Sentinel Metals (ASX:SNM)
ASX newcomer Sentinel Metals (ASX:SNM) is banking on gold continuing its 2025 record streak with its advanced, 920,000oz Columbia gold project in Montana showing signs of supporting a strong run.
Investors share the company’s confidence, providing a stellar start to life on the ASX by firing SNM securities up as much as 62.5% above the 20c listing price to 32.5c before closing at 31c.
An IPO saw the company raise $10 million, giving it a value of $20m before ringing the bell.
Not only does Columbia have a JORC inferred resource of 920,000oz Au at 1.3g/t and 4.6g/t silver, there is a JORC-compliant exploration target of 22-27 million tonnes grading 1.1-1.4g/t Au for 800,000-1.2Moz of contained gold.
And there is upside with the project returning drill results of up to 3.1m at 106g/t gold from 33.5m along with 12.2m at 11.6g/t from 1.5m and 132.6m at 2.01g/t from 15.2m.
More than 45,000m of historical drilling and trenching have defined a low-sulphidation epithermal gold-silver system which remains open in all directions with high-grade potential at depth.
A significant body of historical technical work has been undertaken, confirming it is a low sulphide orebody amenable to environmentally friendly thiosulphate-glycine processing.
Testwork achieved 96% total gold recoveries from gravity and flotation, with combined flowsheet tests achieving up to 96% recovery for gold and 77% for silver.
Backing up SNM’s confidence is that Columbia is in a Tier-1 US jurisdiction with support from federal and state governments for new mining ventures.
Adding strength is the executive team led by an experienced team of mine-builders, including ex-Red 5 boss Mark Williams as chair and former FMG and Rio Tinto executive Matthew Herbert as managing director and CEO.
RareX (ASX:REE)
A non-binding MOU between RareX (ASX:REE) and US Strategic Metals is aimed at further developing critical mineral supply chains between Australia and the US.
USSM is focused on becoming the first major near-term domestic producer of critical minerals in the US with its fully permitted site in Missouri.
REE brings to the partnership Australia’s largest undeveloped rare earth deposit, the Cummins Range project in WA, at which metallurgical testing is being completed and a Mining Licence is expected in early 2026.
Cummins Range is a multi-critical-mineral deposit containing rare earths, gallium, scandium and phosphate with access to the Port of Wyndham.
The partners will establish a working group to progress feasibility and technical assessments at the USSM site in Missouri and evaluate downstream integration.
Mount Ridley Mines (ASX:MRD)
As Western demand for critical minerals increases, Mount Ridley Mines (ASX:MRD) has revealed a significant maiden resource of gallium at its namesake project in southern WA.
The maiden inferred resource of 838.7Mt grading 29.3ppm for 24,584t of gallium extending from just 4m to 61m vertically represents a valuable, secondary mineral at the Mt Ridley project, which was originally known for its rare earths mineralisation.
Gallium is hosted in the same clay and saprolitic horizons as the REEs and the potential was firmed up during MRD’s assessment of the broader critical minerals potential of the project, including scandium.
MRD is now investigating potential innovative metallurgical solutions targeting a mixed REE carbonate product with gallium and other critical elements as secondary recoveries.
Pivotal Metals (ASX:PVT)
An injection of funds will enable Pivotal Metals (ASX:PVT) to accelerate exploration, including drilling, at the Belleterre project in Quebec, Canada.
A $4.25m placement was anchored by Australian resources investor Matthew Latimore, who joins the PVT register as a substantial holder.
This was supplemented by $1.1m through Canada’s flow-through share scheme, adding non-dilutive capital.
Drilling at Belleterre is scheduled to start in December at the Alotta conductor which is directly beneath high-grade hits such as 24.2m at 2.3% copper, 1.2% nickel and 1.9 g/t 3PGE from 53.1m, as well as 15.7m at 3.1% Cu, 1.6% Ni and 2.9 g/t 3PGE from 55.3m.
Lakes Blue Energy (ASX:LKO)
After what it describes as a transformational quarter, Lakes Blue Energy (ASX:LKO) has risen almost 32.5% to $1.55.
During the September quarter the company was reinstated to the ASX, carried out a $5.8m capital raise with institutional and strategic investor participation and completed the Wombat-5 well at the wholly owned Wombat Gas Field in Victoria’s Gippsland Basin.
Wombat-5 reached a total depth of 3052m, drilling 1.5km of horizontal production hole through the gas-saturated Strzelecki Formation, intersecting multiple high-quality sandstone reservoirs.
Excellent gas shows were recorded throughout drilling, including concentrations up to 67.5% C1-C5 in the best-developed sand packages correlating with Wombat-5.
Production testing is scheduled to commence in mid-November.
