Drilling Underway at Tabakorole Gold JV Project, Southern Mali

DIDCOT, May 26, 2020 - Altus Strategies Plc (AIM:ALS)(TSXV:ALTS) (‘'Altus'' or the ‘'Company''), the Africa focused project and royalty generator, announces the commencement of a 1,600m Diamond Drilling ("DD") programme at the Company's Tabakorole gold project ("Tabakorole" or the "Project") located in southern Mali. The programme is focused on the 2.7 km long FT Prospect and is being managed and financed by Glomin Services Ltd ("Glomin") under the first phase of the joint venture ("JV") between Glomin and Altus.

Highlights:

• JV financed drilling programme underway at Tabakorole gold project in southern Mali
• Focus on 2.7 km long FT Prospect and testing a potential 200m long extension
• Programme targeting high-grade trends from historic drilling including (not true widths):
  • 6.05 g/t Au over 18m
  • 9.31 g/t Au over 16m
  • 2.75 g/t Au over 66m
• Robust health and safety procedures adopted at the project in response to COVID-19

Steven Poulton, Chief Executive of Altus, commented:

"We are pleased to announce the commencement of a 1,600m diamond drilling programme at our Tabakorole gold project in southern Mali. The programme will be targeting modelled high-grade trends defined by historical drilling at the 2.7 km long FT Prospect and also test a potential 200m long northwest extension, as defined by recent ground magnetics and aircore drilling. The drilling is being managed and financed by Glomin under the first phase of the JV earn-in agreement. In response to the COVID-19 pandemic, Glomin has established enhanced health and safety procedures at the project. We look forward to updating shareholders on the results from the drilling in due course."

Tabakorole Project: Diamond Drilling Programme

The planned 1,600m DD programme will comprise eight holes, each inclined between -52 to -59 degrees and drilled perpendicular to the regional strike of mineralisation. The drilling will test the potential for mineralisation in the oxide and fresh portions of the FT Prospect, with holes ranging between 120m to 290m depth (69m to 166m vertical depth). Capital Drilling Ltd has been contracted to undertake the programme.

The majority of the planned holes are designed to test potential high-grade plunges and dip extensions of historical drilling, predominantly in the southeast of the FT Prospect where historic drilling has encountered high grades including (not true width of intervals):

• 3.4 g/t Au over 12m from 126m in hole 06FLRC-01
• 2.9 g/t Au over 60m from 14m in hole 05FLRC-11
• 2.9 g/t Au over 26m from 72m in hole 05TKRC-18
• 1.5 g/t Au over 34m from 93m in hole 05FLRC-41
• 1.6 g/t Au over 28m from 18m in hole 10FLRC-05
• Up dip from 11.2 g/t Au over 9m from 307m in hole 05FLDDH-14
• Down dip from 3.8 g/t Au over 16m from 26m in hole 10FLRC-08
• One hole will target the northwest extension to the FT Prospect, where recent AC results included 1.1 g/t Au over 12.0m from 9.0m and 0.8 g/t Au over 21.0m from surface

Tabakorole Project: Location

The 100 km² Tabakorole gold project is located in southern Mali, approximately 280 km south of the capital city of Bamako. The Project sits on the Massagui Belt which hosts the Morila gold mine (operated by Barrick NYSE:GOLD, TSX:ABX), located approximately 100 km to the north. The Project is 125 km southeast of the Yanfolila gold mine (operated by Hummingbird AIM:HUM) and 100 km east of the Kalana gold project (operated by Endeavour Mining TSX:EDV). Mineralisation hosted on these properties is not necessarily indicative of mineralisation hosted at Tabakorole.

Tabakorole Project: Geology

Tabakorole comprises a 2.7 km long shear zone which is up to 200m wide, hosted in the Archaean and Birimian aged Bougouni Basin of the Man Shield of southern Mali. The geology is dominated by clastic sediments, cut by northwest trending deformation zones which host gold mineralisation. At least two, possibly three, Eburnean deformation events are believed to have affected the geology of Tabakorole. The Project hosts the FT prospect comprised of mylonites, sheared diorite, gabbro, mafic dykes and late stage felsic dykes, within a folded and deformed metasedimentary package of meta-siltstone, meta-wacke and meta-sandstone. Mineralisation is locally most favourably associated where structures cut gabbro and along lithological contacts with gabbro.

Tabakorole Project: Historical exploration

The Project was discovered by a regional soil sampling programme completed on a 500m x 100m grid by BHP in the early 1990s. Since 2003, a total of 28,912m of DD, 31,943m of RC, 6,577m of auger drilling and 62,718m of AC have been completed, in addition to 1,400 line km of airborne geophysics. A selection of drill intersects from Tabakorole is shown in Table 1.

In 2007, 58 RC holes (5,492m) were completed within and along strike of the FT Prospect in 2010. Results included 6.05 g/t Au over 18.0m from 12.0m (10FLRC-12A) and 2.53 g/t Au over 24.0m from 48.0m (10FLRC-01A) (not true widths).

Notes:

1. Intersections based on 0.5g/t Au cut off and ≤ 2m internal waste
2. Intersections are down-the-hole and do not represent true widths of mineralisation
3. No grade capping has been applied

Tabakorole Project: New targets defined from historical data

The Company has completed a comprehensive review of the historical exploration data on the Project. A number of priority drill targets have been defined both within the main NW-SE trend of the existing FT Prospect as well as potential extensions on strike. Six hundred metres to the south of and parallel to the FT Prospect, a new prospect which is approximately 2.5 km long has been defined from historical airborne magnetic data. Elsewhere on the Tabakorole licence a number of priority targets for follow up trenching and auger drilling have been defined from the recent and historical geophysical programmes as well as historic surface geochemical data.

COVID-19 Procedures

In response to the COVID-19 pandemic, enhanced health and safety procedures have been implemented at the Tabakorole project. Additional measures include (but are not limited to):

• Mandatory and regular hand washing with enhanced facilities for staff and contractors
• No non-essential travel with all movements in and out of site requiring approval
• Minimum 2m distance between employees where possible and handshaking not permitted
• Health monitoring and self-isolation measures
• Establishment of a quarantine facility and intense cleaning procedures

Cautionary note regarding historic data

Readers are cautioned that the data on Tabakorole in this written disclosure is historical exploration data that has not been verified by a Qualified Person. Not all historical samples are available and Altus does not have complete information on the quality assurance or quality control measures taken in connection with the exploration results, or other exploration or testing details regarding these results. There has been insufficient exploration to define a current mineral resource and the Company cautions that there is a risk further exploration will not result in the delineation of a current mineral resource. Intersections cited in this news release do not represent true widths of the mineralised intervals. The historical drilling was predominantly angled at -60 and -55 degrees and intersected steeply dipping mineralisation. True width determinations are estimated to be 50-57% of the cited intersection lengths.

The technical disclosure in this regulatory announcement has been read and approved by Steven Poulton, Chief Executive of Altus. A graduate of the University of Southampton in Geology (Hons), he also holds a Master's degree from the Camborne School of Mines (Exeter University) in Mining Geology.
