Encouraging Gold Results from Air Core Drilling at Tabakorole Project, Southern Mali


Altus Strategies Plc (AIM: ALS & TSX-V: ALTS), the Africa focused project and royalty generator, announces the results of an Air Core (“AC“) drilling programme to test the potential strike extension of the FT Prospect at the Company’s Tabakorole gold project (“Tabakorole” or the “Project“) located in southern Mali. The programme was completed under the joint venture (“JV“) between Glomin Services Ltd (“Glomin“) and Altus.



·    Encouraging results from 70 hole 2,042m shallow AC drill programme

·    Potential 200m north-westerly strike extension to 2.7km long FT Prospect

·    AC intercepts in highly weathered material include (not true width of intervals):

1.05 g/t Au over 12m from 9m

0.77 g/t Au over 21m from surface

0.95 g/t Au over 15m from surface

·    Excellent correlation between magnetic anomalies and drilled mineralisation

·    FT Prospect is open along strike with further anomalies yet to be systematically tested

·    Historical diamond drilling from FT Prospect of 9.31 g/t Au over 16m, 9.84 g/t Au over 14m and 2.91 g/t Au over 60m (not true width of intervals)

·    Tabakorole hosts a Historical Mineral Resource at the FT Prospect comprised of:

7,880,000 tonnes at 0.94 g/t Au for 240,000 ounces in the Indicated category

10,550,000 tonnes at 1.03 g/t Au for 350,000 ounces in the Inferred category

Based on a 0.5 g/t cut off

A Qualified Person has not undertaken sufficient work to classify the Historical Mineral Resource as a current mineral resource and the Company is not treating the Historical Mineral Resource as a current mineral resource. See “Tabakorole Project: Historical resource” and “Cautionary note regarding historical data”


Steven Poulton, Chief Executive of Altus, commented:

“We are very encouraged by the gold intersections from this shallow 70 hole AC drilling programme at the FT Prospect, which was completed by Glomin under our JV. The results include 1.05g/t Au over 12m from 9m and 0.77 g/t Au over 21m from surface and define a potential 200m north-westerly extension to the known mineralised zone. Perhaps most significantly, the results confirm a very high degree of correlation between gold mineralisation and the structures as interpreted from the recent ground magnetic survey. This programme has extended the potential strike of the 2.7km long FT Prospect and indicates that further extensions seem probable. We look forward to updating shareholders on the next phase of work which we anticipate will be an initial diamond drilling programme.”


Tabakorole Project: AC Drilling Programme

The AC drilling was completed by Capital Drilling Limited and consisted of 70 holes for a total of 2,042m. Drilling was undertaken in areas where elevated historical surface geochemical results were coincident with historic magnetic geophysical anomalies. Drilling was conducted along five NE-SW traverses positioned perpendicular to the regional strike of mineralisation. All holes were drilled at -60 degrees inclination to an average depth of 29m (25m vertical depth). Drill holes were terminated at bit refusal with end of hole depths ranging from 13m to 49m. Nine out of the 70 holes ended in mineralisation.


Results show a strong correlation between the mineralisation reported in AC holes drilled beyond the western margin of the known mineralised shear zone and a magnetic anomaly identified in the recently completed ground geophysical programme. The results indicate the potential to extend the known 2.7km zone of mineralisation, which includes the Historic Mineral Resource at the FT Prospect by up to an additional 600m. Data from the other drill traverses highlight the potential for mineralisation on splays and sub-parallel structures to the main mineralised shear zone.

Sample Methodology and Analysis

The AC drill samples were collected using a spear (PVC pipe) on a 1 metre sample basis and then combined into 3 metre composites for analysis, each of which weighed 1.3kg -5.7kg. Where a 3 metre composite was not possible, the composite interval was adjusted and recorded. A total of 732 samples were composited; blanks, duplicates, and standards were inserted at a frequency of 1:30 as part of a Quality Assurance (QA) procedure.


All samples were prepared by pulverising to 85% passing 75μm and analysed for gold using a 50g fire assay using Atomic Absorption Spectroscopy (AAS). All samples were sent for sample preparation and analysis at the MSALABS facility in Yamoussoukro, Cote d’Ivoire. Quality Control (QC) checks were undertaken on the data received from MSALABS and no significant issues were identified. A secure chain of custody was kept through the process. Of the 732 samples assay results ranged from <0.01ppm Au to 3.07ppm Au, with 85 samples assaying at or above 0.2g/t Au.


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). Mineralization hosted on these properties is not necessarily indicative of mineralization hosted at Tabakorole.


Tabakorole Project: Geology

Tabakorole comprises a 2.7km 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 which is 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 diamond drilling, 31,943m of RC drilling, 6,577m of auger drilling and 60,676m of AC drilling 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.


Following the completion of the Historical Mineral Resource estimate 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 18m from 12m (10FLRC-12A) and 2.53 g/t Au over 24m from 48m (10FLRC-01A).

Tabakorole Project: Historical Mineral Resource

Altus completed a plan of arrangement with Legend Gold Corp. (“Legend”) in February 2018. Legend was at that time the owner of Tabakorole. Since Altus formed a greater portion of the enlarged entity resulting from the plan of arrangement, the Historical Mineral Resource on Tabakorole prepared for Legend is no longer deemed to be a current Mineral Resource. The Historical Mineral Resource estimate is shown in Table 2. The Historical Mineral Resource comprises 240,000 oz Au (7.88 million tonnes at 0.94 g/t) in the Indicated category and 350,000 oz Au (10.55 million tonnes at 1.03 g/t) in the Inferred category. The key assumptions, parameters and methods used to prepare this Historical Mineral Resource were:


·      A block model constructed using the Inverse Distance Squared method

·      Block sizes of 10m X 25m X 5m in the easting, northing and RL directions

·      The block model was estimated in 6 passes at 25m, 50m and 100m ranges

·      Pass 1 & 2 represent spacing of 25m X 50m used to determine the Indicated portion of the resource

·      Pass 2, 3, 4, 5 and 6 were used to estimate the Inferred portion of the resource

·      Three samples minimum were used to estimate any one single block

·      Sample hierarchy:

Bulk screen assays took precedent over regular assays

Diamond drilling assays took precedent over RC drilling assays

AC drilling was not used in the resource estimation

·      Assays were top cut to 10 g/t gold (based on 99.5% on the cumulative frequency curve)

·      Resources were reported at a 0.5 g/t gold cut off


The Historical Mineral Resource was prepared in accordance with NI 43-101 by H. Andrew Daniels, Consulting Geologist, P.Geo in a report entitled “Technical Report on the Mineral Resource Update, June 2007 FT Project Mali, West Africa”, dated July 27, 2007 and filed on SEDAR on July 27, 2007 by North Atlantic Resources Ltd. A Qualified Person has not done sufficient work to classify this Historical Mineral Resource as current Mineral Resources and Altus is not, therefore, treating the Historical Mineral Resource as a current Mineral Resource. However, it remains relevant to the Project and Altus believes it is also reliable. To verify the Historical Mineral Resource so that it can be considered a current mineral resource, a qualified resource consultant would need to review historical drilling data and prepare a mineral resource estimate in accordance with current resource methodology.

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. Several historical drill holes intersected mineralisation off the main trend of the FT Prospect, including 12m at 3.40 g/t Au (06FLRC-01) and 28m at 1.01 g/t Au (06FLRC-04) which represent priority areas for follow up.


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. The next phase of work at Tabakorole is expected to include drilling across new targets and within the area of the Historical Mineral Resource.


Cautionary note regarding historic data

Readers are cautioned that the data on Tabakorole as referred to 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.
