HighGold Mining Inc. (TSXV:HIGH, OTCQX:HGGOF) has received high-grade results from the ongoing 2021 drill programme at its 0.75 Moz Indicated 10.9 g/t gold equivalent Johnson Tract polymetallic Gold Project Southcentral Alaska, USA.
Infill hole JT21-125 was designed with the dual purpose of collecting material to support a Phase I metallurgical testing programme and to provide better definition of the deeper, higher-grade portion of the JT Deposit.
President and CEO, Darwin Green, said the hole successfully intersected a long interval of gold-dominant mineralisation with significantly higher gold grade than the average of the JT Deposit resource. True thickness of the JT Deposit typically ranges from 20 to 50m and in the JT21-125 intersection is over 35m
Drill Highlights Hole JT21-125
- 18.69 g/t Au, 2.43% Zn, 0.47% Cu over 56.6m, including
- 31.69 g/t Au, 1.82% Zn, 0.58% Cu over 32.9m, including two high-grade intervals of
- 64.74 g/t Au, 1.49% Zn, 0.53% Cu over 5.0m and
- 114.37 g/t Au, 3.51% Zn, 0.33% Cu over 4.9m
“We are very pleased to report this new intercept from the deeper reaches of the JT Deposit that confirms the strength of the mineralizing system,” Mr Green said. “In combination with the recent drill results from the DC Prospect 4km to the northeast, the Johnson Tract Project continues to establish itself as one of the pre-eminent high-grade gold exploration projects located in the USA.”
021 Phase I Metallurgical Testing Programme
Blue Coast Metallurgy & Research has been engaged to carry out a Phase I metallurgical testwork programme on the JT Deposit using selected drill core from the 2021 drill programme. The Programme will: a) complete test work to confirm historic metallurgical results reported by previous operators and identify possible opportunities for improvement; and b) advance the metallurgy to support potential future PEA-level process design.
The Programme will include QEMSCAN mineralogical studies, identification of potential geometallurgical domains, grindability/gravity/flotation test work, and the development of a flowsheet for recovery of pay metals to marketable end products.
Two composites are currently being considered from the upper and lower JT Deposit domains, and potentially a third composite from the Footwall Copper Zone (FWCZ). Drill hole JT21-125 reported in this news release is from the lower JT Deposit domain, located at a deeper level within the deposit.
Current Exploration Activities
Three diamond drill rigs are currently operating on the Project in concert with a regional geological mapping and geochemical sampling programme, air and ground-based geophysical surveying, and a Phase I metallurgical sampling programme. The current phase of drilling is scheduled to conclude on or before month end. Assays results will be released on an ongoing basis pending review and meeting company quality assurance-quality control protocols.
An updated mineral resource estimate is planned for the JT Deposit in early 2022, following the completion and receipt of all assays from the 2021 drill programme. The new resource estimate will incorporate new drilling completed in 2020 and 2021. Over 30,000 meters have been drilled on the Project since the maiden resource.
