Rome Resources (AIM:RMR) announced it has identified a 2.6km tin-bearing quartz breccia at Scoullar Mountain, within the Mount Pleasant Caldera in New Brunswick, Canada, and will exercise its option to take full control of the surrounding 109km² land package.
The AIM-listed explorer, focused on critical minerals projects in the Democratic Republic of Congo and Canada, said the breccia sits a few kilometres east of the historic Mount Pleasant tin-tungsten deposit, one of the largest known tin-tungsten occurrences in North America.
Breccias at the new target contain stannite, a tin sulphide ore, alongside purple fluorite, the same mineral assemblage associated with indium at Mount Pleasant, which the company said indicates it is working within the same mineralising system rather than simply near it.
"We have identified a 2.6km tin-bearing quartz breccia at Scoullar Mountain, containing stannite alongside purple fluorite... so finding that same assemblage on our own ground tells us we are not simply working near a world-class deposit, we are working within the system that created it," said Paul Barrett, chief executive of Rome Resources.
Assays from the Scoullar Mountain breccia are pending.
Past trenching at Victoria Lake, along the greisenised roof zone of the Mount Douglas Granite, returned assayed samples of up to 0.58% tin and 0.17% tungsten, with over 370 metres of trenching completed and 54 samples sent for analysis awaiting results.
The company, meanwhile, plans 300 metres of trenching is planned to begin at Victoria Lake in early November.
At Square Lake, on the eastern margin of the same granite, outcrop sampling has returned bismuth of 0.8%, with further targets identified for follow-up.
The 2026 field campaign has covered 340 outcrop samples and 360 metres of trenching across the 109km² option area, with earlier sampling returning 17 parts per million indium, 0.8% bismuth and 1.5% copper, which the company said confirms the polymetallic critical mineral potential of the system.

Rome's partner has secured a further land package, taking the company's position within the Mount Pleasant Caldera sub-area to approximately 40km², immediately east and northeast of the Mount Pleasant licence.
The option exercise, previously announced, will be satisfied principally through the issuance of 225m new shares to Robert Murray, the optionor, restricted from trading beyond C$50,000 a year until the third anniversary of issuance.
Subject to results from the current programme, the company intends to plan a core drilling campaign in 2027, with the Mount Pleasant Caldera its principal focus in Canada alongside its flagship Bisie North project in the DRC.
