With more than 600,000 average monthly users on the HotCopper forums, individual discussions there can move markets, which is why staying ahead of the platform's hottest trends matters for traders. In this daily HotCopper Trends column, the top Australian stocks of each trading day are broken down.

Kaoko Metals (ASX: KAO)

Kaoko Metals took off after visual copper mineralisation was logged over broad down-hole zones in the first two diamond drill holes completed at the Otniel prospect, part of its Chalkos copper-silver project in Namibia. Namibia has attracted growing exploration interest in recent years, with the country hosting established copper-producing operations such as the Otjihase and Matchless mines historically, and explorers drawn to its underexplored Proterozoic belts. Gains on visual mineralisation announcements like this are common among early-stage explorers, though the market reaction typically awaits laboratory assays for confirmation of grade and width.

"While it is still early in the program and we are waiting for results of the initial assays, we are pleased to have observed broad zones of copper mineralisation in the first two holes at Otniel," Managing Director Gerard O'Donovan said.

"This is a highly encouraging start to the first ever drilling of the 800 sq. km Chalkos project and we are excited to continue drilling at both the Otniel and Donkey Hill prospects."

KAO closed up 142% at $1.78. The pending assay results from the initial holes are the next data point investors will be watching.

Australian Gold and Copper (ASX: AGC)

Australian Gold and Copper was higher again after confirming a significant high-grade precious and base metal discovery in the newly identified western zone at the Evergreen prospect within its South Cobar project in New South Wales. The Cobar region is one of Australia's established mining districts, home to long-running operations such as Endeavor and Peak mines, and has seen renewed exploration activity as companies pursue undercover mineral systems in the prolific Lachlan Fold Belt's western margin.

New results extended the recently reported western zone gold mineralisation approximately 150 metres to the south, confirming high-grade mineralisation in both oxide and sulphide domains.

"We interpret this new western zone to have now been intersected over approximately 150 metres of strike, from recently reported oxide gold-silver mineralisation in 26DDBR013 to high-grade sulphide mineralisation in 26DDBR017," Managing Director Glen Diemar said.

"This is a major step forward in understanding the scale and tenor of the Evergreen system."

AGC jumped 18.5% to 16.0 cents.

Lion Rock Minerals (ASX: LRM)

Lion Rock Minerals drew attention after a targeted revaluation of retained Minta Est auger drill material delivered multiple high-grade, multi-metre rare earth intervals from surface that remain open at depth. Rare earths have become a focal point for explorers globally as governments including Australia's have designated them critical minerals central to energy transition technologies such as electric vehicles and wind turbines, driving increased exploration and government support programs for the sector.

CEO Theuns de Bruyn said the results provide the first direct full-suite chemical assay of these earlier drill intervals, while a separately completed 761-hole alluvial drill campaign and its 3,666 samples are entering the assay sequence.

"Following the recent board and technical team appointments, the company has undertaken a comprehensive review of the exploration and targeting strategies across the Minta Project portfolio," he said.

"The focus of previous exploration was predominantly towards rutile within surficial mineral sands. Taking a broader approach, the Company conducted ICP-OES multi element analysis across stored samples of auger drilling."

LRM rose 11.1% to 2.0 cents.

Broader Market: S&P/ASX 200

The S&P/ASX 200 was lower, dropping 114.20 points, or 1.26%, to 8,952.50. The index's worst performers were Iperionx and Kingsgate Consolidated, down 7.74% and 7.44% respectively. The index has lost 1.92% over the last five days and sits 3.70% below its 52-week high.

GDP Data

Elsewhere, Australian gross domestic product (GDP) rose 0.4 per cent in the June quarter 2026 and 2.1 per cent compared with the June quarter 2025 (seasonally adjusted, chain volume measure), according to figures released by the Australian Bureau of Statistics (ABS).

"Economic growth remained subdued in the June quarter as households continued to behave cautiously," said Grace Kim, ABS head of National Accounts. "While increased spending and business investment occurred in pockets of the economy, imports supported much of the growth, moderating its contribution to overall GDP growth."
