Easy Creek Results
A 1,500 meter x 1,000 meter gold-in-soil anomaly (20 ppb to 1,610 ppb gold) +/- copper +/- molybdenum has also been identified at the northern end of the Milkbone Fault at the Easy Creek prospect. Highlight assay results include:
1.3 g/t Au and 0.9 g/t Au/0.92% Cu in individual grab rock samples*
Gold-in-soil values ranging from 70 ppb to 1,000 ppb (1 g/t Au) within a 350-meter diameter area surrounding a biotitic quartz-diorite intrusive with coincident copper-in-soil values ranging from 272 ppm to 1,805 ppm (0.18% Cu)
High-Grade Ag-Au Vein Field Results (DC Prospect)
New high-grade gold and silver assays are reported for veins at the western end of the High-Grade Ag-Au Vein field at the DC Prospect, expanding it to more than 1,000 meters in length, including:
1,500 g/t Ag and 4.1 g/t Au in a grab rock sample*
7.9 g/t Au and 94 g/t Ag over 1.4 m in a rock chip channel sample
*Note – grab samples by their nature are selective and not necessarily representative of the mineralization hosted on the property.
“We are extremely pleased with the regional picture emerging at Johnson Tract with recent surface exploration results now defining widespread, robust and diverse styles of mineralization over an area several square kilometres in size,” commented President and CEO Darwin Green. “We are looking forward to drill testing several of these new prospects for the first time in our upcoming 2021 field season while also methodically expanding our high-grade JT Deposit cornerstone resource (750koz at 10.9 g/t AuEq Indicated).”
2020 Surface Exploration Program
Concurrent with the 16,418 meter/32 drill hole program completed in the JT Deposit area, the Company carried out a regional exploration program designed to evaluate prospects on the surrounding district-scale 21,000-acre property. The work included reconnaissance-level geological mapping, prospecting and geochemical sampling to evaluate historic showings and to explore for new zones of mineralization. Rock sampling and contour soil sample lines were collected along with Induced Polarization geophysical surveys at the DC and Kona prospects.
Results from rock and soil sample locations are shown on Figure 1 and Figure 2. Results from other regional prospects will be presented at a later date pending receipt of additional assay data.
Discussion of Results and Regional Gold-Bearing Structure
The Milkbone Fault is a 6 km long north-south fault that may represent an important regional gold-bearing structure in the northern portion of the Johnson Tract project. It is separate and distinct from the main JT Deposit area located several kilometers to the southwest.
The Milkbone Fault dips steeply to the west and in the Milkbone Prospect area places fresh andesite on the east side against silicified pyritized dacitic tuff on the west side. Rock sampling of sub-angular float encountered while soil sampling across the surface trace of the fault at the Milkbone Prospect returned up to 184 g/t Au, 46 g/t Ag, 20% Pb, and 2.1% Zn. Sampling of the adjacent silicified pyritized host rock returned 1.03 g/t Au and 1% Pb. The east-west contour soil line over the trace of Milkbone Fault returned gold-in-soil values ranging from 70 ppb to 4,390 ppb (4.39 g/t Au) over a 150-meter wide zone. The Milkbone Prospect soil anomaly is located 400m west of the western limit of the new +1000 long High-Grade Ag-Au Vein Field discovered at the DC Prospect.
The Milkbone Fault can be traced four kilometers northwards to the Easy Creek Prospect where recent contour soil sampling has identified a broad 1,500-meter x 1,000-meter gold-in-soil anomaly (20 ppb to 1610 ppb Au) and local elevated copper and molybdenum. A cluster of very high values was returned from a 350-meter diameter area circling a biotitic quartz-diorite intrusive, where 33 soil samples range from 70 ppb to 1000 ppb gold (average = 273 ppb Au). Overlapping copper-in-soil values range from 272 ppm to 1,805 ppm (0.18% Cu). Rock sampling along the soil lines returned highs of 1.3 g/t Au and 0.9 g/t Au/0.92% Cu in individual grab rock samples.
The soil anomalies at the Milkbone and Easy Creek Prospects are open to expansion and will be a focus of additional follow-up during the upcoming 2021 field season. Along with the recently defined +1000m long Ag-Au Vein Field at the DC Prospect, multiple promising new targets have been identified for future discovery focused drilling.
The Company continues to process incoming data from the 2020 field season, including the inversion of DCIP geophysical data collected from the DC and Kona Prospects and additional rock sample data.
About the Johnson Tract Gold Project
Johnson Tract is a poly-metallic (gold, copper, zinc, silver, lead) project located near tidewater, 125 miles (200 kilometers) southwest of Anchorage, Alaska, USA. The 21,000-acre property includes the high-grade Johnson Tract Deposit (“JT Deposit”) and at least nine (9) other mineral prospects over a 12-kilometer strike length. HighGold acquired the Project through a lease agreement with Cook Inlet Region, Inc. (“CIRI”), one of 12 land-based Alaska Native regional corporations created by the Alaska Native Claims Settlement Act of 1971. CIRI is owned by more than 9,100 shareholders who are primarily of Alaska Native descent.
Mineralization at Johnson Tract occurs in Jurassic-age intermediate volcaniclastic rocks and is characterized as epithermal-type with submarine volcanogenic attributes. The JT Deposit is a thick, steeply dipping silicified body (20m to 50m average true thickness) that contains a stockwork of quartz-sulphide veinlets and brecciation, cutting through and surrounded by a widespread zone of anhydrite alteration. The Footwall Copper Zone is located structurally and stratigraphically below JT Deposit and is characterized by copper-silver rich mineralization.
The JT Deposit hosts an Indicated Resource of 2.14 Mt grading 10.93 g/t gold equivalent (“AuEq”) comprised of 6.07 g/t Au, 5.8 g/t Ag, 0.57% Cu, 0.80% Pb and 5.85% Zn. The Inferred Resource of 0.58 Mt grading 7.16 g/t AuEq is comprised of 2.05 g/t Au, 8.7 g/t Ag, 0.54% Cu, 0.33% Pb, and 6.67% Zn. For additional details see NI 43-101 Technical Report titled “Initial Mineral Resource Estimate for the Johnson Tract Project, Alaska” dated June 15, 2020 authored by James N. Gray, P.Geo of Advantage Geoservices Ltd and Brodie A. Sutherland, P.Geo. Gold Equivalent is based on assumed metal prices and 100% recovery and payabilities for Au, Ag, Cu, Pb, and Zn. Assumed metal prices for the Resource are US$1350/oz for gold (Au), US$16/oz for silver (Ag), US$2.80/lb for copper (Cu), US$1.00/lb for lead (Pb), and US$1.20/lb for zinc (Zn) and are based on nominal 3-year trailing averages as of April 1, 2020. Historical metallurgical testing on drill core samples has indicated that good gold and base metal recoveries and marketable concentrates can be expected. Prior to HighGold, the Project was last explored in the mid-1990s by a mid-tier mining company that evaluated direct shipping material from Johnson to the Premier Mill near Stewart, British Columbia.
