EnviroGold Global Limited provided an update on the status of its Hellyer and Buchans Tailings reprocessing projects and its global tailings reprocessing pipeline. 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. 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. 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.

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. 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.

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 Au, 94 g/t Ag, 2.33% Zn, 3.01% Pb and 0.19% Cu.
