Gold Stock News: Cabral Gold (TSXV: CBR) Drills 20m @ 1.6 g/t and 15m @ 1.8 g/t Gold in Oxidized Material at the MG Gold Deposit, Cuiú Cuiú Gold Project, Brazil
Vancouver, British Columbia - November 29, 2023 (Newsfile Corp.) (Investorideas.com Newswire) Cabral Gold Inc. (TSXV: CBR) (OTC Pink: CBGZF) ("Cabral" or the "Company") is pleased to announce drill results from an additional 12 RC holes from the MG gold deposit, drilled as 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.
- Assay results have been received from an additional 12 RC holes drilled to refine the MG gold-in oxide blanket and basement saprolite wireframe model as a component of an ongoing trial-mining prefeasibility study being conducted by Ausenco
- Highlights include;
- RC375 returned 20m @ 1.6 g/t gold from surface including 9m @ 1.7 g/t gold from surface in the gold-in-oxide blanket and 11m @ 1.6 g/t gold from 9m downhole in basement saprolite
- RC376 returned 15m @ 1.8 g/t gold from 5m depth in basement saprolite including 2m @ 9.2 g/t gold from 11.0m depth
- Drilling is in progress at the Machichie target, located 500m north of MG, where previous drilling suggests the presence of a fourth gold-in-oxide blanket overlying a hard-rock deposit. Previous drilling and trenching traced the primary deposit 900m along strike and the deposit appears to be overlain by a gold-in-oxide blanket and saprolite to a maximum of 30m thickness
- The current drill program is ongoing. A total of 75 RC holes and nine shallow power-auger holes have been completed to date. Assay results are pending on nine power-auger holes drilled at MG, and 31 RC holes drilled at Central and 18 RC holes drilled at Machichie
Alan Carter, Cabral's President and CEO, commented, "These additional drill results from 12 RC holes recently completed at the MG gold deposit demonstrate two important points. Firstly, the results further expand the zone of higher grade +1.5g/t oxide mineralization in the weathered basement saprolite mineralization. Secondly, these results add further support to the fact that the overlying sub-horizontal blanket sediments contain widespread laterally continuous gold mineralization at grades which are remarkably consistent. These additional RC results have increased our confidence regarding the near-surface gold-in-oxide resources in both the blanket sediments and the underlying weathered saprolite material, potentially leading to an expansion of the existing oxide resources at MG."
MG RC Drill Results
The MG gold deposit is one of the two main gold deposits that have been identified to date at Cuiú Cuiú. As with the nearby Central gold deposit, the upper portion of the subvertical MG gold deposit is extensively weathered resulting in a vertical profile of highly weathered basement saprolite extending to 60m depth. These mineralized saprolite zones can be correlated down-dip into primary basement mineralization, although saprolite grades tend to be higher and the distribution of gold mineralization is broader due a reduction in density and gold redistribution during the weathering process. The weathered mineralized basement saprolite is overlain by mud, soil and colluvium material which forms a mineralized blanket. All of the blanket material contains gold that was derived from the chemical and physical weathering the underlying basement saprolite gold mineralization.
Whilst the bulk of the gold resources at MG are contained within the underlying primary (unweathered) basement material (see the NI 43-101 report dated effective July 31, 2022), the overlying oxide material currently contains Indicated Resources of 5.78Mt @ 0.5 g/t for 88,300oz, and Inferred Resources of 1.19Mt @ 0.3 g/t for 12,300oz. A significant amount of higher-grade material (greater than 1.75g/t gold) is contained within these resources and the current drill program at MG is designed to expand these resources within the near-surface saprolite and blanket material. Results from the initial six RC holes completed as part of this program at MG were encouraging and included 27m @ 1.9 g/t gold from surface in RC343 and 28m @ 1.8 g/t gold from surface including 6m @ 7.1 g/t gold in RC342 (see press release dated October 12, 2023).
It is important to note that the most recent resource estimate prepared by SLR Consulting (Canada) Ltd. used a cut-off gold grade for the near surface oxide material of 0.13 g/t gold which represents the value above which material would have reasonable expectation of being economically viable.
The current drill program at MG is being completed as a component of an ongoing trial-mining prefeasibility study being carried out by Ausenco do Brasil Engenharia Ltda. ("Ausenco"). The objectives of the current drill program are to 1) better define and expand the higher-grade portion of the oxide resources within saprolite and blanket material, particularly closer to surface, 2) to improve confidence in the oxide gold resources, and 3) to aid in the mine planning and sequencing as part of the ongoing Ausenco prefeasibility study.
Results from 12 RC holes (RC345, RC349 and holes RC369 to RC378) are discussed herein. All holes were drilled within the overall outline of the oxide resource at MG to a maximum downhole depth of 61m (Figure 1). Several of the holes were originally designed as shallow power-auger holes that were subsequently drilled with the RC rig. Results from all 12 holes are presented in Figure 1 and Table 1 and the more significant results are discussed below.
Drill holes RC376 and RC378 were both drilled on section E553210 in the western part of the MG gold deposit (Figures 1 and 2, Table 1). This was a section where RC205 had previously returned 43.6m @ 1.4 g/t gold from surface in the weathered oxide saprolite and blanket material.
Hole RC376 was drilled to fill a gap in the blanket resource. The hole intersected 15m @ 1.8 g/t gold from 5m depth in saprolite including 2m @ 9.2 g/t gold (Figure 2). This zone of higher-grade mineralization in the saprolite is interpreted to be the same zone intersected in the adjacent drill hole RC205.
RC378 was drilled further to the south in a southerly direction away from the zone of higher grade and returned 12m @ 0.5 g/t gold from surface in blanket sediments. This higher-grade gold mineralization in the overlying blanket sediments appears to be remarkably consistent from section to section.
Holes RC373 and RC375 were both drilled on section E553350 (Figures 1 and 3, Table 1). Both vertical holes were originally planned as power-auger holes but were completed with the RC rig.
RC375 intersected 20m @ 1.6 g/t gold from surface including 9m @ 1.7 g/t gold from surface in blanket sediments and 11m @ 1.6 g/t gold in the underlying weathered basement saprolite from 9m downhole. RC373 intersected 9m @ 0.5 g/t gold from surface in blanket sediments and 4m @ 1.1g/t gold in the underlying saprolite from 21m depth (Figure 3).
The two new holes filled gaps in the blanket mineralization and confirmed higher-grade blanket extends continuously on this section from south of RC211 to north of DDH288 (Figure 3). The existing holes on this section, RC211, RC210, and DDH288 returned intercepts of 8m @ 0.5 g/t, 6m @ 0.6 g/t and 7m @ 0.7 g/t gold from surface, respectively. The blanket intercept in RC375 was significantly higher grade than expected from the current model.
The basement saprolite zone intersected in RC375 (11m @ 1.6 g/t) is interpreted to be the up-dip extension of the same zone intersected in hole DDH288 (returned 29m @ 1.2 g/t gold) (Figure 3). This zone is most likely the same zone of higher-grade mineralization encountered in hole RC342 (28m @ 1.8 g/t gold) drilled on section E553250 100m to the west and the same as that cut in hole RC343 (27m @ 1.9 g/t gold) on section E553210, 140m further west.
RC373 also returned 4m @ 1.1g/t gold in the underlying saprolite from 21m depth. The hole ended in +1g/t gold mineralization indicating that the mineralized zone remains open at depth.
RC369 was drilled on section E553500 (Figures 1 and 4, Table 1) and intersected 26m @ 0.5 g/t gold from surface in blanket sediments. This is consistent with previous drilling on this section and confirms the remarkable lateral sub-horizontal continuity of grade in the near surface blanket sediments.
Drilling is in progress at the Machichie target, located 500m north of MG, where previous drilling suggests the presence of a fourth gold-in-oxide blanket overlying a hard-rock deposit. Previous drilling and trenching traced the primary deposit 900m along strike and the deposit appears to be overlain by a gold-in-oxide blanket and saprolite to a maximum of 30m thickness.
The current drill program is ongoing. A total of 75 RC holes and nine shallower power-auger holes have been completed to date. Assay results are pending on nine power-auger holes drilled at MG, and 31 RC holes drilled at Central and 18 RC holes drilled at Machichie.
