VANCOUVER, BC / ACCESSWIRE / May 10, 2021 / Doubleview Gold Corp ("Doubleview", the "Company") (TSXV:DBG) (OTC PINK:DBLVF) (FRANKFURT:1D4) is pleased to announce excellent results from its initial metallurgical tests on materials from its 100% owned Hat Copper-Gold-Cobalt deposit, located in the Golden Triangle region of Atlin Mining District in Northwest British Columbia. The initial metallurgical extraction studies were designed to evaluate the characteristics of mineralization and the potential recoverability of component metals. In particular, attention was directed to Cobalt, an increasingly valuable and sought-after commodity that only in recent years has become a potentially important economic contributor to Hat resources.

For testing purposes, a composite sample, compiled from selected drill core analytical sample pulps, was processed by crushing and grinding and then divided into two sub-samples: "Gravity" and "Composite". "Composite" went directly to flotation, "Gravity" was gravity separated to remove free gold and the samples were each subjected to the same flotation sequence to produce a high gold-copper concentrate with low cobalt and a pyrite concentrate with high cobalt. Recoveries are shown in the accompanying table:

HAT Flotation Results - Indicated grades and Recoveries

	Metal	Grade		Recovery(%)
Sample		Gravity Tails	Composite	Gravity Tails	Composite
Head
	Cu (%)	0.2	0.21
	Co(ppm)	132	131
	Au(g/t)	0.36	0.32
Gravity Concentrate
	Au(g/t)	11		11
Copper Concentrate
	Cu (%)	27	14	81	76
	Co(ppm)	470	1160	19	26
	Au(g/t)	7	12	54	64
Pyrite Concentrate
	Cu (%)	0.1	0.1	5	6
	Co(ppm)	2620	2530	49	48
	Au(g/t)	3	3	21	23
Combined Concentrates
	Cu (%)			86	82
	Co(ppm)			68	74
	Au(g/t)			86	87

The initial flotation tests demonstrate that it is possible to produce a high gold, low cobalt-copper concentrate and a high cobalt, low gold pyrite concentrate. Further optimization work will aim to improve selectivity, grades and recoveries.

Additional mineral samples have been submitted for QEMSCAN ("Quantitative Evaluation of Minerals by Scanning Electron Microscopy") to better understand the mineralization of Hat polymetallic deposit and the nature of flotation tails losses, these results will be announced in due course.

Metallurgical investigations have been conducted by Sepro Mineral Systems, Sepro Laboratories Inc. of Langley, B. C., under the supervision and guidance of EUR ING Andrew Carter, B.Sc. CEng. MIMMM, MSAIMM, SME, Technical Director of Coffey, a Tetra Tech Company. Tetra Tech provides metallurgical consulting and development services to the resources sector and the extractive mineral and metallurgical industries.

Mr. Farshad Shirvani, President and CEO of Doubleview Gold Corp., states that "I am pleased with the exceptional initial metallurgical results from the Hat Polymetallic Deposit recovery test work. The newly received data is especially timely as copper, gold and cobalt prices are close to all-time high levels. Market demand for these and other metals, including nickel, palladium and scandium, critical to the rapidly expanding and evolving alternative energy and automotive industries, appears to have almost unlimited upside as worldwide decarbonization efforts gain momentum. The Hat deposit has such potential to contribute to Canada's future as it is poised, and is morphing into, what I believe a Saudi Arabia of strategic metals."
