Vancouver, British Columbia--(Newsfile Corp. - December 14, 2023) - Cabral Gold Inc. (TSXV: CBR) (OTC Pink: CBGZF) ("Cabral" or the "Company") is pleased to announce drill results from an additional ten RC holes from the Central gold deposit that are part of the ongoing drill program currently being conducted at both the Central and MG gold deposits within the Cuiú Cuiú gold district in northern Brazil.
Highlights
- Notable drill intercepts from the ten RC holes delineating the Central gold-in oxide blanket and basement saprolite include RC365 which returned 28m @ 1.2 g/t gold from 29m depth in saprolite, including 2m @ 6.5 g/t gold
- RC367 returned 35m @ 0.8 g/t gold from 35m depth in saprolite including 10m @ 1.1 g/t gold
- RC366 was drilled on the same section as RC367 and returned 30m @ 0.6 g/t gold from 21m depth in saprolite including 8m @ 1.4 g/t gold, and intersected 8m @ 1.7 g/t gold from 56m
- RC359 returned 7m @ 2.3 g/t gold from 32m depth in saprolite including 1m @ 12.8 g/t gold
Alan Carter, Cabral's President and CEO commented, "These drill results from the near-surface gold-in-oxide blanket and saprolite material at the Central gold deposit further demonstrate the presence and continuity of higher-grade material located near surface. These results continue to bode well for the optimization of the resource model of the known gold-in-oxide resources at Cuiú Cuiú during the coming months."
Central RC Drill Results
The Central gold deposit is one of the two main gold deposits identified to date at Cuiú Cuiú. As with the nearby MG gold deposit, the upper portion of the Central gold deposit is extensively weathered resulting in a vertical profile of approximately 60m on average of highly weathered basement saprolite. The weathered mineralized basement saprolite is overlain by mud, soil and colluvium material which forms a blanket. All of the blanket material contains gold and is derived from the chemical and physical weathering the underlying saprolite basement gold mineralization.
Whilst, the bulk of the gold resources at Central are contained within the underlying primary (un-weathered) basement material (see the NI 43-101 report dated effective July 31, 2022), the overlying oxide material currently contains Indicated Resources of 3.49Mt @ 0.6 g/t (65,400oz) and Inferred Resources of 3.36Mt @ 0.4 g/t (44,800oz). A significant amount of higher-grade material (greater than 1.75g/t gold) is contained within these resources and the current drill program at Central is designed to expand and delimit these resources within the near-surface saprolite and blanket material.
Holes RC358 to RC367 were all drilled within the overall outline of the oxide resource at Central to a maximum depth of 97m (Figure 1).

Section N20995
Drill hole RC365 was drilled on section N20995 in the southern part of the Central deposit (Figures, 1 and 2, Table 1). The hole was designed to establish up-dip continuity of the higher-grade zone of mineralization intersected in diamond hole DDH255 which previously returned 37m @ 1.3 g/t gold.
Hole RC365 intersected 28m @ 1.2 g/t gold from 29m depth in saprolite, including 2m @ 6.5 g/t gold from 30m depth. This zone is interpreted as the up-dip extension of the significant zone of mineralization previously intercepted in weathered basement (saprolite) in DDH255, and historic hole, CC13, which cut 48.1m @ 4.5 g/t gold, providing excellent evidence of continuity in the near-surface oxide material. This higher-grade zone has been traced to depth in the underlying un-weathered basement rocks. RC365 ended at 59m in gold-in-oxide mineralization within weathered basement (saprolite), with the last 2m from 57m ending in mineralized material and averaging 1.2 g/t gold.

Note that the drill intercept of 28m @ 1.2 g/t gold is up-dip from the intersection in diamond-drill hole DDH255 which returned 37m @ 1.3 g/t gold and that in diamond-drill hole CC13, which cut 48.1m @ 4.5 g/t gold. Terms; g/t = grams / tonne, m = metres, ppm = parts per million or grams / tonne
Section N20945
Holes RC366 and RC367 were both drilled on section N20945 (Figures 1 and 3, Table 1).
RC367 was drilled from the north-east towards the south-west and returned 35m @ 0.8 g/t gold from 35m depth in saprolite including 10m @ 1.1 g/t gold. The hole also returned 4m @ 0.3 g/t from surface in blanket sediments and 5m @ 0.5 g/t from 22m in saprolite. The intervening interval returned no sample during drilling but based on previous results from DDH283 and DDH284, it is almost certainly mineralized.
RC366 was drilled on the same section from the same platform as RC367 and returned 30m @ 0.6 g/t gold from 21m depth in saprolite including 8m @ 1.4 g/t gold. The hole also intersected 8m @ 1.7 g/t gold at depth from 56m to the end of hole at 64m. As with hole RC367, no material was recovered in the upper portion of the hole from 5 to 21m.
The two new holes add further confidence to the previous interpretation that mineralized zones extend upward from un-weathered basement rocks through the weathered basement (saprolite).

Section N21243
Holes RC358 and RC359 were both drilled on section N21243 (Figures 1 and 4, Table 1). RC359 was drilled from the south-west towards the north-east and intersected 7m @ 2.3 g/t gold from 32m depth including 1m @ 12.8 g/t gold in saprolite material.
RC358 was drilled in the same direction as RC359 but was collared 50m to the north-east and cut several zones of mineralization in saprolite material including 1m @ 4.8 g/t from 26m depth, 3m @ 1.3 g/t from 52m depth and 1m @ 2.0 g/t from 60m depth.
No previous drilling had been conducted on this section.

These drill results, and those that are pending, will allow the generation of a more accurate resource model of the oxide mineralization at Central and MG which will form the basis of a proposed mine plan for trial mining. The prefeasibility study on trial mining of the gold-in-oxide resources will consider the exploitation by open-pit mining and heap-leach processing.
Drilling at Cuiú Cuiú is ongoing with results still pending on 21 RC holes from Central and nine shallower power-auger holes at MG. Results are also pending on 18 RC holes from the Machichie target, which is located approximately 500m north of the MG gold deposit.
Term loan
Cabral also announces that the term loan with Dr. Alan Carter, President and CEO of the Company, has been repaid in full with the exception of interest accrued from October 1, 2023 (see news release dated March 7, 2023).
About Cabral Gold Inc.
The Company is a junior resource company engaged in the identification, exploration and development of mineral properties, with a primary focus on gold properties located in Brazil. The Company has a 100% interest in the Cuiú Cuiú gold district located in the Tapajós Region, within the state of Pará in northern Brazil. Two main gold deposits have so far been defined at the Cuiú Cuiú project which contains National Instrument 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) as per the 43-101 technical report dated October 12, 2022.
The Tapajós Gold Province is the site of the largest gold rush in Brazil's history which according to the ANM (Agência Nacional de Mineração or National Mining Agency of Brazil) produced an estimated 30 to 50 million ounces of placer gold between 1978 and 1995. Cuiú Cuiú was the largest area of placer workings in the Tapajós and produced an estimated 2Moz of placer gold historically.
