Nifty Heap Leach Mineral Resource Estimate

Cyprium Metals Limited (ASX: CYM) (Cyprium) is pleased to announce the 2024 Mineral Resource Estimate (MRE) for the existing above-surface material stacked on the heap leach pads at the Nifty Copper Mine (Nifty) in Western Australia.


Highlights include:

 
  • Indicated and Inferred Mineral Resource Estimate of 12.7 million tonnes grading 0.43% Cu for contained copper of 54,050 tonnes
  • 2021 sonic drill campaign incorporated into drill database
  • Potential for further upside as drill data does not extend to the bottom of the material on the heap leach pads
 

“This is back-to-basics execution,” said Cyprium Executive Chair, Matt Fifield. “Restarting the cathode plant is the next logical step for Cyprium’s new management team and the first phase of Nifty’s redevelopment. To move towards operations, we need comprehensive and up to date resource information. Our team produced this MRE by going back to first principles, organising and incorporating all prior existing data, and including new analysis from the 2021 sonic drill program. The result is the first updated MRE since 2015 for the unrecovered copper on Nifty’s heap leach pads. It’s a strong foundation on which we can build our forward plans.”

The 2024 Heap Leach MRE defines an indicated and inferred copper resource containing approx. 54,000 tonnes of copper that is supported to JORC standards through drilling information – see Table 1 below. A review of historic production data indicates that there is substantial potential resource upside from unsampled stockpiled material. This unsampled material is not able to be supported through drilling information as all drill holes were halted short of the pads to maintain the integrity of the pad and liner.

The 2024 MRE incorporates new data from a 2021 sonic drill program which was run in support of previous feasibility studies. Analysis of samples obtained from the sonic program have supported important metallurgical inputs on the drilled resource.

The 2024 Heap Leach MRE is the first update of an MRE on this material since 2015. The mineral resource in Table 1 represents the portion of the stockpile that was estimated from drill data in accordance with the JORC (2012) code.

Nifty Copper Project Poised to Unlock Value for Cyprium Metals, Report Says

Description

The latest MST Access analyst report values Cyprium Metals (ASX:CYM) at AU$0.10 per share, significantly above its current trading price of AU$0.027. The valuation is underpinned by the company’s dual-track approach to restarting the Nifty copper project, a standout asset with a 20-year mine life and the potential to become one of Australia’s largest open-pit copper producers.

By leveraging existing infrastructure and its low capital intensity, Cyprium is positioned to deliver exceptional returns, according to the report. With plans to secure a strategic partner in 2025 and a fast-tracked production timeline for its Cathode project, Cyprium represents an undervalued opportunity in the ASX copper space.

Cyprium Metals Ltd  Nifty East Extensional Infill Drilling Results

Cyprium Metals Ltd Nifty East Extensional Infill Drilling Results

Perth, Australia (ABN Newswire) - Cyprium Metals Limited (ASX:CYM) is pleased to announce that assay results have been received from the Nifty East infill extensional drilling. The program comprised 21 RC holes for 5,725m targeting areas from the previous program which identified encouraging widths of oxide/transitional mineralisation extending east and sulphide mineralisation extending east at depth beneath the former Nifty open pit (Figure 1*).

HIGHLIGHTS

- All results received from Nifty East Extensional Infill drilling program, targeting the oxide/transitional mineralisation and sulphide mineralisation at depth beneath the open pit

- Results demonstrate potential to define additional shallow mineralisation for the planned heap leach restart and grow the existing +0.9 Mt contained copper Mineral Resource

- Significant widths of copper mineralisation intersected are shown below

Executive Director Barry Cahill commented:

"The first phase of drilling at Nifty East has firmed up our understanding of the copper mineralisation extending from the current Nifty open pit and clearly demonstrates excellent potential to grow the existing resource further east. The results will be added to the resource model. These East drilling results along with the previously released West drilling clearly demonstrate the potential to expand the mineral resource as further phases of drilling proceed.

Discussion of results

Section 102,800E

Hole 21NRSP021 confirmed oxide mineralisation that was previously intercepted in holes 21NRSP006 and 21NRSP011 (Figure 3* 18m at 0.45% Cu, including 1m at 2.35% Cu). Hole 21NRSP021 also extended sulphide mineralisation at depth within the carbonate-shale host rocks (4m at 0.36% Cu, 3m at 0.47% Cu and 17m at 0.52% Cu, including 2m at 1.14% Cu and 6m at 0.16% Cu).

Section 102,840E

Hole 21NRSP030 confirms oxide mineralisation close to surface that was previously intersected in hole 21NRSP001 and historical drillhole NCP0317 (Figure 4* 3m at 0.15% Cu, 3m at 0.14% Cu and 5m at 0.26% Cu). Three deeper holes intercepted sulphide mineralisation extensions at depth where there is no historical drilling.

Hole 21NRSP0022 intercepted 3m at 0.19% Cu, 11m at 0.66% Cu including 2m at 1.57% Cu and 3m at 0.31%, and 5m at 0.51% Cu including 1m at 1.40% Cu. Hole 21NRSP0031 intercepts include 6m at 0.33% Cu and 7m at 1.14% Cu including 4m at 1.76% Cu. 21NRSP0032 intersected 3m at 0.21% Cu, 3m at 0.29% Cu and 4m at 0.20% Cu.

Section 102,880E

Figure 5* illustrates infill transitional and sulphide mineralisation which was intercepted in hole 21NRSP039 (3m at 0.69% Cu including 1m at 1.21% Cu, 3m at 0.44%, 4m at 0.30% Cu, 5m at 0.18% and 3m at 1.18% Cu including 2m at 1.38% Cu), and Hole 21NRSP023, which intercepts upper sulphide mineralisation (12m at 0.74% Cu including 2m at 1.20% Cu and including 1m at 1.50% Cu and including 1m at 1.26% Cu).

Section 102,920E

The drilling has identified further extensionsto the oxide mineralisation east of the Nifty pit. The mineralisation is mostly in proximity to the northern limb of the Nifty Syncline. It has also been confirmed to extend further south, interpreted as an extension of the sub-parallel zone of supergene copper mineralisation, which was identified in the first phase of drilling by Cyprium Metals in 2021.

Hole 21NRSP0033 (4m at 0.14% Cu, 3m at 0.16% Cu, 6m at 0.22% Cu, 14m at 0.27% Cu, 5m at 0.17% Cu and 3m at 0.26% Cu) and Hole 21NRSP034 (3m at 0.13% Cu, 4m at 0.16% Cu, 3m at 0.19% Cu, 4m at 0.70% Cu including 2m at 1.17% Cu, 3m at 0.30% Cu, 5m at 0.32% Cu and 1m at 1.23% Cu) have confirmed oxide and transitional mineralisation previously unidentified (Figure 6*).

The sub-parallel zone of supergene mineralisation was intercepted by hole 21NRSP024 (5m at 0.47% Cu including 1m at 1.36% Cu and 4m at 0.11% Cu). This hole also confirms sulphide mineralisation at depth (13m at 1.08% Cu including 1m at 1.12% Cu and including 3m at 3.10% Cu).

Section 102,960E

The drilling has confirmed oxide and transitional mineralisation previously identified in historical holes. New extensions to sulphide mineralisation to the east and at depth have also been identified (Figure 7*).

Hole 21NRSP035 confirms intercepts of shallow oxide and deeper transitional mineralisation (4m at 0.16% Cu, 7m at 0.16% Cu and 8m at 0.24% Cu).

Hole 21NRSP026 has intercepted the southern sub-parallel zone of supergene copper mineralisation (6m at 0.16% Cu). Sulphide mineralisation within the Nifty Syncline carbonate-shale host rocks was intercepted at depth (7m at 0.30%, 7m at 0.34% Cu and 4m at 0.20% Cu).

Sulphide mineralisation was intersected higher in the stratigraphic sequence in hole 21NRSP0025 (13m at 0.52% Cu including 1m at 1.48% Cu and including 1m at 2.13% Cu) and at depth (3m at 0.42% Cu and 4m at 0.19% Cu).

5 Best-performing Copper Stocks on the TSX in 2025

Copper prices have seen considerable gains in 2025, reaching a record high on the COMEX of US$5.68 per pound on July 8. Rising prices and supportive policy have elevated many copper stocks.

The price of copper has experienced volatility since the start of the year, as shifting US trade policy has created competing scenarios amid recession and the imposition of tariffs.

On July 8, the price spiked to fresh all-time highs after US President Donald Trump announced he would impose a 50 percent tariff on all copper being imported into the United States.

Top 5 ASX Copper Stocks of 2025

Copper has performed well in recent years, and prices for the red metal reached new record highs in July on US President Donald Trump's threats of 50 percent tariffs on copper imports.

The outlook for the red metal is positive in the short-term and there is plenty of optimism about copper over the longer term.

Many market watchers are forecasting robust copper prices, especially as low supply is coming up against higher usage from sectors such as the renewable energy and electric vehicle industries. Fastmarkets is predicting that copper demand from energy transition sectors should grow at a CAGR of 10.7 percent in the decade to 2034.

What Was the Highest Price for Copper?

Strong demand in the face of looming supply shortages has pushed copper to new heights in recent years.

With a wide range of applications in nearly every sector, copper is by far the most industrious of the base metals. In fact, for decades, the copper price has been a key indicator of global economic health, earning the red metal the moniker “Dr. Copper.” Rising prices tend to signal a strong global economy, while a significant longer-term drop in the price of copper is often a symptom of economic instability.

After bottoming out at US$2.17 per pound, or US$5,203.58 per metric ton (MT), in mid-March 2020, copper has largely been on an upward trajectory.
