Vancouver, British Columbia--(Newsfile Corp. - February 13, 2025) - Cabral Gold Inc. (TSXV: CBR) (OTC Pink: CBGZF) ("Cabral" or the "Company") is pleased to provide a summary of recent progress at the Cuiú Cuiú gold district in northern Brazil.
Highlights
- Two drill rigs are currently operating at Cuiú Cuiú. One of these rigs is working on upgrading gold-in-oxide Inferred resources to Indicated status at the Machichie Main target which was not considered in the PFS announced in October 2024, but is likely to form part of an updated mining plan
- The second rig is focused on follow-up drill testing of primary exploration targets at the Machichie NE discovery, where drilling in 2024 returned 11m @ 33 g/t gold (see press release dated May 30, 2024), and also at the Central SE, Mutum and Jerimum Cima targets. Results are currently pending on 18 holes from both rigs
- Ausenco Brazil has been contracted to update the PFS on the initial heap leach starter operation, particularly with a focus on capturing the opportunities identified in the PFS to lower the estimated capital and operating expenditures as well as increasing the mining rate and plant capacity. Discussions regarding project financing and ECPM (Engineering, Construction and Procurement Management) contracts are ongoing
- Mine plan scenarios are being run using economic and operating assumptions more aligned with an increased scale, the latest unit costs and the projected gold price environment. This may drive a reduction in the cut-off grade and could further increase mineral reserves across all three deposits (MG, Central and Machichie Main)
- Cabral has hired John Sestan as VP Project Development to oversee and manage the gold-in-oxide heap-leach starter operation at Cuiú Cuiú and to build potential development options aligned with increasing the global resource base
Alan Carter, Cabral's President and CEO commented, "The next few months should be very exciting for our shareholders as we continue to develop our heap-leach starter operation at Cuiú Cuiú with the objective of achieving near-term cash flow. Once in operation, this starter project will allow us to aggressively drill off the numerous targets within the Cuiú Cuiú district and significantly expand the global resource inventory.
Recent optimization work by our team has confirmed potential savings in capital expenditures and operating expenditures for the gold-in-oxide project. In addition, the current drilling program is aimed at further increasing the Indicated resource base which we expect will support the inclusion of gold-in-oxide material from the Machichie Main deposit. The appointment of John Sestan as VP Project Development is another important step in our transition from a pure exploration company to a junior producer.
In parallel with the advances on our heap leach starter operation, we have also commenced exploration drilling on several high-priority targets in close proximity to the known gold deposits, including Central SE, Mutum, Jerimum Cima and the Machichie NE discovery where drilling in 2024 returned 11m @ 33 g/t gold."
Drilling
Cabral is currently operating two reverse circulation (RC) drill rigs along with two excavators for trenching and road construction. Presently, one RC rig is conducting infill drilling on the Machichie Main deposit in order to increase drill spacing and upgrade Inferred to Indicated gold-in-oxide resources. This could positively impact the resources considered in the mine plan and the reserves.
A second RC rig is conducting further exploration on the Machichie NE zone where Cabral drilled high grade intercepts of 5m @ 24.5 g/t Au (DDH331), 11m @ 33.0 g/t Au (RC421), and 6m @ 13.3 g/t Au (RC449) in 2024 (see press releases dated May 30, July 25 and October 28, 2024). The high-grade zone at Machichie NE has thus far been traced for 200m along strike in a NW-SE direction. A recent reinterpretation of the airborne geophysical data suggests this structure may extend at least 600m along strike.
Cabral is planning exploration drilling on several other targets within the Cuiú Cuiú district during Q1 2025. As with Machichie NE, this program is aimed at making another significant hard rock discovery and adding further to the global resource base within the district.
A series of holes are planned at the Central SE target in the coming weeks, where previous recce drilling hit 27m @ 6.9 g/t gold, and a major soil geochemical anomaly suggests a potential extension immediately southeast of the Central gold deposit.
The company also plans drilling and trenching at the Jerimum Cima target to follow up on 2024 trench results of 18m @ 1.9 g/t gold (see press release dated November 14, 2024 and several older diamond drill holes that intercepted significant gold mineralization including 39m @ 5.1 g/t gold in primary intrusive rocks.
At Pau da Merenda (PDM), mineralization remains open at depth and to both the northwest and southeast towards the Mutum area where historic surface trenching returned values including 32m @ 1g/t gold, 25.5m @ 0.9g/t gold and 16.5m @0.9 g/t gold. Cabral plans drilling in the coming weeks and months to test each of these targets.
Drill results are currently pending on 18 holes.
Ongoing Work Regarding Heap-Leach Starter Operation
Cabral has contracted Ausenco Brazil to complete an updated PFS study on the gold-in-oxide material at Cuiú Cuiú, the results on which are expected during Q2. The results of the PFS study on the gold-in-oxide starter operation included an after-tax IRR of 47.3% and after-tax NPV5 of US$25.2 million for an initial 720,000 tonne / yr starter operation using open-pit mining of oxidized gold mineralization and heap-leach processing, and assuming a gold price of US$2,250 / oz. The development capex was estimated at US$37.4 million. At the spot gold price on October 21, 2024 of US$2,710/oz, the after-tax IRR increases to 82.6% and the after-tax NPV5 to US$49.3 million (see press release dated October 21, 2024).
Recent optimization work has confirmed a number of potential cost savings, particularly the estimated capital and operating expenditures, as well as potential to increase the mining rate and plant capacity.
Furthermore, the additional drilling currently in progress at Machichie Main and drilling completed at the Central gold deposit following the release of the PFS study could result in the conversion of a significant portion of the Inferred gold-in-oxide resources to Indicated resources, which will be incorporated in an updated resource estimate for the gold-in-oxide material at Cuiú Cuiú. This in turn will result in an amended mineral reserve estimate and mine plan, also expected as part of an updated PFS during Q2 2025.
Additional metallurgical work, including a number of column leach tests, is also planned at the Kappes Cassiday and Associates lab in Reno, Nevada, and is aimed at characterizing the gold-in-oxide material from the Machichie Main gold deposit. These metallurgical results are expected in Q2 2025.
Mine plan scenarios are being run using economic and operating assumptions more aligned with an increased scale, the latest view of unit costs and the projected gold price environment. This may drive a reduction in the cut-off grade and should further increase mineral reserves across all three deposits (MG, Central and Machichie Main).
Discussions regarding ECPM (Engineering, Construction and Procurement Management) contracts, and project financing are ongoing.
