Investigating Potential to Commence Small Oxide Mining Operations

调查开展小型氧化物开采业务的可能性

Toronto, Ontario--(Newsfile Corp. - May 3, 2023) - Compass Gold Corp. (TSXV: CVB) (Compass or the Company) is pleased to provide an update on additional assay data on recently completed deep reverse circulation drilling, and surface channel and grab sampling at the Tarabala prospect, located on the Company's Sikasso Property in Southern Mali (Figure 1).

安大略省多伦多-(Newsfile Corp.-2023年5月3日)-指南针黄金公司(多伦多证券交易所代码:CVB)(指南针(该公司)很高兴提供关于最近完成的深层反循环钻探以及位于公司位于马里南部的Sikasso地产的Tarabala勘探区块的地面渠道和抓取采样的更多化验数据的最新情况(图1)。

Highlights

亮点

  • Coarse-grained "nuggety" gold is confirmed at Tarabala, and likely present at other locations along the Tarabala Trend

  • Best interval with increased gold: 19 m at 1.68 g/t Au (from 170 m), compared to 0.84 g/t Au from cyanide extraction (an increase of 200%)

  • Nuggety gold shown to occur in fresh rock at depth, and not solely in the near-surface weathered laterite

  • Metallic screen fire and cyanide extraction assay results are in good overall agreement

  • Reconfirms that mineralization remains open at depth and along strike

  • The Company is considering the development of a small mining operation on high-grade near-surface gold mineralization to generate a near-term revenue stream

  • 粗粒“块状”黄金在塔拉巴拉得到证实,并可能出现在塔拉巴拉趋势的其他地方。

  • 黄金增加的最佳间隔:19米,黄金1.68克/吨(170米),而氰化提金0.84克/吨(增加200%)

  • 有证据表明,块状金赋存于深部的新鲜岩石中,而不仅仅是近地表的风化红土。

  • 金属屏蔽火和氰化物萃取分析的结果总体上是一致的

  • 再次确认矿化在深度和走向上保持开放状态

  • 该公司正在考虑开发一项关于高品位近地表金矿化的小型采矿业务,以产生短期收入来源

Compass CEO, Larry Phillips, said, "While our primary goal has always been to discover a large, open-pittable gold deposit in Mali, our technical team has successfully identified several exciting wide, near-surface mineralized trends typically containing gold grades of about 1 g/t Au. These are outstanding results, as many of the largest mines in West Africa are producing gold at grades of between 0.75 and 1.1 g/t Au. In fact, the drilling and assaying we have recently completed on our Tarabala prospect have clearly demonstrated the potential to develop one or more small, near-surface mines which could generate ongoing revenue to fund the exploration work required to develop a far larger, open-pittable gold resource."

Compass首席执行官拉里·菲利普斯,说,虽然我们的主要目标一直是在马里发现一个大型的可露天开采的金矿,但我们的技术团队已经成功地发现了几个令人兴奋的宽广的近地表矿化趋势,通常含有约1 g/t Au的黄金品位。这些都是突出的结果,因为西非许多最大的金矿正在生产品位在0.75克/吨到1.1克/吨之间的黄金。事实上,我们最近完成的塔拉巴拉探矿的钻探和分析清楚地表明了开发一个或多个小型近地表矿山的潜力,这些矿山可以产生持续的收入,为开发规模大得多的露天金矿资源所需的勘探工作提供资金。“

Dr. Madani Diallo, Director and Country Manager, added, "During our ongoing quest to uncover an open-pitiable, high-grade gold deposit, we have completed 20,000 m of drilling and intercepted several large sections of lower-grade mineralization along the 20 km long Massala-Tarabala-Moribala trends. We are excited about working to define open pittable low-grade gold resources that are easy to mine and process with an appropriate plant as done elsewhere in the region, such as AngloGold Ashanti's Siguri mine in Guinea, which has been mining gold from a series of 18 pits at average grades of less than 1 g/t Au since 2008. Such operations are particularly attractive at a time when the gold price is approaching US$2,000/oz."

董事和国家经理Madani Diallo博士他补充说:“在我们不断探索发现一个露天的可怜的高品位金矿床的过程中,我们已经完成了20,000米的钻探,并沿着20公里长的Massala-Tarabala-Moribala走向截获了几个大的低品位矿化区段。我们很高兴能像该地区其他地区那样,利用合适的工厂,确定易于开采和加工的露天可开采低品位金矿资源,例如几内亚的盎格鲁黄金阿散蒂Siguri矿,该矿自2008年以来一直在一系列18个矿坑开采黄金,平均品位低于1克/吨金。在金价逼近每盎司2,000美元之际,这类业务尤其具有吸引力。

Dr. Sandy Archibald, PGeo, Technical Director, added, "Our latest results are extremely encouraging and continue to validate our view that, due to the presence of nuggety gold along our mineralized trends, conventional fire assaying has very likely under-reported gold grades within the main target zones like Tarabala. We look forward to further testing the open structure along strike and down dip."

桑迪·阿奇博尔德博士,PGeo,技术董事他补充道:“我们的最新结果非常鼓舞人心,并继续验证我们的观点,即由于我们的矿化趋势沿线存在块状金矿,传统的火试金法很可能在塔拉巴拉等主要目标区内漏报了金品位。我们期待着进一步测试沿走向和向下倾斜的开放结构。”

Next Steps

接下来的步骤

Compass plans to collect and test a series of large (10-15 kg) channel samples from existing surface workings at the Tarabala prospect to test gold recoveries from the near-surface zone. If results are positive, additional channel samples will be collected at prospects along the Tarabala and Moribala trends.

Compass计划从塔拉巴拉探矿的现有地表工作场所收集和测试一系列大型(10-15公斤)河道样本,以测试从近地表地带回收黄金的情况。如果结果是肯定的,将在塔拉巴拉和莫里巴拉趋势沿线的Prospects收集更多的渠道样本。

The Company is also finalizing plans for a deep trenching and pitting program at the main Tarabala prospect to develop the optimal scenario for mining gold from the near-surface laterite. This program will involve the excavation of five 5-m deep, and 100-m long trenches, and the collection and analysis of the recovered 1 m channel samples. In addition, a series of 5 m deep pits will be dug every 20 m between the trenches and the channels sampled and analysed for gold.

该公司还在敲定在塔拉巴拉主要探矿地进行深挖和挖坑计划的计划,以开发从近地表红土中开采黄金的最佳方案。这项计划将涉及挖掘5条5米深、100米长的战壕,并收集和分析回收的1米航道样本。此外,将在每隔20米挖掘一系列5米深的坑,这些坑将在沟渠和渠道之间进行取样和分析以寻找黄金。

Recent Tarabala Drilling Results

塔拉巴拉最近的钻探结果

Six RC drill holes (1,036 m) were drilled in early March at the Tarabala prospect to test the down-dip extension of mineralization previously identified by near-surface drilling (Figure 1). The 1-m sample intervals were analysed for gold using cyanide-leach (LeachWELL) analysis and the results reported in a Compass press release on April 18, 2023. The analysis identified a wide zone of gold mineralization (greater than 10 m) in five of the six holes (Table 1). The widest intercept was 19 m @ 0.84 g/t Au (from 170 m, SARC022), and the highest grade was 13 m @ 3.30 g/t Au (from 84 m, SARC019), which included a 1 m @ 18.90 g/t Au (from 86 m). The presence of high-grade gold samples in fresh rock is indicative of coarse-grained ("nuggety") gold. To investigate the presence of nuggety gold, duplicate sample intervals were analysed using the Metallic Screen Fire Assay (MSFA) technique, which uses different crushed and sieved fractions to determine the presence of coarse-grained gold. The results of the Metallic Screens are tabulated in Table 1.

3月初在Tarabala勘探区块钻了6个RC钻孔(1,036米),以测试之前通过近地表钻探确定的矿化向下延伸(图1)。使用氰化物浸出(LeachWELL)分析方法对1-m采样间隔中的金进行了分析,并在2023年4月18日的Compass新闻稿中报告了结果。分析发现,六个洞中有五个有宽阔的金矿化带(大于10米)(表1)。截获范围最广的是19米@0.84g/吨Au(距离170米,SARC022),最高等级为13米@3.30克/吨Au(从84米,SARC019),其中包括1米@18.90克/吨的金(从86米)。新鲜岩石中高品位金样的存在表明了粗粒(“块状”)金的存在。为了调查块状金的存在,使用金属筛火分析(MSFA)技术对重复采样间隔进行了分析,该技术使用不同的粉碎和筛分来确定粗粒金的存在。金属筛的结果如表1所示。

The greatest increase in grade was present in SARC018 where 10 m @ 0.39 g/t Au (cyanide) became 10 m @ 1.34 g/t Au (MSFA), a 344% increase. The widest drilled intercept was encountered in SARC022, where 19 m @ 0.84 g/t Au (from 170 m, SARC022), (cyanide) increased to 19 m @ 1.68 g/t Au (from 170 m, SARC022), (MSFA), which doubles the grade of the interval. Increases were also seen in intervals in SARC017 and part of a narrower interval in SARC022. The largest decrease was present in SARC019, where 13 m @ 3.30 g/t Au (from 84 m), was reduced in grade to 13 m @ 1.14 g/t Au (from 170 m, SARC022). This reduction is expected since the nature of coarse gold means the variability (heterogeneity) is likely to be high even in duplicate samples from the same interval. What is promising about this sample interval is that the MSFA showed gold was still above 1 g/t Au in the bedrock.

成绩增幅最大的是SARC018,10米@0.39克/吨Au(氰化物)变成了10米@1.34克/吨Au(MSFA),增长344%。最宽的钻井拦截是在SARC022遇到的,在那里19米@0.84g/吨Au(从170米,SARC022),(氰化物)增加到19米@1.68克/吨Au(从170米,SARC022),(MSFA),这使区间的等级翻了一番。SARC017和SARC022的区间也出现了间歇性上升。降幅最大的是SARC019,13米@3.30克/吨Au(从84米),等级降至13米@1.14克/吨Au(距离170米,SARC022)。这一下降是意料之中的,因为粗金的性质意味着即使在相同区间的重复样品中,变异性(异质性)也可能很高。关于这个采样间隔,有希望的是,MSFA显示基岩中的金仍然在1g/t Au以上。

Important takeaways from the work are: coarse gold is present in bedrock samples, grades are generally higher in the MSFA samples, and grades in the widest intervals are greater than 1 g/t Au.

这项工作的重要结论是:基岩样品中存在粗金,MSFA样品中的品位通常较高,最宽区间的品位大于1g/t Au。

Tarabala Channel Sampling Results

塔拉巴拉海峡抽样结果

A total of twenty-two, 5 kg surface samples (12 channel and 10 quartz vein grab) were collected from four areas over a strike length of 600 m of artisanal workings at Tarabala in March 2023. The samples were analysed for gold using cyanide leach extraction ("cyanide") and metallic screen fire assaying (MSFA). The aim of the sampling was to compare assaying techniques for surface samples, and determine if the samples displayed coarse gold. The channel samples collected from artisanal workings on the surface projection of mineralization from SARC017-19 contained 8 m @ 1.72 g/t Au (cyanide leach) and 8 m @ 1.08 g/t Au (MSFA). Due to safety considerations, it was not possible to sample the complete 12 m mineralized zone. The highest-grade sample analysed by cyanide leaching contained 9.83 g/t Au, whereas the same sample analysed by MSFA contained 3.71 g/t Au. The average grade of the zone, excluding the high-grade interval, was 7 m @ 0.56 g/t Au (cyanide) and 7 m @ 0.71 g/t Au (MSFA).

2023年3月,在塔拉巴拉600米的人工工作面上,从四个区域采集了22个5公斤的地表样本(12个通道和10个石英脉抓斗)。用氰化物浸提法(“氰化物”)和金属屏火法(MSFA)分析了样品中的金。采样的目的是比较表面样品的分析技术,并确定样品是否显示为粗金。从SARC017-19矿化地表投影上采集的手工开采的沟槽样品包含8米@1.72克/吨Au(氰化物浸出)和8米@1.08克/吨Au(MSFA)。出于安全考虑,无法对完整的12米矿化带进行取样。氰化浸出分析的最高品位Au含量为9.83g/t,而MSFA分析的同一样品Au含量为3.71g/t。除高品位区段外,该带的平均品位为7米@0.56克/吨金(氰化物)和7米@0.71克/吨金(MSFA)。

Four samples collected 80 m north of the channel samples on the main north-south veins system averaged 0.58 g/t Au (cyanide) and 0.50 g/ Au (MSFA). Two samples collected to test east-west cross-cutting veins contained 0.10 g/t Au (cyanide) and 0.09 g/t Au (MSFA).

在航道以北80m处采集的4个样品中,南北主脉系的Au平均为0.58g/t(氰化物)和0.50g/Au(MSFA)。两个用于测试东西横贯矿脉的样品分别含有0.10g/t Au(氰化物)和0.09g/t Au(MSFA)。

Two samples of mineralization sampled 450 m south of the channel sample location averaged 0.78 g/t Au (cyanide) and 0.56 g/t Au (MSFA). The final samples collected were an additional 50 m to the south, with the highest grade recorded being 5.38 g/t Au (cyanide) and 7.35 g/t Au (MSFA). The sampling locations are close to where an air core drill hole intercepted 5 m @ 2.86 g/t Au (from 8 m, SAAC083) in December 2020.

在航道采样位置以南450m处采集的两个矿化样品平均为0.78g/t金(氰化物)和0.56g/t金(MSFA)。最终采集的样品是向南另外50米处,记录到的最高品位为5.38克/吨金(氰化物)和7.35克/吨金(MSFA)。采样地点接近2020年12月一个空气岩心钻孔截获5m@2.86g/t Au(SAAC083的8m)的位置。

Statistical analysis of the surface and drilling cyanide versus MSFA assay results showed that coarse gold was slightly more abundant in surficial samples (one in four, or 25%), compared to one-in-six (17%) of the bedrock samples.

对地表和钻探氰化物与MSFA分析结果的统计分析表明,表面样品中的粗金含量略高(四分之一,或25%),而基岩样品中的粗金含量为六分之一(17%)。

Technical Details
