Rome Resources (AIM:RMR), the DRC focused tin explorer, said outcrop sampling at its optioned claims in southwest New Brunswick, Canada has returned assays of up to 0.6% tin, 0.2% tungsten, 0.8% bismuth, 17ppm indium and 1.5% copper.
The results come from a field campaign targeting the greisenised roof of the Mount Douglas Granite, a system that sits close to the Mount Pleasant tin-tungsten deposit and is considered prospective for critical minerals including indium.
Rome Resources entered option agreements over the New Brunswick claims on 10 March, and began reconnaissance mapping and sampling in May.
At the Victoria Lake project, tin and tungsten mineralisation has been traced along a 300 metre wide zone, with a historical drillhole showing tin extending to depth; trenching there begins in early September.
At Square Lake, outcrop sampling has returned a bismuth grade of 0.8%.
"These initial results at New Brunswick are highly encouraging, pointing to extensive mineralisation for tin and tungsten, along with the potential for higher value critical metals such as indium and bismuth", said chief executive Paul Barrett.
Trenching and sampling will continue through September and October, with the company aiming for a core drilling campaign in 2027 subject to exercising its option on the claims.
News Intelligence what this means for the company
Rome Resources has returned early-stage assay results from outcrop sampling at its optioned New Brunswick claims in Canada, with tin grades to 0.6%, tungsten to 0.2%, and bismuth to 0.8%, alongside trenching scheduled for September 2027 and a possible drill campaign in 2027. The company entered these option agreements in March 2026 and began field work in May; the results are preliminary reconnaissance data from a junior explorer with no production revenue, so the significance lies in whether the grades and geometry justify the cost and time of deeper testing rather than in any immediate commercial impact.
Rome Resources is diversifying its exploration footprint beyond its DRC tin focus into Canada, but remains an early-stage junior with no revenue and limited cash (£1.4m as of June 2026). These New Brunswick results do not alter the core investment case—the company's value still hinges on whether its DRC assets (Kalayi, Bisie North) advance to resource definition and whether it can fund exploration through option agreements and small-scale mining rather than equity dilution.
