Vancouver, British Columbia–(Newsfile Corp. – March 13, 2025) – Cabral Gold Inc. (TSXV: CBR) (OTC Pink: CBGZF) (“Cabral” or the “Company”) is pleased to announce assay results from 2 surface trenches and 8 reverse circulation (“RC”) drill holes at the Machichie Main gold deposit within the Cuiú Cuiú Gold District, Brazil.
Highlights
Surface trench CT051 at the Machichie Main gold deposit at Cuiú Cuiú returned 20m @ 3.6 g/t gold including 4m @ 15.7 g/t gold in gold-in-oxide material at surface. The mineralized interval within the trench is open to the north and south. These results confirm the presence of significant higher-grade mineralization within the near surface gold-in-oxide material at the Machichie Main deposit Surface trench CT052, developed 150m west of trench CT051 also returned 7m @ 0.8 g/t gold. The mineralized interval is again open to the north and south RC drill results from Machichie Main include;
4m @ 3.9 g/t gold from 36m depth including 1m @ 10.6 g/t gold in RC4974m @ 3.1 g/t gold from 41m depth including 1m @ 10.6 g/t gold in RC4967m @ 1.5 g/t gold from 64m depth in RC4947m @ 1.2 g/t gold from 78m depth in RC4951m @ 9.9 g/t gold from 26m depth and 1m @ 7.3 g/t gold from 37m depth in RC503All of these intercepts were in fresh rock intrusive material below the near surface gold-in-oxide materialResults thus far from the trenches and initial drill holes confirm continuity and grade of the Machichie mineralization along strike and at depth Samples from the trenches are in the process of metallurgical testing to characterize the Machichie oxide zone
Alan Carter, Cabral’s President and CEO commented, “The current drilling and trenching program at Machichie Main is aimed primarily at upgrading the Inferred resource base within the near-surface gold-in-oxide zone to Indicated resources. These results confirm the presence of significant grades, both within the near-surface gold in-oxide material which comprises mineralized blanket sediments and saprolite (weathered bedrock), as well as the underlying fresh primary intrusive material at Machichie Main. The trench results in particular are significant because they confirm the presence of excellent grades within gold-in-oxide material at surface. This bodes very well for our efforts to upgrade the Inferred resources at Machichie Main as we work towards updating the results from the PFS study on an initial heap leach starter operation previously released in October 2024.”
Machichie Main Trench and Drill Results
The Machichie Main zone is an E-W trending zone of gold mineralization which is located 500m north of the MG gold deposit (Figure 1). As with the MG and Central gold deposits, the zone of primary mineralization within intrusive rocks is overlain by an extensive weathered layer consisting of near-surface sediments and underlying saprolite (weathered intrusive rock). Both types of material are considered gold-in-oxide material. A preliminary Inferred resource estimate of 3.73Mt @ 0.5 g/t gold was calculated for the gold-in oxide material only at Machichie Main and was released in October 2024 (see press release October 21, 2024).
The main objective of the current program is to upgrade a significant portion of the current Inferred resources to Indicated status so they can be included in the mine plan for the heap-leach starter operation. The current program of drilling and trenching is also aimed at shedding light on the underlying primary mineralized zone in the intrusive rocks and collecting additional material for a series of metallurgical column-leach tests.
Four trenches have been developed recently at Machichie Main to obtain samples for metallurgical testing and further define mineralization in the oxide zone. Results have been received on 2 (CT051 and CT052) of the 4 trenches to date. Trench CT051 was excavated over the central part of the Machichie Main gold deposit, over an interval of 20m and returned 20m @ 3.6 g/t gold including 4m @ 15.7 g/t gold in weathered gold-in-oxide saprolite material (Figures 2 and 3). Mineralization is open to the north and south.
The mineralized zone cut in trench CT051 is almost certainly the same mineralized zone cut at depth in drill holes DDH279 (16.6m @ 1.9 g/t gold including 1m @ 29.7 g/t gold), DDH300 (15.7m @ 1.6 g/t gold) and DDH301 (12.2m @ 1.4 g/t gold) (Figure 3).
Trench CT052 was excavated 150m west of trench CT051 and returned 7m @ 0.8 g/t gold (Figure 2). The mineralized interval is again open to the north and south.
These results confirm the presence of significant high-grade gold mineralization within gold-in-oxide material at Machichie Main and bode well for the possible inclusion of additional Indicated resources from Machichie Main into an updated mine plan for the heap leach starter operation at Cuiu Cuiu. Results are currently pending from two additional trenches at Machichie Main CT053 and CT054.
Results were received on 8 RC drill holes (RC494 to RC498, RC500 to RC501 and RC503) at Machichie Main which were all drilled on the margins of the gold-in-oxide zone to determine the extent of the near-surface mineralization. All of the holes intersected multiple zones of mineralization (Table 1, Figure 2).
Several of the holes cut significant intercepts within the gold-in-oxide material, e.g. 10m @ 0.42 g/t gold from surface in RC497. However, a number of excellent results were returned from the underlying primary intrusive material including 4m @ 3.9 g/t gold including 1m @ 10.6 g/t gold in RC497 and 4m @ 3.1 g/t gold including 1m @ 10.6 g/t gold in RC496. Other notable results included 7m @ 1.5 g/t gold from RC494, 7m @ 1.2 g/t gold from RC495, and 1m @ 9.9 g/t gold and 1m @ 7.3 g/t gold from RC503.
Holes RC496 and RC497 were drilled 50m apart and intersected the same mineralized zone along strike with similar grades and thicknesses. Similarly, the mineralization intersected in holes RC494 and RC495 is the same zone again returning similar grades and thicknesses along strike. Thus far the infill drilling at Machichie has confirmed continuity of grade and thicknesses along strike and at depth into the primary intrusive, affirming potential to upgrade the Inferred resources.
