TORONTO, July 11, 2022 (GLOBE NEWSWIRE) — EnviroGold Global Limited (CSE: NVRO | OTCQB: ESGLF |FSE: YGK) (“EnviroGold Global” or the “Company“), a Clean Technology Company accelerating the world’s transition to a circular-resource economy through the production of Metals Without Mining, is pleased to provide an update on the status of its Hellyer and Buchans Tailings reprocessing projects and its global tailings reprocessing pipeline.

Hellyer Tailings Reprocessing Project – 2022 Progress

In August of 2020, EnviroGold Global executed a commercial agreement to undertake feasibility and metal recovery studies at the Hellyer Gold Mine tailings in Tasmania, Australia. The Hellyer tailings are comprised of refractory, polymetallic, volcanogenic massive sulfide (VMS) mineralized material produced as a by-product of underground mining operations at the Hellyer Gold Mine.

During its life, the Hellyer Mine produced 15 million tonnes of ore and yielded 601,000 tonnes of bulk concentrate, 2.7 million tonnes of zinc concentrate, and 728,000 tonnes of lead concentrate. Due to the refractory nature of the Hellyer VMS ore, initial data indicate that 95% of the gold and 67% of the silver remains unrecovered within the tailings. A historical (2020) JORC resource report indicated that the Heller Tailings contain 634k oz gold, 22.9M oz silver and 419k tonnes copper-lead-zinc with grades of 2.60 g/t Au, 94 g/t Ag, 2.33% Zn, 3.01% Pb and 0.19% Cu contained in 6.37Mt of Measured & Indicated, and 1.21Mt of Inferred Resources. EnviroGold Global expects further quantities of precious, critical, and strategic metals will be found within other tailings within Hellyer Gold Mine’s permitted operational area.

In 2021, following extensive technical development with Core Resources of Brisbane, Australia, the Company announced the development of a proprietary flowsheet for the Hellyer tailings, with 3rd part data (Core Resources) indicating strong recoveries of the substantial precious metals within the Hellyer Tailings (~59% gold, ~90% silver).

In February of 2022, the Company announced the execution of a binding definitive agreement with Hellyer Gold Mines, granting EnviroGold Global the rights to reprocess the Hellyer tailings and recover the valuable metals subject to a profit-sharing agreement entitling EnviroGold Global to 50% of the pre-tax profits up to $24M per year and 65% of the pre-tax profits thereafter.

Additional significant milestones achieved for the Hellyer Project in 2022 include flowsheet optimization program undertaken with Core Resources that yielded substantial increases in recoveries of gold (from ~59% to ~80%) from the Hellyer Tailings, the announcement of an MOU with Sedgman as a project partner, and the commencement of substantive negotiations for Hellyer project financing. The Company continues to advance the project towards commercial metal production with initial pilot-scale metal production planned for 2022.

Buchans River Tailings Reprocessing and Rehabilitation Project – 2022 Progress

In September of 2021, EnviroGold Global announced the execution of definitive, binding agreements adding the Buchans River Delta Tailings Reprocessing and Rehabilitation Project to the Company’s global tailings reprocessing portfolio. Five historic mines operated around the upriver town of Buchans over 56 years from 1928 through 1984, extracting barite, zinc, lead, copper, gold, and silver. These mines produced over 16 million tonnes of ore with an average mill head grade of 14.51% Zn, 7.56% Pb, 1.33% Cu, 126 g/t Ag and 1.37 g/t Au.

For about 35 years (1928 to 1964), tailings from these operations were discharged directly into the Buchans River, flowing downstream and settling into the delta at Beothuk Lake, resulting in the deltaic tailings deposit. Some of these tailings are exposed without water cover, and their physical and chemical properties cause heavy metal leaching into the lake water, which is salmon habitat.

In its initial qualification of the resource at the Buchans River Delta, EnviroGold Global leveraged extensive historical and exploration data for the site, including historical production data of the mines in Buchans, the technologies in use through their operating lives (and expected recovery rates), and three assessments conducted between 1989 and 2005 by the government of Newfoundland and Labrador, Bolero Development Corporation, and Geologist John Tuach. These studies indicated there are significant amounts of base and precious metals in approximately 2 million tonnes of tailings in the well-studied central claim. EnviroGold Global expects further exploration in unexamined claims to indicate an extension to this tonnage. Of the more than 16 million tonnes of tailings produced over the life of the Buchans Mines, 2 million tonnes were placed in tailings ponds, and 2 million tonnes have been identified in the central claim, leaving ~12MM tonnes of tailings yet to be identified.

In order to identify undiscovered tailings resource in the Delta, in 2021, EnviroGold Global completed a ground-penetrating radar study covering 8,807,294 m3. Preliminary results indicated the potential presence of additional tailings when compared to the previous studies.. The data indicated potential mineralized material extending into the Jeff Wall claim, forming a “Western Arc” over a 1 km strike length.

Subsequent to the geophysical survey, EnviroGold Global completed a coring program to collect the identified material from the Jeff Wall claim. During initial exploratory coring in 2Q2022, the Company successfully recovered material from several points within the Jeff Wall Claim, validating the coring methodology, confirming the presence of tailings, and positioning the Company to commence advanced exploration of the claims following initial metal production at the Company’s Hellyer Tailings Project.

Global Tailings Project Pipeline – 2022 Progress

The Company has advanced commercial negotiations with the owners of additional tailings project opportunities, including two major projects in North America. The Company expects to announce the execution of at least one additional commercial agreement for a major tailings project in 2022.

Commenting on the Company’s progress to date, EnviroGold Global CEO, Dr. Mark Thorpe, said, “The milestones achieved to date are a reflection of the talent and capability of our world-class team and our laser focus on producing Metals Without Mining. We remain confident in our ability to establish circular-economy market leadership in the metals and mining sector as we continue to build a high value project pipeline and advance towards initial metal production at the Heller Tailings Project.”

Additional Information on the Hellyer TSF Tailings Historical Estimate

The Hellyer TSF tailings have been extensively studied by EnviroGold Global and HGM. A “historical estimate” was completed in November 2020 in accordance with the JORC Code (2012) for the Hellyer TSF tailings for NQ Minerals Plc (“NQM”), the parent company of HGM. This historical estimate was completed by independent mining consultants CSA Global (UK) Limited and reported in a JORC Competent Persons Report (NQM, 2020), which can be sourced from NQM’s corporate website (see link below). The Hellyer TSF historical estimate reported 6.37 Mt of Measured and Indicated Mineral Resources and 1.21 Mt of Inferred Mineral Resources with gross metal grades of 2.60 g/t Au94 g/t Ag2.33% Zn3.01% Pb and 0.19% Cu (Table 1).

Historical Estimate Notes:

  • The Hellyer TSF historical estimate was completed in accordance with the 2012 Australasian Joint Ore Reserves Committee Code (“JORC 2012 Code”) and reported in a JORC Competent Persons Report for NQM dated November 11, 2020 for the “Hellyer Tailings Retreatment Project, Tasmania” (link to source:
  • No lower cut-off reporting grade was applied.
  • Metal tonnages and ounces rounded from calculated values. Gross metal grades include 2.60 g/t Au, 94 g/t Ag, 2.33% Zn, 3.01% Pb and 0.19% Cu.

This historical estimate is considered relevant as it appears to demonstrate the potential tonnages and grades and reasonable prospects for eventual economic extraction for the Hellyer TSF tailings. However, EnviroGold Global cautions readers that this historical estimate was not completed using 2014 CIM Definition Standards on Mineral Resources and Reserves and is not supported by a technical report completed in accordance with National Instrument 43-101 (“NI 43-101”). In addition, under the JORC (2012) Code standards, Measured, Indicated, and Inferred mineral resource tonnages can be combined, which is not permitted under NI 43-101. A Qualified Person (“QP”) has not done sufficient work to classify this historical estimate as current mineral resources and EnviroGold Global is not treating this historical estimate as current mineral resources. A significant amount of work is required to verify the historical estimate as current resources including: (1) upgrading the geological model with any additional drilling data and mining depletions on the tailings since the historical estimate was completed, (2) a QP completing a full data verification of historical drill hole sampling procedures, analytical results, and metallurgical test results, and (3) additional bench-scale and field metallurgical test work to determine reprocessing and recovery characteristics using EnviroGold Global’s proprietary tailings reprocessing technology. EnviroGold Global is not aware of any additional historical estimates for the Hellyer TSF tailings.
