Cabral Gold (CBR.V): Drills 46m @ 1.3 g/t gold and Defines Higher Grade Zone within the Gold-in-Oxide Blanket at the MG Target, Cuiú Cuiú District, Brazil
Vancouver, British Columbia–(Newsfile Corp. – November 24, 2021) – Cabral Gold Inc. (TSXV: CBR) (OTC: CBGZF) (“Cabral” or the “Company“) is pleased to provide assay results from an additional 20 RC holes at the MG gold-in-oxide blanket at the Cuiú Cuiú gold district in northern Brazil.
Highlights are as follows:
- Recent RC drilling at the MG gold-in-oxide blanket has defined a zone of higher grade gold mineralization extending at least 700m E-W. It directly overlies the underlying primary gold deposit in granitic rocks at MG
- Results have been received from 20 additional RC drill holes. These were designed to further test the extent and continuity of the MG gold-in-oxide blanket which overlies the primary MG gold deposit. Results include; 46m @ 1.3 g/t gold, 47m @ 0.7 g/t gold, 48m @ 0.5 g/t gold, 16m @ 1.2 g/t gold, 20m @ 0.8 g/t gold, and 14m @ 0.9 g/t gold
- These RC drill results from the MG gold-in-oxide blanket have increased the surface area of the blanket by a further 11% to 40 hectares. This represents a 100% increase to the initial estimated size of 20 hectares
- The gold-in-oxide blanket remains open in several directions and drilling of the higher-grade portions of the underlying MG primary gold deposit is in progress. Drilling is also in progress at the Central gold deposit and the PDM target
Alan Carter, Cabral’s President and CEO commented, “These RC drill results indicate that the recently identified gold-in-oxide blanket at MG contains a significant core of higher-grade gold mineralization and provide further evidence that we have a significant new discovery on our hands. The fact that it is located at surface within unconsolidated, oxidized soil and sediments would suggest that it is likely to be very important in terms of the overall economic viability of the Cuiú Cuiú gold district. We look forward to receiving additional RC results from MG and the results of the recently announced metallurgical work, as well as diamond drill results from the primary gold deposits at MG and Central, and drill results from the PDM and Alonso targets”.
MG Gold-in-Oxide Blanket RC Drilling
Following the discovery of an extensive gold-in-oxide blanket in near-surface unconsolidated material directly above the primary MG gold deposit in April of this year (see press release dated April 15, 2021 and Figure 1), Cabral has moved swiftly to define the limits to the gold-in-oxide mineralization (see press releases dated July 29, 2021, August 31, 2021, October 14, 2021 and November 9, 2021).

A total of 79 RC holes have been drilled to date to test the MG gold-in-oxide blanket. Results have been reported on a total of 69 RC holes including 20 holes which are reported herein.
Assay results have been received for holes RC207 through RC219, and RC230 to RC236 (Figure 2 and Table 1). Nearly all of these 20 holes returned intervals of gold-in-oxide mineralization within the overlying unconsolidated soils and sediments, and have expanded the surface footprint of the gold-in-oxide blanket at MG by a further 11% (to 40 hectares) from the most recent size estimate of 36 hectares (see press release dated November 9, 2021).

Furthermore, these recent tighter spaced RC drill results, together with previously reported results from the gold-in-oxide blanket, indicate the presence of a significant zone of higher grade gold mineralization within the blanket (Figure 3). This higher grade zone extends over at least 700m in an E-W direction and directly overlies the underlying primary gold deposit within granitic host rocks at MG.

The most significant intercepts from the recent RC holes reported here are as follows:
RC210 and RC211 were both drilled on section 553350. The section had no previous drilling and is located in the western central part of the gold-in-oxide blanket (Figures 2 and 4). RC210 is the northern-most hole drilled on the section and returned 46m @ 1.3 g/t gold from surface including 5m @ 3.6 g/t gold from 6m. This result lies within a E-W trending zone of higher grade gold mineralization in the gold-in-oxide blanket. RC211 was drilled approximately 45m to the south and intersected 14m @ 0.4 g/t gold from surface.

RC207, RC208 and RC209 were all drilled on section 553250 in the west central part of the gold-in-oxide blanket (Figures 2 and 5). RC209 was located in the center of the section and returned 47m @ 0.7 g/t gold from surface. RC208 was drilled approximately 30m north of RC209 and returned 48m @ 0.5 g/t gold from surface in the gold-in-oxide blanket. RC208 also intersected 40m @ 0.4 g/t gold in the underlying granitic rocks (Figure 5). RC207 is the southernmost hole on the section, and cut 8m @ 0.3 g/t gold from surface, suggesting the blanket thins to the south.

RC212, RC213 and RC214 were all drilled on section 552950 in the western part of the gold-in-oxide blanket (Figure 2). RC213 was the southernmost hole drilled on the section returned 14m @ 0.9 g/t gold from 13m depth as well as 7m @ 0.4 g/t gold from surface. Both intercepts are in the gold-in-oxide blanket, and indicate that the blanket is open to the south. RC213 also intersected 8m @ 0.5g/t gold from 46m depth in the underlying granite and ended in mineralization.
Drill holes RC215, RC216 and RC217 were all completed on section 553150 located in the central western part of the gold-in-oxide blanket at MG. RC216 returned 16m @ 1.2g/t gold from surface, while RC217 returned 12m @ 0.5 g/t gold from surface. Drilling on this section indicates that the gold-in-oxide blanket is still open to both the north and south.
Drill holes RC219, RC230, RC234 and RC235 were all completed at the eastern end of the gold-in-oxide blanket. RC234 returned 20m @ 0.8 g/t gold from 28m depth, including 4m @ 3.7 g/t gold, indicating that the blanket remains open to both the north and northeast.
The RC drilling program has been successful in delimiting and expanding an extensive, near surface zone of blanket mineralization at MG that was not previously recognized, and hence was largely not incorporated in previous resource estimates. Tighter drill spacing has also defined a higher grade east-trending zone within the blanket. All of this material would likely represent pre-strip for any pit exploiting the MG basement mineralization. This oxidized, unconsolidated material could be an important source of additional gold, particularly if it is amenable to lower cost heap leach processing (see also Cabral news release November 9, 2021).
Diamond drilling is ongoing at MG. While this program is designed to test for, and delimit, higher grade basement gold mineralization, these are deeper holes drilled from the north to south. It is possible that some of these diamond holes may encounter additional blanket mineralization as most of these drillholes will be collared in the saprolite sequence directly to the north of the currently defined blanket limits.
Assay results are still pending on an additional ten RC holes which have tested the blanket at MG.
