Drilling Intersects High Grade Gold at Tabakorole in Southern Mali

Monday, 17 August 2020 07:00 AM

Altus Strategies Plc

DIDCOT, UK / ACCESSWIRE / August 17, 2020 / Altus Strategies Plc (AIM:ALS) (TSX-V:ALTS) (‘'Altus'' or the ‘'Company''), announces high grade drilling results from the FT Prospect at the Company's Tabakorole gold project ("Tabakorole" or the "Project") in southern Mali. The drilling was completed by Graphex Mining Limited (ASX:GPX) ("Graphex") under the joint venture ("JV") with Altus.

Highlights:

  • Results from an eight-hole (1,544m) diamond drilling programme at Tabakorole
  • Intersections include 4.7 g/t Au over 14.0m and 1.2 g/t over 31.0m (not true widths)
  • Potential 600m long north-west extension confirmed with 1.2 g/t Au over 12m
  • Project remains open along strike and down dip
  • Updated mineral resource estimate on Tabakorole is now being prepared
  • Graphex is earning an initial 33% interest in the Project under the JV
  • Altus holds a Net Smelter Return gold royalty on Tabakorole

Steven Poulton, Chief Executive of Altus, commented:

"We are encouraged to report the high grades and broad widths of gold mineralisation intersected from the recent drilling programme at Tabakorole. The programme was financed and completed by our ASX-listed JV partner Graphex Mining, which is earning an initial 33% interest in the Project. The intersection of 4.7 g/t gold over 14m, within a wider envelope of 38m averaging 2.1 g/t gold is excellent. The results have also extended a high-grade plunge that was not previously modelled in the 2007 historical mineral resource estimate. An updated independent mineral resource estimate is now being prepared, which will include results from the 11,736m of reverse circulation and 1,936m of diamond drilling that have occurred at Tabakorole since 2007."

"The potential of the 600m long north-west extension has also been confirmed, with an intersection of 1.2 g/t gold over 12m from the one diamond hole drilled in this area, which is in the vicinity of the recently reported shallow aircore drill intersection of 6.2 g/t gold over 6m from 14m depth."

"We look forward to updating shareholders on the progress at Tabakorole and specifically with news on the updated mineral resource estimate when available."

Drilling programme

The drilling was undertaken by Capital Drilling Limited and consisted of eight diamond drill holes for a total of 1,544m. The drill results are summarised in Table 1 below. The holes were drilled between -52 and -60 degrees inclination, perpendicular to the strike of the FT Prospect and ranged between 62.5m to 293.0m in length.

The programme was designed to:

  • Test high-grade plunge extensions;
  • Drill untested gaps in the deposit;
  • Drill a single hole into the north-west strike extension; and
  • Provide QAQC support for the deposit model.

Testing high-grade plunge extensions

One of the key aims of the programme was to target the interpreted high-grade plunge extension at the south-east end of the FT Prospect. Three holes were positioned to following-up on historical intersections of 2.5 g/t Au over 24m (hole 10FLRC-01A) and 2.6 g/t Au over 24m (hole 10FLRC-06A). Drilling successfully confirmed and expanded the high-grade plunge extension and returned the following results:

  • 20TBK-DD_004: 2.1 g/t Au over 38m from 145m, including 4.7 g/t Au over 14m from 145m
  • 20TBK-DD_001: 1.2 g/t Au over 31m from 191m, including 2.1 g/t Au over 6m and 4.0 g/t Au over 4m
  • 20TBK-DD_003: 1.0 g/t Au over 35m from 170m, including 1.3 g/t Au over 20m from 173m

The mineralisation remains fully open to the south-east and represents a high priority target for follow up drill testing.

Drilling untested gaps

Despite the amount of historical drilling, numerous untested gaps within the FT Prospect exist. Three holes were drilled to infill some of these areas and provide greater continuity for the forthcoming updated mineral resource estimate:

  • 20TBK-DD_005: target an untested gap and intersected 1.0 g/t Au over 47.0m to a maximum depth of 85.0m from surface. This area of the FT Prospect did not previously contribute to the historical resource estimate due to the low drill density. This hole demonstrates the continuity of the resource and is higher grade than the material immediately down dip. Hole 20TBK-DD-005 will be included in the new mineral resource estimate.
  • 20TBK-DD_006: was drilled up-dip of historical hole 05FLDDH-14 (which intersected 11.2 g/t Au over 9m). This hole intersected 0.5 g/t Au over 25m.
  • 20TBK-DD_002: was drilled on the same section as 20TBK-DD_006 and intersected 1.2 g/t Au over 27m.

North-west extension

The north-west extension represents a significant opportunity to grow the FT Prospect.

  • 20TBK-DD_008 tested the north-western extension between previously drilled aircore holes. It will aid in interpreting the orientation of the orebody in this area. This hole successfully intersected both interpreted lodes returning 1.2 g/t Au over 12m from 41m and 0.8 g/t Au over 8m from 111m.

Results from this single diamond hole reinforce the potential along this part of the prospect, especially when viewed alongside the recent aircore drilling, which encountered a 28m wide zone with an average grade of 2.7 g/t Au and a best intercept of 6.2 g/t Au over 6m (see Company announcement of 06 August 2020).

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 2.

In 2010, a total of 58 RC holes (5,492m) were completed within and along strike of the FT Prospect. 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).

Cautionary note regarding historic data

Readers are cautioned that the historical data on Tabakorole in this written disclosure 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. 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. 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.
