Steven Poulton, Chief Executive of Altus, commented:
“We are delighted to report on the outstanding intersection of 1.23 g/t Au over 127m from 21m, including 2.53 g/t Au over 14m from 46m (not true widths) from RC drilling at the Central Prospect at Lakanfla in Western Mali. The current 3,500m drilling programme at Lakanfla forms part of a wider 10,000m programme across the combined Diba & Lakanfla gold project.
“Lakanfla Central is one of at least four key prospects at Lakanfla, with gold mineralisation hosted in a number of sub-vertical breccia zones within a significant porphyritic granite, which has a current strike length of approximately 350m. Lakanfla also hosts a number of widespread zones of intense hard rock artisanal 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. Once completed, the results from the combined drilling programme at Diba & Lakanfla will feed into an updated independent MRE and preliminary economic assessment for the Project. We look forward to updating shareholders as further results are received.”
Lakanfla Licence: Drilling Programme
The drilling programme at the Project is being undertaken by Capital Drilling Limited and comprises up to 10,000m of diamond drilling (“DD”) and RC drilling across Diba & Lakanfla. Following completion of drilling at the Diba Deposit and the Diba NW prospect, approximately 1,550m of RC drilling of a planned 3,500m programme has currently been completed on the Lakanfla licence.
The drilling at Lakanfla has been designed to test a number of targets which could potentially contribute to a maiden MRE for Lakanfla, including:

Diba Deposit Mineral Resource Estimate
The Diba licence forms part of the Diba & Lakanfla project and 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 Deposit 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 |

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 licence
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& Lakanflais 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 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 project 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.
