplicates.
