Gold Stock News: Cabral Gold (TSXV: CBR) Drills 17.5m @ 4.0 g/t Gold at MG within the Cuiu Cuiu Gold District


Vancouver, British Columbia – April 21, 2022 (Newsfile Corp.) ( Newswire) Cabral Gold Inc. (TSXV: CBR) (OTC PINK: CBGZF) (“Cabral” or the “Company”) is pleased to provide assay results from six diamond-drill holes testing the MG gold deposit within the Cuiu Cuiu gold district in northern Brazil.

Highlights are as follows:

DDH272 intersected 17.5m @ 4.0 g/t gold within the primary hard-rock MG gold deposit from 102.9m, including 5.5m @ 10.5 g/t gold from 104.1m. The hole also cut a significant interval in the overlying unconsolidated sediments that comprise the gold-in-oxide blanket returning 44.0m @ 0.5 g/t gold from surface
DDH273 returned 18m @ 1.0 g/t gold in unconsolidated sediments that comprise the gold-in-oxide blanket, which included 1m @ 15.3 g/t gold
DDH285 encountered a significant mineralized interval within primary hard-rock material returning 31.0m @ 1.3 g/t gold from 105.0m, including 0.5m @ 15.5 g/t gold from 106.0m
DDH286 cut 8.6m @ 0.5 g/t gold in the blanket from surface, and a broad interval of highly altered and brecciated basement, which returned 47.0m @ 0.5 g/t gold from 67.5m, including 13.5m @ 0.9 g/t gold from 81m, and including 9.8m @ 1.0 g/t gold from 103.7m
DDH288 intersected 36.0m @ 1.1 g/t gold from surface within the gold-in-oxide blanket, including 4.2m @ 4.0 g/t gold from 16.0m and 2.3m @ 5.0 g/t gold from 31.8m

Alan Carter, Cabral’s President and CEO commented, “The drill program at MG continues to demonstrate that a significant zone of higher grade mineralization occurs within the primary MG gold deposit that forms a distinctive zone. In addition, the current drill program is intersecting excellent widths of good grade material. The terrane is also working in our favour with positive relief improving the strip ration for potential exploitation of the basement saprolite mineralization. Furthermore, the results from the overlying gold-in-oxide blanket continue to demonstrate that a significant zone of higher grade mineralization occurs within the extensive gold-in-oxide blanket.”

MG Diamond-Drill Results

Assay results were returned on six diamond-drill holes (DDH272, DDH273, DDH274, DDH285, DDH286, and DDH288) that were recently completed within the MG gold deposit (Figure 1).

The location of recently completed diamond-drill holes (DDH272, DDH273, DDH274, DDH285, DDH286, and DDH288) are also shown.

Section E553660

Prior to the Cabral’s current drill campaign, only one historic diamond-drill hole, CC104, had ever been drilled on Section E553660, which is located in the east central portion of the MG deposit (Figures 1 and 2). Results from earlier Cabral holes shown on this section, included DDH 208, 209, 210, and 211, and RC238 and 239. Assay results for all of these holes were previously released (see press releases dated April 15, 2021 and December 2, 2021).

The new diamond-drill holes, DDH272 and DDH273, were both drilled on section E553660 (Figures 1 and 2, Table 1) and tested the high-grade main zone within the primary MG gold deposit. Both holes were drilled from the north to the south and were designed to intersect the primary mineralized zone above a deep intercept within the only historic hole drilled on this section. Historic hole, CC104, returned 20.6m @ 1.64 from 269.4m downhole (a vertical depth of 210m), including 2.0m @ 8.7 g/t (Figure 2). The new holes also tested downdip of shallower high-grade intercepts obtained saprolite basement intercept in in DDH209 which returned 21m @ 0.6 g/t gold from 42m downhole, within a 63m @ 0.5 g/t gold intercept extending from surface (Figure 2).

Both the new holes on E553660 intercepted blanket mineralization from surface (Figure 2), confirming the blanket extends 100m further north on this section. DDH 272 returned 44m @ 0.5 g/t gold from surface, while DDH273 cut 18.0m @ 0.95 g/t gold from surface, including 1.0m @ 15.3 g/t gold from 3.0m downhole.

DDH272 and DDH273 also confirmed continuity of the main MG zone of mineralization in the basement between the saprolite basement intercept in DDH209 and the deep historic intercept in CC104 (Figure 2).

DDH272 cut a zone of high-grade zone of mineralization. It returned 17.5m @ 4.0 g/t gold from 102.9m in highly altered and brecciated basement rocks, including 5.5m @ 10.5 g/t gold from 104.1m. The latter 5.5m high-grade intercept was very well mineralized with quartz veining throughout. It contained three separate bonanza intervals, including; 0.5m @ 42.7 g/t gold from 104.1m, 1.0m @ 13.8 g/t gold from 106.6, and 0.5m @ 20.0 g/t gold from 108.7.

DDH273 also encountered highly altered and brecciated basement rocks, returning 7.8m @ 1.2 g/t.

The bonanza intervals encountered in DDH272 appears to occur at the interpreted intersection of the main MG zone and a shallow-dipping structure extending downdip from DDH209, which returned 1.2m @ 2.6 g/t gold (Figure 2). A similar structure was intersected in DDH272, and returned 5.6m @ 2.6 g/t gold from 134.7m. It is also interpreted to be a shallow-dipping structure that intersects the main MG mineralized zone (Figure 2).

It is also worth remembering that there is also a new footwall zone that was discovered on section E553660 in 2021. Drilling 2021 confirmed the presence of a high-grade footwall zone approximately 100m to the south of the main zone on this section (see press release dated April 15, 2021). The 104 zone had only been cut by one historic drill hole (CC104) prior to the current drill program. It intersected 2.0m @ 70.2 g/t gold from 112.5m. Follow-up holes, DDH 208 and DDH 209, were designed to test vertical continuity of that footwall zone, and returned 2.1m @ 29.4 g/t gold, including 0.5m @ 120.6 g/t gold, and 6.1m @1.3 g/t gold, respectively (Figure 2).

Section E552950

Prior to the current program, no holes had been drilled on Section E552950 in the east central portion of the MG deposit (Figure 1 and Figure 3). All drilling on this section was designed to provide strike and vertical continuity through a nearly 100m gap in the drill database between sections E552903 and E552996. Result from RC holes 212, 213 and 214 on the section (Figure 3) were released previously (see press release dated November 24, 2021).

Both of the new diamond-drill holes, DDH 285 and 286, were drilled from the same platform (Figures 1 and 3) and were principally designed to test fresh basement mineralization. Each encountered multiple deep intercepts within the basement, as well as a thin veneer of transported oxide-blanket mineralization extending from surface.

The new drilling confirmed oxide-blanket mineralization extends at least 50m north of previous drilling on Section E552950 (Figure 3). Both DDH285 and DDH 286 intersected blanket mineralization from surface (Figure 3, Table 1), returning 8.0m @ 0.4 g/t gold, and 8.6m @ 0.5 g/t gold, respectively.

The unconformable oxide blanket is fairly thin throughout the section, whilst broad zones of oxidized, soft, saprolite basement mineralization come nearly to surface along the north side of a hill, where intense weathering and oxidation extends to vertical depths of approximately 35m below surface.

Within the basement on Section E552950 the main MG mineralized zone is broader, and drilling confirmed multiple subzones can be traced to more than 130m below surface, while remaining open downdip (Figure 3, Table 1).

DDH285 intersected 31.1m @ 1.3 g/t gold from 105.0m, including 0.5m @ 15.5 g/t gold from 106.0m.

DDH286 returned 47.0m @ 0.5 g/t gold from 67.5m, including 13.5m @ 0.9 g/t gold from 81m, and including 9.8m @ 1.0 g/t gold from 103.7m.

Section E553350

Prior to the current program no holes had been drilled on Section E553350 on the western central side of the MG deposit (Figure 1). All drilling on the section was designed to provide strike and vertical continuity through an 85m gap in the drill database between Sections E553310 and E553395. Result from RC holes 210 and 211 (Figures 1 and 4) were released previously (see press release dated November 24, 2021).

As was the case in Section E552950 discussed above, the unconformable oxidized blanket mineralization on this section is fairly thin, forming the cap on the top and sides of a pronounced hill. Close to surface the basement mineralization is highly weathered and oxidized to saprolite which extends from near the top of the hill, to vertical depths of approximately 50m below surface (Figure 4).

The new diamond hole, DDH 288 (Figures 1 and 4) was designed to test for potential footwall zones within the fresh basement mineralization as well as for basement saprolite and oxide blanket. It encountered a thin horizon of transported oxide-blanket mineralization extending from surface, two thick intercepts of saprolite basement mineralization directly below the oxide blanket, and two weak deep intercepts within the basement. The saprolite intercepts are interpreted to be the up-dip oxidized and highly weathered extension of the subvertical MG basement main zone.

The oxide blanket intercept in DDH288 returned 7.0m @ 0.7 g//t gold from surface (Figure 4). It directly, and unconformably overlies two weathered basement saprolite zones (Figure 4, Table 1). The northern saprolite zone returned 29.0m of 1.2 g/t gold from 7.0m, including; 4.2m @ 4.0 g/t gold from 16m, and 2.3m @ 5.0 g/t gold from 31.8m, while the southern saprolite zone returned 7.0m @ 0.3 g/t gold from 47.0m.

Hole DDH288 also tested for the down-dip extension of basement saprolite encountered in RC0210, which returned 1.0 g/t gold over 19m. The zone appears to be narrower within the basement, running just 1.0m @ 0.8 g/t gold. A second deeper narrow intercept is interpreted to be a shallow-dipping structure extending from the north (Figure 4). It is also possible that both intercepts are shallow-dipping structures that extend down-dip towards the interpreted main zone.

Additional holes were already planned to test the downdip extension of interpreted MG main zone saprolite into basement for this section but have not yet been drilled due to sequencing. At this time no drilling to test the basement main zone has yet been done below the saprolite on this section (Figure 4). These holes should be completed in the next few weeks.

Section E553800

Section E553800 lies towards the eastern side of the MG deposit (Figure 1). Prior to the current drill campaign only one historic diamond-drill hole (CC70) had ever been drilled on this section. It returned an oxide blanket intercept of 32.0m @ 0.28 g/t gold from surface, and two low-grade basement intercepts (13.5m @ 0.4 g/t gold and 10.5m @ 0.61 g/t gold.

Cabral completed several RC holes in 2021, that were released late in the year, including RC159, RC160, RC161 and RC218 (see press release dated October 14, 2021 and November 24, 2021).

All the RC holes were designed to define the gold-in-oxide blanket, although RC161 did confirm the upper basement zone within CC70. RC161 was designed to test for blanket mineralization, but returned 25.0m @ 0.8 g/t from 57.0m to the base of the saprolite. This is probably the weathered up-dip extension of basement mineralization. It continued to cut assay values in the fresh basement, returning 16m @ 1.0 g/t gold below the base of the saprolite in fresh rock, starting at 82m downhole.

Diamond-drill hole DDH274 encountered oxidized blanket from surface, and returned 11.3m @ 0.3 g/t gold from 11.5m downhole. It also returned 8.5m @ 0.8 g/t gold from 146.5m (Table 1) indicating the zone encountered in CC70 and RC161 does continues at depth.


The change in surface topography approaching the western half of the MG deposit may provide additional benefit for the eventual exploitation of the MG mineralization. The hill has significant positive relief that should result in a reduced strip ratio for the initial exploitation of the upper oxidized saprolite main zone and overlying oxide blanket.

As discussed in earlier press releases, this oxidized saprolite and colluvial material should be largely free-digging with lower mining costs. Moreover, preliminary bottle-roll tests, from the company’s ongoing heap-leach test work at KCA labs oxide material was very positive for both oxidized blanket material and basement saprolite mineralization (see press release dated February 24, 2022). Bottle-roll tests of six samples of various grades from saprolite and blanket oxide mineralized types returned 91 to 97% gold recoveries over 48 hours. The best recoveries (97%) were from a basement saprolite basement sample grading 2.3 g/t gold. Heap-leach column testing on a large representative composite sample is ongoing and results should be available in May. This will determine whether Cuiu Cuiu basement saprolite mineralization and oxide blanket are amenable to low-cost, low-capital, heap-leach processing.

Multiple-oriented vein structures contribute significantly to the mineral inventory at many deposits. One of the best examples is Eldorado Gold’s world-class, intrusive-hosted Sigma and Lamaque mines and the nearby Triangle mine in Val D’Or, Quebec (Eldorado Gold press release dated September 5, 2019). Sigma and Lamaque combined to produce 9.5 million ounces of gold from 1935 to 2012. The bonanza grade intercepts at MG have now been traced continuously along strike for at least 235m. They remain open on strike and downdip (see press release dated March 10, 2022). Like Sigma and Lamaque, shallow-dipping structures may form an important control to bonanza grades, and may also provide additional gold resources.

Drilling and Trenching Update

Results are pending on four diamond-drill holes at MG and drilling is continuing.

Results are pending on seven diamond-drill holes at Central and drilling is continuing.

Results are pending on 36 RC holes drilled north of Central which are aimed at further defining the extent of the near surface gold-in-oxide blanket material. The RC rig has now moved to complete infill drilling at the PDM gold-in-oxide blanket with a particular focus on further defining the higher grade core to the blanket.

At the recently discovered mineralized zone in basement granitic rocks at the PDM target located 2.5km NW of Central (see press release dated January 12, 2022), diamond-drilling also has been temporarily suspended as assay results have become too backlogged. Results on twelve diamond-drill holes are currently pending, and need to be interpreted for additional drill hole planning.

Meanwhile, the diamond drill has been redeployed from PDM to Machichie, where an infill and step-out drilling program has just begun and trenching is still in progress.

Results are currently pending on the first two diamond-drill holes drilled in 2022 at the Indio target. Drilling is ongoing.
