Mineral companies within the non-energy minerals, energy minerals, process industry and producer manufacturing sectors were considered.

1. ?OD6 Metals (ASX:OD6)

Weekly gain: 103.7 percent
Market cap: AU$18.42 million
Share price: AU$0.110

OD6 Metals is focused on exploring and developing critical minerals projects in Australia and the US, with headquarters in Subiaco.

The company’s Australian portfolio includes the advanced-stage Splinter Rock clay-hosted rare earths project in Western Australia’s Esperance–Goldfields region. Splinter Rock holds a JORC mineral resource estimate of 682 million tonnes grading 1,338 parts per million total rare earth oxides (TREO). OD6 is currently advancing metallurgical testwork and engaging with potential offtake partners, with plans to begin production in five years.

OD6 also owns the Gulf Creek copper-zinc project in New South Wales, a high-grade VMS style deposit that was mined for copper between 1896 and 1912.

On Wednesday (March 4), OD6 announced it entered an exclusive option agreement to wholly acquire the Quinn fluorspar project, comprising a district scale cluster of fluorspar deposits and prospects in Nevada, US. The release ended a trading halt that began Monday.

“Fluorspar is a designated U.S. Critical Mineral widely used in industrial, pharmaceutical and technology applications,” Managing Director Brett Hazelden commented. “The United States is currently 100 percent import dependent and this presents a compelling strategic opportunity as the US Government prioritises greater domestic production of critical minerals.”

The release also noted OD6 received commitments for a two-tranche AU$3.4 million private placement.

After closing at AU$0.054 last week, shares of the company jumped to AU$0.091 Wednesday following the news and climbed to AU$0.110 on Thursday.

A key development project for the company is the Kiwi liquids-rich gas field in the Cooper Basin. Previous testing at the Kiwi 1 well demonstrated production rates of 4.1 million cubic feet of gas per day and 988 barrels of condensate per day.

Last week, Kiwi was awarded an AU$3.5 million grant from the South Australian Government’s Gas Initiative program. The company said the grant will support the construction of a pipeline connecting the Kiwi gas field to the existing Cooper Basin infrastructure.

The company closed last week with the release of its January operations update , highlighting a daily oil production average of 237 barrels of oil per day, with a total monthly production of 7,342 barrels.

The company halted trading last Friday, February 27, pending an important announcement.

On Tuesday (March 3), Lindian announced it executed a binding term sheet to acquire an existing SARECO mixed rare earths carbonate (MREC) processing facility in Kazakhstan. To do so, the company entered a 51/49 joint venture with Kazakh company RA Group, and the pair jointly acquired 100 percent of the facility for a combined US$15 million.

The facility was originally established by a partnership between state company Kazatomprom and Japanese company Sumitomo (OTCPK:SSUMF,TSE:8053) .

Lindian said the acquisition transforms its plan from concentrate sales to high-value MREC production using monazite concentrate from Kangankunde.
