Tactical Resources (RARE) has appointed Turnstone Metallurgical Services, led by Marcus Tomlinson, to lead the development of REE extraction and processing technologies.

Based in Vancouver, Canada, Marcus Tomlinson brings over thirty years of experience in metallurgical research, engineering, and operations support.

For over a decade, Marcus worked in the Corporate Technical Services groups at Goldcorp and Barrick Gold.

He founded Turnstone in April 2021 and has subsequently worked on the well-known Texas-based Round Top project in developing a fully integrated flowsheet to support the development of this rare earth, lithium orebody.

Upon Newmont’s acquisition of Goldcorp, Marcus served as Director, Modelling in the Newmont Global Projects team (2020 to 2021).

At Goldcorp (2012-2019), he served in the corporate technical services team as Director of Metallurgy & Research. During this time, he developed a patented process for concentrate enrichment and supported pre-flotation and pyrite leach projects at the Peñasquito Mine.

He was also involved in developing Goldcorp’s GeoMet strategy to improve the predictability of metallurgical performance and financial expectations from projects and operations.

Marcus has also worked with several major Engineering companies, including Worley Parsons Mining & Metals (2007 to 2008) in Australia, AMEC Americas Mining and Metals, Canada (2003 to 2007), Ausenco, Australia (2001 to 2003), AMEC Simons Mining Group, Canada, (1999-2001) and Fluor Daniel Mining & Minerals (1996 to 1999).

His career started as a Senior Metallurgist with Anglo American Research Lab (1992 to 1995) in South Africa.

He gained REE knowledge working with Lynas Corp on their REE concentrate cracking, solvent extraction, and purification projects while working with Ausenco, AMEC and Worley Parsons.

The company is looking to the future to identify solutions to advance its prospective properties towards development-stage and ultimately commercial-stage activities.

Company CEO Ranjeet Sundher notes, “With the addition of Marcus to the team, we have taken a major step towards achieving our goals.”

“We welcome him to our venture and look forward to working together to unlock the potential value of domestic REE during these troubled times,” added Sundher.

The company’s flagship Peak Project is a tailings offtake venture based upon active cut rock operations of the Sierra Blanca Quarry, LLC, in Hudspeth County, Texas located 68 miles southeast of El Paso.

Tactical Resources is a mineral exploration, and development company focused on rare earth elements based in Vancouver, British Columbia.

Tactical Resources (RARE) is down over 2 per cent, trading at C$0.92 at 12:09 pm EST.
