EnviroGold Global Files NI 43-101 Technical Report Announcing US$ 350M in net, After-Tax Cash ...

Hellyer Tailings Resource

The estimated total available tailings feed for the Project is about 5.49 Mt of Type 1 tailings, and 3.73 Mt of Type 2 tailings for a total NI 43-101 inferred resource of ~9 Mt (See table). The Mineral Resource estimate is reported in accordance with NI 43-101 Guidelines for current Type 1 and Type 2 tailings and has an effective date of April 30, 2022.

While the resource is presently being reported as an inferred resource for the purposes of this economic study, it is important to note that the Hellyer Tailings Resource has been extensively studied, has been the subject of multiple JORC resource reports (most recently in 2020), each of which included measured, indicated & inferred resources. The Company’s management is confident that the substantial body of work completed on the Hellyer Tailings will facilitate a near-term resource upgrade.

*Expected grades following HGM processing

The homogenised nature of the tailings deposit and the likely mining style (dredging or hydro-mining) largely precludes the ability to apply any cut-off grade which may, in the future, be determined based on project economics. Accordingly, no cut-off grade is used and the stated resource essentially represents the complete tailings accumulation at the reported effective date.

Determining reasonable prospects for eventual economic extraction incorporated the estimated cost for reclaiming, transporting, and processing the reprocessed HGM tailings stream in the NVRO process plant, which is estimated to be approximately US$80 per tonne. Assuming a gold price of US$1,650/oz and a projected gold recovery of 85%, then the break-even cut-off for the mineralization is estimated at 1.51 g/t Au. The tailings mineralization averages a grade of 2.3 g/t Au and is significantly more than the indicative break-even grade as this calculation does not consider the silver and the base metals.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. The QP's are not aware of any known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources.

Mining and Recovery Methods

The initial stages of EnviroGold Global’s NVRO Operations at Hellyer would use a reprocessing plant tailings line from the ongoing Hellyer Gold Mines Pty Ltd. (HGM) processing plant as the source of ZST feed material. This would continue for the period until HGM completes the extraction and milling operations (estimated to be in operation for the next four to six years). Hence, during this period, NVRO operations would not be undertaking any “mining” operations.

During its second operational Phase NVRO would likely perform its own, or sub-contract, tailings recovery work via its own dredging operation (or other recovery method, such as hydro-mining). The current plan during this second phase of NVRO operations would be to acquire (either directly or via a lease) the current HGM dredging, materials handling, and processing plant equipment. For these operations, the existing costs for the HGM operation would be incorporated into the overall costs of the Project.

EnviroGold Global would operate a hydrometallurgical process at Hellyer to re-process tailings from former and current Pb/Zn flotation operations. The initial stages of reprocessing would target the current HGM operations’ ZST as feed to the hydrometallurgical processing plant. The NVRO operations at Hellyer would be undertaken in two stages. The first stage operation would be designed to treat 500 tonnes per day (tpd), with the second stage expansion designed to treat 3,500 tpd, at a nominal throughput rate of 156 tph (dry) and 93.5% availability. The same flowsheet has been used for stage 1, and the stage 2 expansion.

Capital and Operating Costs, and Project Economics

Anticipated total capital cost expenditures (CAPEX) of US$ 92M consist of the initial capital development which includes all costs to develop the property to production, tailings reclamation and processing rate of approximately 500 tpd during Stage 1 and 3,500 tpd for Stage 2. The capital cost estimate was compiled using a combination of database costs from projects developed in Australia and South Africa, scaling factors, and factoring.

Anticipated total operating cost (OPEX) of approximately US$80 per tonne is exclusive of mining and based on combination of metallurgical test work results, experiential judgment, reference to other operating projects with similar processing equipment, and factors as appropriate with a PEA level of study.

The Hellyer Tailings Reprocessing Project is estimated to generate after-tax net cash flows of approximately US$350 million over the anticipated 8-year operating life of the project (LOM). Total expected capital investment of US$92 million (including FEED of US$1 million) will yield an internal rate of return of 66% (after-tax) and annual EBITDA contribution of approximately US$77 million when producing at the 3,500 tpd throughput rate. The net present value (NPV) at 10% of the unlevered (no debt, all equity) cash flows is US$175 million. Based on the current mineral resource estimate (Inferred Resource) for the Project, a total of 965,000 AuEq ounces of gold, silver, copper and zinc would be produced at an all-in sustaining cost (AISC) US$1,127 per ounce.

Background

EnviroGold Global’s Hellyer Tailings Reprocessing Project began in August 2020 when Hellyer Gold Mines Pty Ltd (“HGM”) engaged the Company to assess the feasibility of recovering precious metals (gold, silver), clean energy, and battery metals (copper, lead, zinc) from the mine tailings located within HGM’s permitted tailings storage facility.

The Hellyer Tailings were produced from a volcanogenic massive sulfide (“VMS”) deposit with a complex mineralogical matrix that is resistant to conventional metal recovery techniques. Significant quantities of gold, silver and other critical and strategic metals were discharged into the tailings storage facility over the course of the primary and secondary processing activities. Extensive petrological investigation, including mineral liberation analysis (“MLA”) scans and laser ablation studies of the refractory tailings samples containing up to 55% of pyrite and arsenopyrite, indicated that the occluded gold is sub-microscopic and is locked within the crystal structure of the sulphide minerals. EnviroGold Global’s proprietary extraction process involves sulphide dissolution followed by agitated leaching of the remaining insoluble residue, resulting in significantly enhanced metal recoveries from difficult, complex feeds.

Other Information

The PEA and Mineral Resource Estimate have been prepared by independent Qualified Persons (QP) Jacques Houle, P. Eng., Rodrigo Carneiro, Engineer & MSc, and Dr. Rossen Halatchev, Engineer, MSc, PhD, in accordance with the requirements set forth in the CIM Definition Standards on Mineral Resources and Mineral Reserves (May 2014) and NI 43-101 standards and guidelines.

While capital and operational costs are preliminary and subject to variation, the Technical Report is a major milestone on the path to plant construction and metal production at the Hellyer site. It also discloses critical scientific and technical details of the resources contained in the Hellyer Tailings and the Company’s approach to enhance metal recoveries.

This PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized.
