As the world shifts its focus on utilizing eco-friendly materials and sources of energy, MetalsGrove focuses on green metal exploration and development to meet the growing demand from the battery storage and renewable energy markets in the transition to a decarbonized world. There is an ever-increasing demand for environmentally and commercially sustainable development and a supply of materials that feed into these industries that subsequently flow onto all facets of our society both at a domestic and industry level.
MetalsGrove has a strong portfolio of lithium, tin, tantalum, rare earth, manganese, copper-gold, and base metal exploration projects that have the potential to augment the global demand for metals required to achieve a low emission future. The projects are all based in the Tier One jurisdiction of Australia and located in Western Australia and the Northern Territory.
Led by a proven board, management and advisory team driven by ESG principles, the launch of MetalsGrove coincides with an exciting shift in the demand profile for lithium, rare earth elements (REE), manganese, and copper.
One of MetalsGrove’s priority focuses will be on The Bruce Project which is highly prospective for Rare Earth Elements (REE).
Some quick facts and further details on this exciting opportunity are discussed below.
Bruce-Rare Earth (REE) Project
The Bruce Project is located within the Central Desert Region of the Northern Territory and covers an area of approximately 17,722 ha.
The nearest historical mine is the inactive Harts Range garnet mine (approximately 80 km to the west-southwest) while the Molyhil tungsten-molybdenum project (Thor Mining PLC) is approximately 10 km to the northeast.

More recently, the Project has been considered by the Company to be attractive due to the pegmatitic outcrops hosting several siliceous and micaceous occurrences on the potential that they may be LCT and/or rare earth (REE) bearing. There are many relic mica mines in the region. These pegmatites are typical of those associated with granitic domes within Archaean terranes of WA and often contain red, orange, and brown almandine garnet. Smaller garnet crystals are indicative of proximal alteration which may influence mineralization. Large crystalline mica books are present as crystals in the feldspathic, quartz host rock of the pegmatites.
The central region of the tenement requires detailed geological and structural mapping to understand what relationships, if any, exist between the known Au-Cu mineralization and the potential LCT and/or rare earth (REE) mineralization.
The Bruce Prospect falls within one of the two geochemical groups identified by Hoatson (2001) that Arunta intrusions fall into (i.e., the relatively sulphur poor (<300 ppm 5) group amphibolites of the eastern Arunta (including at the Bruce Prospect)) purported to both have the potential for hydrothermal polymetallic mineralization spatially associated with the intrusions.
Historical Pegmatite Workings and Potential Gold-Copper Corridor Location Plan
The Bruce Project tenement covers Lower Proterozoic rocks along, and flanking, the Delny-Mt Sainthill Fault Zone and Entire Point Shear Zone, which has developed within a wide west-northwest trending tectonic zone along the northern boundary. Most of the project tenement is overlayed by Quaternary alluvium and soils. The project tenement is host to the historical Plenty River Mica Mining Area. Near the centre of the tenement lies the historical Bruce Gold–Copper occurrence. The prospect is associated with quartz veins, where east-trending quartz veins contain Cu and also locally contain Au (up to 53 ppm Au; Wygralak and Mernagh 2005).
Throughout the Bruce project are many outcropping quartz veins showing a variety of gossanous, vuggy and oxidised characteristics. Many of the veins are brecciated and contain clasts of remnant primary sulphides or of remnant sulfidic sediments.
Several historical pegmatite workings are located within the project area with geological mapping reportedly suggesting potential for pegmatite-hosted rare earth element mineralisation in the project tenement. In the southwest of the project, northeast trending pegmatites hosting historical mica workings are present. No focussed rare-element granitic lithium-caesium-tantalum (LCT) pegmatite exploration has occurred at the project previously.
