Cabral Gold Inc. (TSXV: CBR) (OTC PINK: CBGZF) is pleased to provide additional assay results from nine recently completed diamond drill holes in the primary bedrock 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 drill results that we are reporting today from the diamond drilling at MG further extend the main mineralized zone at depth and confirm the presence of a significant mineralized zone within the footwall to the primary MG gold deposit. Both zones remain open at depth. The down-dip continuation of a significant mineralized zone in the footwall to the MG deposit is very encouraging. Elsewhere at MG, the recent diamond drilling is corroborating the recent RC drill results and suggesting that the gold-in-oxide blanket at MG, which overlies the primary MG gold deposit, will continue to grow.”
MG Diamond Drilling
Assay results were returned on nine additional diamond drill holes (DDH221 to DDH229) which were recently completed at the MG gold deposit (Figure 1). The current diamond-drill program is designed to define the limits to the high-grade zones within the existing MG and Central deposits at Cuiú Cuiú.

The results from recently completed diamond drill holes (DDH221 – DDH229) are also shown. Note that DDH225 returned no significant results
Holes DDH228 and DDH229 were both drilled on the same section (553610) located in the central eastern portion of the primary MG gold deposit (Figures 1 and 2). The holes were designed to follow up on previous holes drilled in the same section such as DDH202 which returned 14.2m @ 6.7 g/t gold (see press release dated January 20, 2020) and DDH215 which intersected 17.6m @ 4.1 g/t gold and 18.1m @ 4.3 g/t gold (see press release dated July 8, 2021). DDH215 is of particular significance because it indicates the presence of a new mineralized zone (18.1m @ 4.3 g/t gold) within the footwall to the main mineralized zone at MG.
DDH228 was drilled down dip of DDH215. It returned 9.1m @ 1.1 g/t gold from 187.9m depth and 14m @ 1.9 g/t gold from 208.6m depth including 2.5m @ 7.5 g/t gold (Figure 1). This intercept is the down-dip continuation of the main mineralized zone at MG intersected in hole DDH215 which returned 17.6m @ 4.1 g/t gold including 1.3m @ 29.5 g/t gold. The footwall zone returned lower grade intervals including 7m @ 0.6 g/t gold, but suggests continuity of the zone at depth.
DDH229, drilled on the same section as DDH228, returned 10.5m @ 2.4 g/t gold from 258.5m depth, including 2m @ 4.7 g/t gold, and 2.6m @ 2.8 g/t gold from 246.1m depth including 0.9m @ 7.1 g/t gold (Figure 2). These intercepts represent the down-dip continuation of the main mineralized zone at MG. The hole also intersected 8.8m @ 0.5 g/t gold from 292.8m depth and 9.2m @ 0.4 g/t gold from 310.5m depth. Both the main mineralized zone at MG and the footwall zone remain open at depth.

DDH226 and DDH227 were drilled on section 553745 to test the north-eastern continuation of the gold-in-oxide blanket (Figure 3) and both holes intersected significant thicknesses of gold mineralization within the overlying gold-in-oxide blanket. Recent RC drilling on this section returned 66m @ 0.7 g/t gold in hole RC157 from 1.0m depth (see press release dated October 14,2021). DDH226 and DDH227 were drilled 100m north of RC157. DDH226 intersected 22m @ 0.3 g/t gold from surface, while DDH227, which was drilled from the same collar, intersected 17m @ 0.3 g/t gold from 4.0m depth. These results indicate that the gold-in-oxide blanket remains open to the north-east.
Both DDH226 and DDH227 also intersected the main primary MG mineralized zone at depth (Figure 3). DDH226 returned 11m @ 0.4 g/t gold from 157m depth. DDH227, which was drilled further down dip returned 3m @ 1.3 g/t gold from 183m depth, 8m @ 0.8 g/t gold from 202m depth and 9m @ 0.4 g/t gold from 216m depth. These results indicate the continuation of the main mineralized zone at depth.
Diamond drilling at MG continues with results pending on an additional nine diamond drill holes.

No significant results were returned for DDH225
Miraboa Reconnaissance RC Drilling
Results were returned on 30 shallow reconnaissance holes at the Miraboa target which is located 2.8km south of the Central gold deposit and is the site of extensive and as yet unexplained historic placer gold workings.
Two of the reconnaissance RC holes intersected low grade but significant gold values near surface, including RC182 which returned 17m @ 0.35 g/t gold from surface, and RC128 which intersected 8m @ 0.2 g/t gold (Figure 4). The presence of gold in these two holes may indicate the presence of a near surface gold-in-oxide blanket similar to those identified at the PDM target and above the MG gold deposit, but the bulk of the placer gold extracted from the E-W trending drainage at Miraboa remains unexplained. Further drilling will be required.

Central Diamond and RC drilling
Following the recent commencement of follow-up diamond drilling at the primary Central gold-deposit (see press release dated October 28, 2021), which is aimed at further defining the high-grade zones at Central, RC drilling has also commenced aimed at testing for the presence of gold-in-oxide blanket mineralization above the primary Central gold deposit. A program of approximately 43 diamond drill holes and 26 RC holes are planned.
PDM (Pau de Merenda) diamond drilling
Diamond drilling is continuing 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 pending on five diamond-drill holes.
MG RC drilling
Results are currently pending on 44 RC holes at MG designed to test the extent of the gold-in-oxide blanket.
Alonso Reconnaissance Diamond Drilling
Results are currently pending on five diamond drill holes which is located 3km SE of the MG gold deposit. Twenty-three samples of this boulder float material previously returned gold values of 11.6 to 200.3 g/t gold (see press release dated February 11, 2020).
