Siren Gold (ASX:SNG)

+95% Gold and Antimony Recoveries at Auld Creek

Siren Gold Limited (ASX: SNG) (Siren or the Company) is pleased to provide an update on its Auld Creek Project in Reefton.


Highlights

  • Three metallurgical samples from Auld Creek were tested for gold and antimony recoveries at ALS in Perth.
  • All three samples gave excellent gold flotation recoveries ranging from 95-98%.
  • Antimony recoveries are modest (around 64-90%) using copper sulphate as an activator.
  • Changing from copper sulphate to lead nitrate as an activator boosted antimony recovery from 71% to 97%.
  • The rougher concentrate grade for the lead nitrate test was 44.8g/t Au and 13.2% Sb. Cleaning tests are expected to enhance these grades further.
  • Additional optimisation work using lead nitrate as an activator is expected to commence in Q4 of CY2024.
Siren Managing Director and CEO, Victor Rajasooriar commented:

” These are excellent results as we progress our Reefton gold and antimony projects into the future. The commodity pricing outlooks for both metals are excellent and the introduction of antimony as a critical mineral brings additional potential benefits to New Zealand. We are now in the final stages of completing our Auld Creek mineral resource calculations following the drilling program earlier this year and expect to have that completed in the coming weeks. Concurrently, additional metallurgical testwork will be carried out to optimise the recoveries of antimony at Auld Creek.”

Background

Three metallurgical samples were collected from Auld Creek diamond core within the Fraternal Shoot to test for both gold and antimony recoveries into a flotation concentrate. The samples were delivered to ALS Perth in May 2024 for a range of metallurgical tests under the supervision of metallurgist Graham Brock (Leo Consulting Ltd).

AC001 was collected from the top of the shoot that has little or no antimony. AC002 was collected from the middle of the shoot with high grade gold and antimony and AC003 was collected to represent the average resource gold and antimony grades (Table 1 and Figure 1).

AC001 Flotation Tests

Three tests were conducted on the low-grade antimony sample AC001. Test 1 was a standard kinetic rougher test giving a 95.8% recovery of the gold into the rougher concentrate at a grade of 51.2 g/t Au. Antimony recovery was also high, but the head grade was low at 0.05%.

Tests 2 and 3 were kinetic cleaner tests; Test 2 had no regrind and Test 3 included a regrind step. Test 2 produced a high-grade concentrate assaying 120.6g/t Au and Test 3 produced a grade of 136.6g/t Au. Gold recoveries were 91.9% in Test 2 and 87.7% in Test 3.

In summary, if this material was fed to a flotation concentrator 6% by weight would go to a 51g/t Au concentrate at 95.8% gold recovery. To reduce transport costs a cleaner circuit could be introduced such that for a small loss of recovery only 2.6% by weight at a grade of 120g/t Au could be produced. Testing showed little benefit in the regrind step.

North Stawell Minerals

High-grade Gold Intercept Confirmed at Darlington

North Stawell Minerals (ASX:NSM) is pleased to announce an update on the results of its recent diamond drill program. The North Stawell Project includes a 504 km2 contiguous package of ground that incorporates the gold-prospective corridor immediately north of Stawell Gold Mines’ operation at Stawell. A thin blanket of unmineralised sediments preserves potential for large, near-surface repeats of the multimillion-ounce ore deposit at Stawell. The current focus is on two priority targets, Wildwood and Darlington, which both have potential to be repeats of the multi-million-ounce mineralisation at Stawell.

Gold Price Hits New Record, Touching US$3,500 for First Time

The gold price reached yet another record high on Tuesday (April 22), hitting US$3,500 per ounce.

In trading on Monday (April 21), the precious metal surged past the US$3,400 mark; it then briefly touched US$3,500 early on Tuesday morning before settling in the US$3,425 to US$3,450 range.

Gold has been on the rise all year, with the latest boost coming after US Federal Reserve Chair Jerome Powell spoke at the Economic Club of Chicago on April 16. In his remarks, he said he expects US President Donald Trump's tariff policy to negatively impact American economic growth and further fuel inflation in the country.

Gold's momentum was boosted in the following days as Trump made his own statements suggesting he is seeking ways to remove Powell as the head of the US central bank. However, the Fed operates at arm's length, and it would require an act of Congress to remove Powell from his post. Powell's term is set to expire in May 2026.

Black Cat Pours First Gold at Lakewood Processing Facility

Black Cat Syndicate (ASX:BC8,OTC Pink:BLCAF) has successfully poured first gold at its recently purchased Lakewood processing facility, marking a key milestone for the company.

The pour took place on April 16, with 757 ounces of gold produced at the site.

The Lakewood facility, acquired by Black Cat on March 31, is located 6 kilometres southeast of Kalgoorlie, Western Australia, and within 40 kilometres of Black Cat’s fully owned Kal East gold operation.

Processing began on April 1, immediately after Black Cat took possession of Lakewood. Since then, the company has hauled 60,000 tonnes of ore from Kal East's Myhree open pit to the processing facility.

“The commencement of processing through Lakewood has started well with throughputs, grade and recoveries all above expectation,” said Black Cat Managing Director Gareth Solly.

WIN Metals Updates Butchers Creek Gold Resource, Plans to Advance Development

WIN Metals (ASX:WIN)will now advance toward developmental studies for its Butchers Creek gold project.

The company released an updated mineral resource estimate for the asset on April 16, saying it now stands at 5.23 million tonnes at 1.91 grams per tonne (g/t) gold for 321,000 ounces of gold.

The project's indicated resource has increased by 86 percent, coming in at 3.58 million tonnes at 2.24 g/t gold for 258,000 ounces of gold. The inferred category holds 1.66 million tonnes at 1.18 g/t gold for 63,000 ounces of gold.

Butchers Creek is located in the East Kimberley region of Western Australia and historically produced at least 52,000 ounces of gold. According to WIN, open-pit mining took place at the site between 1995 and 1997.

WIN acquired Butchers Creek from Meteoric Resources (ASX:MEI,OTC Pink:METOF) in late 2024. According to the company, it hosts numerous high-order drill targets from over 60 known gold occurrences.
