DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.
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 ...

The announcement comes after the company said earlier this year that results of Phase 1 of the Hellyer Tailings Reprocessing Project, at the Hellyer Gold Mine, Tasmania, Australia, are expected in early 2023 and will be a key milestone to deploying a full-scale pilot program as a precursor to plant engineering and construction there.
Generally, metals are extracted from ores collected from hard rock mines. Recent advancement in mineral extraction technologies and declining ore grades in primary deposits have led to the idea of reprocessing of mine tailings as the potential secondary source of some of the critical minerals [15], [16], [17], [14].
With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a cost-effective approach compared to processing material.
Tailings are the mineral waste remaining after ore processing to extract mineral concentrates and are typically stored within an engineered containment structure known as a tailing storage facility or TSF. Tailings differ from overburden: the waste rock or material that overlies an ore or mineral body and is displaced unprocessed and stockpiled ...
Mining of arsenopyrite-bearing gold ores in Nova Scotia in the late 1800s and early 1900s has left a legacy of weathered, As-rich tailings deposits in more than 60 gold districts across the province.
Subsequently, EnviroGold Global will reprocess additional tailings from legacy mining operations located on the Hellyer Mine Site. EnviroGold Global is entitled to 50% of the pre-tax cashflows resulting from the tailings reprocessing operations up to US$24 million/yr; thereafter, EnviroGold Global is entitled to 65% of the pre-tax cashflows.

Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it's important to reshape tailings management and accelerate the positive change.
