# Hellyer Metals

## 🏢 Company Overview

**Hellyer Metals** is a privately held Australian mining company, advancing a tailings reprocessing operation at the Hellyer Mine in northwest Tasmania. The company emphasises **environmental rehabilitation**, leveraging hydro‑powered operations and ESG practices to minimise footprint and boost sustainability in mining practices.

## 🌍 Hellyer Mine & Tailing Project

* **Historic polymetallic source**: The original underground mine, active from 1989 to 2000, produced lead, zinc, copper, gold, and silver from massive sulfide orebodies on the Mount Read Volcanic Belt.
* **Tailings restart**: In 2017 Hellyer Metals (via NQ Minerals) acquired \~9–11 Mt of tailings from the tailings storage facility, launching dredging in 2018. The project has a projected 10-year mine life.
* **Processing flow**: Slurry dredged and pumped to a 1.6 Mtpa flotation plant producing lead, zinc, gold/silver credits, and from 2024, a pyrite concentrate for metals extraction

## 🔬 Resources & Recovery

* **Tailings composition**: Approximately 54% pyrite, 20% sphalerite, 8% galena, 1–2% chalcopyrite/arsenopyrite; 2020 JORC resources: 6.37 Mt of measured & indicated + 1.21 Mt inferred, averaging 2.60 g/t Au, 94 g/t Ag, 2.33% Zn, 3.01% Pb.
* **Recovery rates**: Pilot tests achieved gold recovery of \~83.5% and silver \~94.6%, with copper \~91% and zinc \~82% using proprietary hydrometallurgy developed with EnviroGold Global.

***

## 🛠 Expansion & Underground Scope

* **Fossey & Fossey East**: Fully permitted upstream underground deposits with substantial upside—they remain open at depth, and dewatering began in Q4 2023.
* **Exploration drilling**: Using advanced geological modelling, four high-priority targets are being drilled to expand reserves and potentially extend mine life.

***

## 🤝 Strategic Partnerships

* **EnviroGold Global**: A binding agreement in 2022 to apply hydrometallurgical technology to Hellyer tailings. The partnership is a key catalyst for enhanced recoveries and circular-economy mining.
* **Tech validation**: Perth pilot plant in mid‑2023 confirmed strong recoveries and scalability of the process.
