TNC Intercepts 6m @12.99 g/t Au and 10m Cu at Wallace North with Multiple High-Grade Zones

True North Copper Limited (ASX:TNC) (True North, TNC or the Company) is pleased to announce resource extension drilling and Induced Polarisation (IP) survey results at Wallace North, part of its Conclurry Project in Queensland, identified multiple open zones of high-grade copper and gold mineralisation. Wallace North has a current combined Indicated and Inferred resource of 1.39Mt @ 1.38% Cu and 0.90 g/t Au.

  • Drill results highlighted significant growth potential including:
    • Defining the down plunge continuity of a 100m wide, 250m deep high-grade copper gold shoot open at depth
    • Intersecting the top of an untested shoot, potentially 200m wide and open to depth.
  • Significant high-grade copper and gold mineralisation across drillhole results included:


− 10.0m (8.74m*) @ 2.22% Cu, 1.41g/t Au from 146.00m


− 6.0m (5.05m*) @ 0.43% Cu, 12.99g/t Au from 151.00m− 4.0m (3.35m*) @ 3.38% Cu, 1.81g/t Au from 88.00m


− 7.0m (5.55m*) @ 2.14% Cu, 1.13g/t Au from 110.00m


− 5.0m (3.82m*) @ 2.18% Cu, 7.31g/t Au from 182.00mInc. 2.0m (1.53m*) @ 2.89% Cu, 17.08g/t Au from 185.00m


− 3.0m (2.51m*) @ 3.57% Cu, 2.48g/t Au from 109.00m− 7.0m (5.90m*) @ 3.10% Cu, 1.32g/t Au from 214.00m

  • New IP geophysics and historic EM indicate substantial depth extent to the Wallace North system and highlight new targets with similar signatures to recent discoveries of gold-endowed iron-sulphide-copper-gold deposits in the Mt Isa Inlier.
  • Further development of Wallace North will include resource restatement, mining and metallurgical studies, downhole and ground-based geophysics and follow-up drillhole targeting (with completion expected Q1 2024).


True North Copper’s Managing Director, Marty Costello said:

“A successful resource expansion drilling and IP survey program at our fully permitted, 100%-owned, high-grade copper and gold Wallace North Project has identified multiple zones of high-grade copper and gold mineralisation outside the current resource shell, including Hole WNR0001, which included 10m (true width 8.74m) at 2.22% copper and 1.41g/t gold.

Additionally, the high-grade gold intercept of WNR0006 was a highlight with 6m (true width of 5.05m) of 0.43% copper and an impressive 12.99g/t gold.

The current Wallace North Resource is 1.39Mt has a copper grade of 1.39% and gold grade of 0.9g/t, but it does not have a Reserve. Thanks to this completed resource expansion drilling and IP surveying, along with our recently concluded advanced grade control drilling program, which included 150 drillholes and more than 9400m of drilling, we can now finalise an updated resource for Wallace North.

Wallace North is an important part of our Cloncurry Hub mining plans. This drilling program confirms there are several high- grade copper and gold zones within the Wallace North approved mining footprint, open at depth and warranting further exploration. More drilling will be undertaken across these zones and the anomalies we identified as part of recent IP surveys.

We are conducting revised metallurgical tests in conjunction with the upcoming technical tasks related to the development of the initial Wallace North Reserve Statement. This testing aims to validate effective extraction and processing methods. The prevalent copper mineralisation in the resource, as observed from our drilling, is chalcopyrite, which typically responds well to standard flotation. Given the gold is intertwined with the copper mineralisation, there is a strong possibility of extracting gold in a concentrated form during ore processing.”

Summary of TNC’s Drill Intersections to date

True North Copper has received assay results from eight (8) reverse circulation (RC) drillholes (WNR0001 to WNR0008) completed at its Wallace North Resource. These constitute both infill and extension holes to the 2023 resource1 (Figure 2 and Figure 3). Significant downhole intercepts are provided in Table 1 and illustrated in plan, long and cross-sections Figure 2, Figure 3, Appendix 1 .

Seismic Disruptions Could Cost Copper and Rhenium Industries Billions, USGS Study Shows

Astudy published by the US Geological Survey shows that earthquakes can have a "substantial" impact on mining, smelting and refining operations, creating lasting impacts for the global economy and supply chains.

Focusing on copper and rhenium, a silver-gray transition metal, the study aims to quantify the risks that earthquakes pose to supply — a variable that has not previously been systematically categorized.

Top 5 Copper Stocks on the TSX in 2024

Copper prices saw some gains during the first quarter of the year, but supply concerns and rising demand caused the copper price to surge in Q2 to a record high on the COMEX of US$5.20 per pound, or US$11,464 per metric ton, on May 20.

Although strong demand from the energy transition has been expected to impact supply chains for some time, lower treatment charges from Chinese refiners during the first quarter introduced added pressure into the market. The low charges caused cuts to output, ultimately bottlenecking the supply of refined copper to end users.

Top 5 Junior Copper Stocks on the TSXV in 2024

Many Canadian junior copper stocks are up significantly in 2024 thanks to a strong copper price.

The second quarter of 2024 saw carried-over momentum from March. Easing inflation and speculation of a manufacturing rebound fueled broad gains in commodity markets, helping to push COMEX copper prices to a record high of US$5.20 per pound, or US$11,464 per metric ton, on May 20.

Prices have found support over demand growth from energy sectors as wind and solar projects see greater uptake, particularly in China and India.

Chinese Copper Smelters to Trim Output in Response to Falling Margins

Two Chinese copper smelters have announced plans to reduce production next year due to diminishing profit margins caused by an ongoing shortage of ore concentrate, Bloomberg reported on Tuesday (July 16).

These decisions were revealed during a quarterly meeting of Chinese smelters held in Shanghai last week.

Daye Nonferrous Metals, a major smelter based in the country's Hubei province, plans to cut its smelting output by 20 percent in 2025. The company has already implemented smaller reductions, resulting in a decline in its total refined copper production capacity, which now stands at 930,000 metric tons on an annual basis.
