Australian small-cap names Mount Ridley Mines (ASX: MRD), Bass Oil (ASX: BAS) and Broken Hill Gold (ASX: BH6) were among the most-discussed stocks on the HotCopper forums on Thursday, with each company drawing trader attention after releasing fresh operational or exploration updates.

HotCopper, which counts more than 600,000 average monthly users across its forums and describes itself as Australia's largest stock forum, is a platform where individual discussions can move markets. In its daily HotCopper Trends column, presented by Colin Sandell-Hay, the platform breaks down the top Australian stocks through each trading day.

Mount Ridley Mines (ASX: MRD)

Mount Ridley Mines climbed after reporting results from the first third-party test of its wholly owned and patent-pending Selectro process. Independent testwork of this kind is a common route for companies seeking to demonstrate that a proprietary processing method performs on material beyond their own deposits, and the update landed on a day when the benchmark index finished essentially flat.

Managing Director and CEOister Caird said the results represent an important milestone in demonstrating the application of Selectro beyond the company's existing Grass Patch mineral resources and into the broader metal processing industry.

"This is a remarkable result for Selectro. Bauxite is a very different material to our Grass Patch feed, and achieving these recoveries on our first test demonstrates the potential for Selectro to be applied well beyond MRD's existing mineral resources," Mr Caird said.

For context, bauxite is the principal ore of aluminium, so a strong result on that feed material points to potential applications well outside the company's current resource base.

MRD was up 13.9% to 4.1 cents.

Bass Oil (ASX: BAS)

Bass Oil was a popular topic on HotCopper following positive news in its latest operations update. Total sales revenue for September was $1,686,790 net to Bass, up 136%. Figures reported "net to Bass" reflect the company's own share of sales from the assets rather than gross field revenue, a standard convention in oil and gas reporting.

"September marked a milestone when Bass' growth projects started delivering for the company," Managing Director Tino Guglielmo said.

"Oil production and sales have increased against a backdrop of persistently high oil prices boosting free cashflow. With the Bunian 6 oil well online our focus turns to delivering first gas sales from the Vanessa field.

"I am very proud of the efforts of our Indonesian and Australian teams for continuing to deliver our growth projects safely and professionally," Mr Guglielmo added.

With Bunian 6 online, first gas sales from the Vanessa field stand as the company's stated next milestone and the item to watch in forthcoming updates.

BAS jumped 8.47% to 6.4 cents.

Broken Hill Gold (ASX: BH6)

Broken Hill Gold jumped after revealing it had identified a number of near-mine targets at the White Dam gold-copper project in South Australia. Near-mine exploration draws particular attention because targets close to existing workings and infrastructure are typically faster and cheaper to test than greenfield ground.

Induced polarisation (IP) and magnetic geophysics completed over the last five weeks have provided a promising new dataset to guide exploration on the potential expansion of the Icebreaker sulphide gold-copper mineralisation. IP surveying measures how the ground holds electrical charge and is widely used in mineral exploration to help detect sulphide mineralisation below the surface.

"This is an excellent result, delivered in a very short turnaround time, and the geophysics crews have performed exceptionally. We now have coincident IP and magnetic anomalies over a large area, in a zone we already know is well mineralised – that is an extremely compelling set of drill targets," Managing Director Matthew Boyes said.

"The strength and consistency of the IP anomaly makes it an outstanding target in its own right."

The company has framed the anomalies as drill targets, so follow-up drilling is the next tangible step for the project.

BH6 was up 8.33% to 13.0 cents.

Broader market

The S&P/ASX 200 was down just 4.60 points at 8,723.30 on Thursday. The bottom-performing stocks were Ingenue Communities and Silex Systems, which fell 11.90% and 11.05% respectively. Over the last five trading days the index has gained 0.72% but remains virtually unchanged year to date — a backdrop that made the sharp single-stock moves in the three forum favourites all the more noticeable.

September jobs data

Meanwhile, the seasonally adjusted unemployment rate was 4.7% in September, according to the latest data from the Australian Bureau of Statistics (ABS). Monthly labour figures are among the most closely watched reads on domestic economic conditions, and this release pointed to a softening labour market.

"This month there were 39,000 less employed people and 9,000 more unemployed people," said Sean Crick, the ABS's head of labour statistics.

"As a result, the employment to population ratio fell 0.3 percentage points to 63.6%, and the participation rate fell 0.2 percentage points to 66.8%.

"This September a higher proportion of people remained unemployed compared to recent years.

"This follows from last month when a higher proportion of people who were previously not in the labour force moved to being unemployed."
