Cabral Gold Inc. (TSXV: CBR) (OTC Pink: CBGZF) is pleased to provide assay results from eight RC holes and three diamond-drill holes at the primary MG gold deposit, and within the recently identified gold-in-oxide blanket within the Cuiú Cuiú gold district in northern Brazil.
Highlights are as follows:
Alan Carter, Cabral’s President and CEO commented, “The results that we are reporting today from the recent diamond drilling at MG suggest that historic drilling in the western part of the primary MG gold deposit failed to intercept the main mineralized zone. The new mineralized intercept in RC237 is very significant and could add ounces in the western part of the primary MG gold deposit. Furthermore, the results from the initial metallurgical test hole within the overlying MG gold-in-oxide blanket, suggest that the higher grade portions of the blanket may be even higher grade than we previously envisaged.”
MG Diamond Drilling
Assay results were returned on three diamond-drill holes recently completed at the MG gold deposit (MET01, DDH233A and DDH242). MET01 is one of five holes drilled to provide material from the gold-in-oxide blanket for metallurgical test work (see press release dated November 9, 2021) (Figure 1). Assay results from the remaining four MET holes are pending.
Figure 1: Map showing the outline of the primary MG gold deposit (in pale yellow) and the interpreted outline of the overlying mineralized oxide blanket (in beige). The results from recently completed diamond drill holes (MET01, DDH233A and DDH242) and RC drill holes (RC237, RC238, RC239, RC260, RC261, RC263, RC264 and RC266) are also shown.
Diamond-drill hole MET01 was drilled on section 553300 located in the central western portion of the gold-in-oxide blanket at MG (Figure 1). It was sited approximately 20m south of RC66 which returned 15m @ 0.6 g/t gold, and 20m north of RC65 which returned 51m @ 0.8 g/t gold (Figure 2). MET01 was expected to return similar gold grades.
However, MET01 actually returned 30m @ 2.2 g/t gold from surface including 8.2m @ 6.6 g/t gold from 2.8m depth (Figure 2). These were significantly higher gold grades than anticipated based on previous results from RC65 and RC66.

MG RC Drilling
RC drill hole RC237 was drilled on section 552900 located in the western part of the MG gold deposit (Figure 1). Only one hole had previously been drilled on this section. Historic diamond-drill hole CC49 was drilled from north to south and cut a narrow zone of gold mineralization which returned 5m @ 1.9 g/t gold. More recent drilling at MG has confirmed that the primary basement MG gold deposit dips to the north, implying that CC49 may have been drilled sub-parallel to the dip of the deposit, and potentially too far to the north.
Two RC holes were drilled to test this possibility. RC191 returned 7m @ 0.5 g/t gold in the footwall, i.e. south of the historic intercept of 5m @ 1.9 g/t gold returned in CC49 (Figure 3). RC191 ended in mineralization and suggested the presence of a new mineralized zone. RC237 was drilled below RC191 to test this possibility and returned 19.1m @ 2.2 g/t gold from 85.0m depth, including 7.0m @ 4.5 g/t gold (Figure 3). The hole ended in mineralization and the zone remains open. This intercept is now interpreted to be the western extension of the main mineralized zone at the primary MG gold deposit, and has significant implications for the continuation of the main mineralized zone further west.

Drill hole RC260 was drilled on section 554180 near the eastern limit of the primary MG deposit and well beyond the eastern limit, as it is currently known, to the overlying gold-in-oxide blanket (Figure 1). RC0260 was also located 60m west of historic diamond-drill hole CC100 which returned 5m @ 17.9 g/t gold. A single historic drill hole (CC111) on this section returned 3m @ 0.5 g/t gold and 7.2m @ 0.6 g/t gold. Hole RC260 returned 8m @ 3.1 g/t gold from 84.0m depth including 2m @ 11.7 g/t gold from 89.0m depth, and 4m @ 2.3 g/t gold from 111.0m depth including 1m @ 8g/t gold from 113.0m depth (Figure 4). These results indicate the extension of the high-grade gold mineralization intersected in CC100 further to the east and nearer surface.

Diamond drilling at MG is continuing with results pending on an additional nine diamond drill holes.
Diamond drilling is continuing at the primary Central gold deposit. The seventh hole is currently in progress from a total program of 43 planned diamond-drill holes. These are designed to further define the high-grade zones at Central. Previous diamond drilling at Central included 220.7m @ 2.0 g/t gold including 9.8m @ 17.9 g/t gold.
RC drilling at Central is in progress with the objective of testing for the presence of gold-in-oxide blanket mineralization above the primary Central gold deposit. Results are currently pending on seven holes.
Diamond drilling continues at the PDM target, located 2.5km NW of the Central gold deposit, and is aimed at testing for the presence of a primary gold deposit in the basement intrusive rock underlying the gold-in-oxide blanket. Results are currently pending on six diamond-drill holes.
Results are currently pending on five diamond-drill holes at the Alonso target which is located 3km SE of the MG gold deposit. Twenty-three samples of boulder float material from Alonso previously returned gold values of 11.6 to 200.3 g/t gold (see press release dated February 11, 2020).
Geosedna has completed the 10,000m RC drilling contract and drilling with the large RC rig has been suspended as a result of the onset of the rainy season. Drilling will continue with the four other drill rigs currently on site.
