- Cabral Gold has extended its RC drilling program at the Cuiú Cuiú gold district in Brazil following successful recent drilling that targeted higher-grade near-surface oxide material at the Central and MG gold deposits.
- The expanded drill program will test several additional exploration targets, including Machichie Main, Machichie NE, Machichie West, Pau da Merenda, Baixao da Onca, and Mutum, with the goal of expanding oxide resources.
- Results from the current drill program are being used to update resource models for the ongoing Pre-Feasibility Study (PFS) on trial mining and heap leach processing of the near-surface oxide material.
- Cuiú Cuiú hosts NI 43-101 compliant Indicated resources of 21.6Mt @ 0.87 g/t gold (604,000 oz) and Inferred resources of 19.8Mt @ 0.84 g/t gold (534,500 oz) across two main deposits.
- The Cuiú Cuiú project is located in the Tapajós region, the largest gold rush site in Brazil's history that produced an estimated 30-50Moz of placer gold. Cuiú Cuiú itself produced ~2Moz of this placer gold historically.
About Cabral Gold
Cabral Gold Inc. (TSXV:CBR) is a junior resource company focused on gold exploration and development in Brazil. The company's flagship asset is a 100% interest in the Cuiú Cuiú gold district located in the Tapajós region of Pará state in northern Brazil.
Cuiú Cuiú currently hosts National Instrument 43-101 compliant Indicated resources of 21.6Mt grading 0.87 g/t gold (604,000 ounces) and Inferred resources of 19.8Mt grading 0.84 g/t gold (534,500 ounces) across two main gold deposits. Notably, the Cuiú Cuiú district sits within the Tapajós Gold Province, the largest gold rush site in Brazil's history that produced an estimated 30-50 million ounces of placer gold between 1978-1995. Cuiú Cuiú itself was the largest area of historical placer workings in the Tapajós and produced approximately 2 million ounces of this placer gold.
Extended RC Drill Program
Cabral recently announced an extension and expansion of the ongoing Reverse Circulation (RC) drilling program at Cuiú Cuiú. The decision follows encouraging results from recent drilling targeting higher-grade, near-surface gold mineralization within oxidized blanket and saprolite material at the Central and MG deposits.
Since August 2023, Cabral has completed 78 RC holes at Central, MG, and the Machichie target using a company-owned RC rig. Notable results include:
- 27m @ 1.9 g/t gold at MG
- 16m @ 5.2 g/t gold at Central
- 30m @ 2.6 g/t gold at Machichie
The results are currently being incorporated into updated resource models that will support mine planning as part of the ongoing Pre-Feasibility Study (PFS) on trial mining and heap leach processing of the near-surface oxide resources.
Given the positive drill results, especially from Machichie where there is no current resource due to limited previous drilling, Cabral has decided to extend and expand the RC program. The expanded program will test several highly prospective targets in addition to further drilling at Machichie, Machichie NE, Pau da Merenda and Jerimum Baixo. Previously untested targets including Machichie West, Baixao da Onca and Mutum will also be drilled.
Key Targets in Expanded Program
Machichie Main: Located just 500m north of the MG deposit, previous drilling and trenching at Machichie identified a 900m long E-W trending mineralized zone parallel to MG. Prior results include drill intercepts of 34m @ 5.4 g/t, 6.4m @ 11.6 g/t, 45m @ 1.0 g/t and 62.8m @ 0.9 g/t gold, and trench intervals of 5m @ 8.3 g/t and 9.5m @ 5.3 g/t gold. The recent 30m @ 2.6 g/t gold intercept in saprolite suggests potential for distinct higher-grade zones extending into underlying bedrock. Additional drilling will aim to better define these zones.
Machichie NE: Situated 200m northeast of Machichie Main, limited previous drilling returned 8m @ 3.3 g/t gold in fresh basement rocks and 9m @ 2 g/t gold in blanket material. Mineralization remains open to the east and at depth. The weathering profile suggests up to 60m of saprolite at Machichie NE.
Machichie West: A previously undrilled target hosting a potential sheeted vein system. Surface trenching returned long intervals of 96.5m @ 0.6 g/t and 138m @ 0.5 g/t gold over an area of 300m x 500m.
Pau de Merenda: A broad mineralized zone 1km northwest of the Central deposit that hosts an inferred oxide resource. Highlighted drill results include 47.1m @ 1.8 g/t, 8.5m @ 5.1 g/t, 40m @ 2.2 g/t, 46m @ 1.2 g/t, and 13m @ 4.6 g/t gold. The zone remains open along strike and at depth.
Mutum: An undrilled target 600m southeast of Pau de Merenda where surface trenches returned 32m @ 1g/t, 25.5m @ 0.9 g/t and 16.5m @ 0.9 g/t gold in weathered stockwork veins.
Baixao da Onca: Located 1.5km east of the MG deposit along the main TZ lineament, surface trenching of a weathered vein system yielded 14.7m @ 2.6 g/t gold. Also previously undrilled.
The expanded RC drilling is already underway and anticipated to continue for several months.
Ongoing PFS on Oxide Resources
In parallel with the drilling, Cabral is completing a Pre-Feasibility Study (PFS) with Ausenco Brazil to evaluate the economics of trial mining and heap leach processing of the near-surface oxide resources at Cuiú Cuiú. An update on the PFS is expected in the coming weeks.
The current drill program is a key input to the PFS, with results being used to update resource models underpinning mine planning. The aim is to better define and expand the higher-grade portions of the oxide resources in the near-surface saprolite and blanket material at MG and Central to improve confidence and optimize mine sequencing.
Exploration Upside
While the immediate priority is completing the oxide PFS, the expanded RC drill program highlights the substantial exploration upside at Cuiú Cuiú. As noted by Cabral's President and CEO Alan Carter:
"It is clear that significant upside to the current oxide resources exists at a number of other targets within the Cuiú Cuiú district. The extension of the current drill program will also test several previously untested targets within the district and provide a steady flow of drill results in the coming months."
Newly appointed VP Exploration Brian Arkell added:
"I'm very impressed with the sheer number of high-quality exploration targets on the Cuiú Cuiú property. We have a very solid pipeline of prospects for early-stage exploration as well as several drill-ready targets to potentially add resources... At the same time, we will be conducting more detailed geophysics, further sampling programs, and a comprehensive structural study as part of our district and regional exploration plans to produce the next generation of drill targets."
This speaks to both the prospectivity of the broader Cuiú Cuiú district and Cabral's plans to accelerate exploration alongside the ongoing PFS work. With numerous untested or underexplored targets, there is good potential to expand the oxide resources and make new discoveries.
The Tapajós: An Emerging Gold District
The Cuiú Cuiú project's location within the Tapajós Gold Province provides important geological context for Cabral's exploration upside. As noted, the Tapajós region was the site of the largest gold rush in Brazil's history, producing an estimated 30-50 million ounces of placer gold between 1978-1995.
Cuiú Cuiú itself was the largest garimpo (artisanal mining site) in the Tapajós and the source of approximately 2 million ounces of this placer gold production. The presence of substantial historical placer gold workings is a strong indicator of the hard rock potential at Cuiú Cuiú.
Moreover, the recognition of the Tapajós as an emerging gold district on par with other major Brazilian gold camps bodes well for Cabral. Major and mid-tier gold miners are increasingly focused on the region, drawn by its prolific gold endowment and untapped potential.
Cabral's Cuiú Cuiú project, with its established oxide resource base and compelling exploration upside, is well positioned to benefit from growing interest and investment in the Tapajós. The company's first-mover status and 100% ownership of the district-scale land package are key competitive advantages.
Conclusion
Cabral Gold offers a compelling investment opportunity in the junior gold space. With a robust near-surface oxide resource base at Cuiú Cuiú and an ongoing PFS evaluating trial mining and heap leach processing, the company is positioning itself as a potential near-term gold producer.
At the same time, Cabral is embarking on an aggressive exploration push to expand the oxide resources and test multiple high-potential targets across the broader Cuiú Cuiú district. The expanded RC drill program, underpinned by the recent oversubscribed financing, will provide steady news flow and has already delivered encouraging results from Machichie.
The company's 100% ownership of the district-scale land package within the Tapajós Gold Province is another key differentiator. As the site of Brazil's largest historical gold rush, the Tapajós is re-emerging as a major gold district and attracting growing attention from larger miners. Cabral's first-mover advantage and control of the most prospective and historically productive part of the Tapajós positions it to create significant value with exploration success.
With the ongoing PFS on track and an expanded drill program underway to grow the resource base and make new oxide discoveries, Cabral is entering an exciting period in its evolution. Investors can look forward to a steady stream of catalysts in the months ahead as the company advances Cuiú Cuiú towards potential production while systematically unlocking the district's exploration potential.
