Further Significant Intercepts from Diba & Lakanfla Gold Project in Western Mali



x-Altus Strategies Plc

 

17 March 2022 – TheNewswire - Altus Strategies Plc (AIM:ALS), (TSXV:ALTS), (OTC:ALTUF) announces further significant gold intersections from reverse circulation (“RC”) drilling at the Company’s 100% owned, 105 square kilometre (“km2”) Diba & Lakanfla gold project (“Diba & Lakanfla” or the “Project”) in western Mali. The Lakanfla licence is located approximately 5 kilometres (“km”) east of the Company’s Diba licence. Both licences host numerous gold prospects, including a shallow-dipping, near-surface gold deposit (the “Diba Deposit”).

 

Highlights:

  • RC drilling completed at 100% owned Diba Lakanfla in western Mali 

  • Latest intersections from the Lakanfla Central prospect include (not true widths): 

    • 0.90 grams per tonne (g/t”) Au over 66 metres (“”) from 41m 

    • 1.32 g/t Au over 26m from 85m 

    • 2.21 g/t Au over 12m from 137m 

    • 4.37 g/t Au over 6m from 32m 

  • Latest intersections from the Diba NW prospect include (not true widths): 

    • 1.81 g/t Au over 10m from 256m 

    • 0.60 g/t Au over 23m from 154m 

  • Programme designed to generate an updated Project Mineral Resource Estimate (MRE”) 

  • MRE to be integrated into an updated Preliminary Economic Assessment (PEA”) 

  • trategically located in a world-famous gold belt that hosts numerous open-pit mines 

 

Steven Poulton, Chief Executive of Altus, commented:

“We are pleased to report on the further encouraging drilling intersections from the Diba & Lakanfla gold project in western Mali. RC results include 1.32 g/t Au over 26m from 85m and 0.90 g/t Au over 66m from 41m (not true widths) from the Lakanfla Central prospect. These results extend the mineralised strike of Lakanfla Central by approximately 200m to approximately 750m, with mineralisation remaining open to the northeast and at depth. The latest results confirm the presence of a broad gold mineralised package at Lakanfla Central, from which we recently reported an intersection of 1.23 g/t Au over 127m from 21m (not true width).

 

“Lakanfla Central is hosted within a large porphyritic granite and is one of at least four priority prospects at Lakanfla, where gold mineralisation is often associated with sub-vertical and brecciated structures. Lakanfla hosts a number of zones of intense hard rock artisanal gold workings. Historical results from drilling at the Lakanfla licence include 5.10 g/t Au over 26m, 4.31 g/t over 18m and 1.02 g/t Au over 60m (not true widths).

 

"Lakanfla is located approximately 5km east of the Diba licence, which hosts the Diba Deposit and the Diba NW prospects. The results from the now completed drilling programme at Diba & Lakanfla will feed into an updated independent MRE and PEA for the Project. We look forward to updating shareholders on the results of these studies in due course.”

 

Diba & Lakanfla Project: Drilling Programme

The 11,832m drilling programme at the Project has been completed by Capital Drilling Limited and comprised 1,359m of diamond drilling (“DD”), 1,433m of air core (“AC”) and 9,040m of RC drilling.

 

The most recent and final phase of drilling at Lakanfla comprised 3,848m of RC, testing a number of targets which could potentially contribute to a maiden MRE including:

 

Lakanfla Central Prospect

  • Twenty holes for a total of 3,283m were drilled 

  • The prospect comprises a series of mineralised breccias within an altered granodiorite host with surrounding carbonate metasediments 

  • Drilling targeted the prospect at depth and tested potential on strike extensions 

 

Zone 3 Prospect

  • Three holes for a total of 390m were drilled 

  • The prospect hosts mineralised breccia at surface and artisanal workings 

  • Drilling tested the strike potential of the prospect 

 

Zone 4 Prospect

  • Two holes for a total of 175m were drilled in addition to a programme of trenching  

  • The prospect hosts a number of high-grade gold in soil anomalies 

  • Drilling was undertaken to test strike potential 

 

Diba & Lakanfla Project: Drilling Results

All assay results have now been received from the current programme at Diba & Lakanfla (see Table 1). The holes were drilled at between -50 to -70 degrees inclination and range between approximately 75m to 315m in length. The drilling was orientated perpendicular to the interpreted structural orientation at Diba & Lakanfla.

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. Altus is not currently aware of any such 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 in the totals as this is an estimate 

  • Altus is the operator and 100% owner of the Diba and Lakanfla licences 

 

Diba & Lakanfla: Location

The 81km2 Diba licence (Korali Sud) and the 24km2 Lakanfla licence are located 5km apart in the Kayes region of western Mali, approximately 450km northwest of the capital city of Bamako. Diba & Lakanfla is located adjacent to the multi-million ounce Sadiola gold mine licence and 35km south of the multi-million ounce Yatela former gold mine, both acquired by Allied Gold Corporation from the previous operators AngloGold Ashanti (JSE: ANG, NYSE: AU and ASX: AGG) and IAMGOLD Corporation (TSX: IMG and NYSE: IAG). Mineralisation hosted on these mines is not necessarily indicative of mineralisation hosted at Diba & Lakanfla.

 

Diba & Lakanfla: Geology & Mineralisation

Diba Licence

Mineralisation at the Diba Deposit on the Diba licence is sediment-hosted within a series of stacked quartz 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 the Diba Deposit is typically albite-hematite+/-pyrite, although pyrite content is generally very low (<1%). The weathering profile at the Diba Deposit 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.

 

Lakanfla Licence

The Lakanfla licence hosts a significant number of active and historic artisanal gold workings coincident with significant geochemical and gravity anomalies. The workings surround the Kantela granodiorite intrusion and cover an area of approximately 900m x 500m. The gold mineralisation at Lakanfla is typically hosted within breccia zones which cut the granodiorite and surrounding carbonate metasediments. Drilling by the Company has intersected 1.23 g/t Au over 127m (not true widths) at the Lakanfla Central prospect, while historic intersections by previous operators include 9.78 g/t Au over 12m and 5.20 g/t Au over 16m (not true widths) as well as having intersected voids and unconsolidated sand from 165-171m depth. The Company has not verified the historic drilling data at the Lakanfla licence.

 

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 Quality Assurance Quality Control “QAQC” regime. RC samples are collected at 1m intervals with representative samples split at the site. Half core DD samples are collected at between 0.5m and 1.5m intervals based on lithological and mineralisation boundaries. Samples from the Project 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.
