Drilling Intersects 21.9 g/t over 10.2m at Diba Gold Project, Western Mali

 

(TheNewswire)

 

TheNewswire - 03 November 2021 - Altus Strategies Plc (AIM:ALS) (TSXV:ALTS) (OTC:ALTUF) announces the intersection of high grades from Diamond Drilling (“DD”) at the Company’s 100% owned Diba gold project (“Diba” or the “Project”) in western Mali. Diba hosts a shallow-dipping, near-surface gold deposit (the “Diba Deposit”) and a number of other prospective targets.

 

Highlights:

• - Shallow high-grade DD intersections from Diba gold project in western Mali

  - Intersections from the Diba Deposit (down-the-hole and not true widths) include:

  • - 21.9 grams per tonne (“g/t”) gold (“Au”) over 10.2m from 28m (including 72.2 g/t over 3.0m from 31.0m)

    - 2.0 g/t Au over 25.4m from 43.4m (including 3.2 g/t Au over 12.3m from 56.5m)

    - 1.4 g/t Au over 26.7m from 17.3m (including 4.1 g/t Au over 3.0m from 32.2m)

  - Combined 10,100m DD & Reverse Circulation (“RC”) drilling is underway, designed to:

  • - expand the current Mineral Resource Estimate ("MRE") of the Diba Deposit

    - test the strike and down dip potential of the Diba NW discovery

    - test the extent of the high-grade zone within the Diba Deposit

  - Current programme will be supplemented by up to 2,500m of Air Core (“AC”) drilling

  - Diba is strategically located in a world-famous gold belt that hosts numerous open-pit mines

 

Steven Poulton, Chief Executive of Altus, commented:

“A near-surface intersection of 21.9 g/t over 10.2m represents an outstanding start to the current drilling campaign at the Diba gold project in western Mali. The drilling will comprise up to 10,100m of DD and RC and will be supplemented by up to 2,500m of AC drilling. These programmes are designed to test the potential down-dip and along-strike extensions of the Diba Deposit, as well as increase the resource confidence. At the Diba NW discovery, the drilling will test the strike extent and down dip continuation of the mineralisation. We look forward to updating shareholders on the results of this programme when they are received.”

 

Diba Project: Drilling Programme

The drilling is being undertaken by Capital Drilling Limited and will comprise up to seven DD holes to an average depth of 150m for a total of approximately 1,100m and up to 60 RC drill holes to an average depth of 150m for approximately 9,000m.

 

The DD programme will primarily test the extent of the high-grade zone within the mineralization subject to the current MRE as well as the down-dip extension of the mineralised lenses. In addition, the DD programme will produce orientated core to enable a better structural understanding of the Diba Deposit, as well as density measurements to understand any variations between oxide, transitional and fresh rock domains.

 

The RC programme will primarily target expansion of the known lenses of mineralisation at both the Diba Deposit and Diba NW prospect. The holes will target the along-strike and down-dip extension to previously defined mineralisation. In addition, drill holes will test the potential for further lenses of mineralisation to occur beneath the currently modelled lenses.

Diba Resource: Initial DD Drilling Results

Assay results for the first two DD drill holes have been received from the Diba Deposit (see Table 1), as part of a seven hole programme for a total of 1,100m. The holes are being drilled at -60 degrees inclination and ranged between 69m to 200m in length. The drilling was orientated perpendicular to the interpreted structural orientation of the Diba Deposit.

Diba Project: Location

The 81km2 Diba project (Korali Sud licence) is located in the Kayes region of western Mali, approximately 450km northwest of the capital city of Bamako. The Project sits 5km west of the Company’s Lakanfla gold project, which is under joint venture with ASX-listed Marvel Gold Limited, and approximately 13km south of the multi-million ounce Sadiola gold mine and 35km south of the multi-million ounce Yatela former gold mine, both owned by Allied Gold Corp. Diba is contiguous with the Sadiola permit on its northern and eastern boundaries. Mineralisation hosted on these properties is not necessarily indicative of mineralisation hosted at Diba.

 

Diba Mineral Resource Estimate

Diba hosts a deposit for which an MRE of 217,000 ounces at 1.39 g/t Au (Indicated) and 187,000 ounces at 1.06 g/t Au (Inferred) in both oxide and fresh domains has been made, as set out in Table 2. The MRE was previously reported by the Company on 6 July 2020 (see Altus’ news release titled “Significant Gold Resource at Diba Project, Western Mali”). The Diba Deposit remains open down dip.

 

Table 2: Diba Mineral Resource Estimate

Domain	Indicated			Inferred
	Tonnes (t)	Grade (g/t)	Contained gold (oz)	Tonnes (t)	Grade (g/t)	Contained gold (oz)
Oxide	3,900,000	1.46	183,100	939,000	1.10	33,200
Fresh	934,000	1.12	33,600	4,540,000	1.05	153,300
Total	4,834,000	1.39	217,000	5,479,000	1.06	187,000

Notes:

• - The MRE has an effective date of 6 July 2020.

  - The Mineral Resources in the MRE are classified according to the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) "Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines", dated 29 November 2019, and CIM "Definition Standards for Mineral Resources and Mineral Reserves", dated 10 May 2014.

  - Mineral Resources are reported within a pit shell and are reported to a base-case cut-off grade of 0.5 g/t gold.

  - The quantity and grade of Inferred Resources in the MRE are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Resource category.

  - Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The MRE may be materially affected by environmental, permitting, legal, marketing, or other relevant issues.

  - All tonnages reported are dry metric tonnes. Minor discrepancies may occur due to rounding to appropriate significant figures.

  - Tonnages are rounded to 1,000t and gold to 1,000oz as this is an estimate.

  - Altus is the operator and 100% owner of Diba.

 

Diba Deposit: Geology and Mineralisation

Mineralisation at Diba is sediment-hosted within a series of stacked lenses, typically between 20m and 40m thick. The lenses are shallow-dipping at approximately 30 degrees angled to the east/east-southeast. The Diba Deposit is considered to be controlled by a number of northwest and northeast orientated structures, with gold occurring as fine-grained disseminations in localised high-grade, calcite-quartz veinlets. Alteration at Diba is typically albite-hematite+/-pyrite, although pyrite content is generally very low (<1 %). The weathering profile at the Project is estimated to be up to 70m vertical depth, resulting in extensive oxidation from surface. The oxide gold mineralisation at the Diba Deposit is predominantly found in saprolite within 50m of surface and across a compact 700m x 700m area.

 

QAQC

All drilling samples are collected by the Company following industry best practices with an appropriate number and type of certified reference materials (standards), blanks and duplicates inserted to ensure an effective QAQC regime. RC samples are collected at 1m intervals with representative samples split at the site. Half core DD samples are collected at between 0.5 and 1.5m intervals based on lithological and mineralisation boundaries. Samples from Diba are sent for analysis at SGS SARL (Bamako, Mali) by fire assay technique FAE505. All standard, blanks and duplicates from results discussed in this release have been reviewed and no significant issues with the data have been identified.
