Drilling Underway at Lakanfla Gold Project,
Altus Strategies Plc (AIM: ALS, TSX-V: ALTS, OTCQX: ALTUF) announces the commencement of a 3,800m drilling programme at its Lakanfla gold project ("Lakanfla" or the "Project") located in western
· JV-financed 3,800m drill programme underway at the Lakanfla project in western
· Targeting a karst-style target analogous to Yatela and the FE3 / FE4 deposits at Sadiola
· Lakanfla hosts extensive hard rock artisanal gold workings
· Historic drilling has returned high grade intersections, including (not true widths of interval):
o 5.1 g/t Au over 26m from 32m
o 4.3 g/t Au over 18m from 34m
· Passive seismic geophysical survey across karst-style targets to commence shortly
· Marvel is earning an initial 33% interest in the Project under the JV
· Altus holds a 2.5% Net Smelter Return ("NSR") gold royalty on Lakanfla
"We are excited to announce the commencement of a 3,800m drilling programme at our Lakanfla gold project in western
"The programme is being funded by our ASX-listed JV partner Marvel Gold, which is earning an initial 33% interest in the Project. We look forward to updating shareholders on the results from the drilling in due course."
Lakanfla Project: Drilling Programme
The planned 18-hole programme will total 3,800m and employ a multipurpose drill rig capable of Reverse Circulation ("RC") and
Passive Seismic Programme
Marvel will also be undertaking passive seismic surveys over the gravity lows at Lakanfla. These surveys are used to identify density contrasts between various lithologies up to 700m below the surface. Marvel believes the density contrast between dissolved carbonates and fresh rock can be used to model the base of the gravity lows in three dimensions. This data can then be calibrated against the drill results to aid target generation for follow-up drilling.
Summary of Joint Venture with Marvel Gold
Marvel have the right to earn up to an 80% interest in Lakanfla by sole funding four stages of exploration, culminating in a definitive feasibility study, and by making certain cash (or cash plus Marvel equity) payments to Altus. Thereafter, Altus has the right to co-fund or dilute its interest in the Project. Altus will retain a 2.5% NSR royalty on the Project and Marvel have the right to reduce the NSR to 1.0% for a payment to Altus of between

Lakanfla Project: Location
The 24km2 Lakanfla gold project is located 5km east of the Company's Diba ('Korali Sud') oxide gold project and approximately 6.5km southeast of the karst-type FE3 and FE4 open pits of the multi-million ounce Sadiola gold mine and 30km southeast of the former multi-million ounce Yatela karst-type mine. Lakanfla is bounded by the Sadiola permit area on its north, west and southern boundaries. Sadiola and Yatela are being acquired by Allied Mining from the existing operators Anglogold Ashanti (JSE: ANG, NYSE: AU and ASX: AGG) and IAMGOLD Corporation (TSX: IMG & NYSE: IAG). Mineralisation hosted on these properties is not necessarily indicative of mineralisation hosted at Lakanfla.
Lakanfla Project: Geology
Lakanfla hosts a consistent series of geophysical lows, as defined by a ground gravity survey completed in 2014. The lows are up to 0.5km wide and have a total strike length of approximately 4km. They are hosted within marbleised lithologies surrounding a granodiorite intrusion and its associated hydrothermal aureole. Surface sagging features, considered to be a result of the formation of dissolution voids at depth, have been mapped as being more than 100m long in places and these are also often coincident with the gravity lows. A number of the gravity lows are adjacent to N-S trending artisanal gold workings and are coincident with apparent gradient array IP resistivity lows. Interpretation of the residual IP anomalies has defined a series of intersecting regional and local shear structures, which are considered to have potentially promoted the karst formation process. The gravity lows and lithological trends may indicate areas of deep weathering of altered calcareous sediments, dissolution collapse and potential supergene gold deposition.
None of the priority gravity low targets defined by Altus have been systematically drill tested to date. Of the historical drilling that has been undertaken at Lakanfla, 35 holes coincide with the priority targets. However, the majority of these holes were drilled were no deeper than 75m vertical depth. One was drilled deep enough to test the karst potential, attaining a vertical depth of 161m. Critically, this drill hole (04KDD-08) was located on the margin of a gravity low, reached the target depth and terminated in loosely consolidated sand (from 165m to 171m), having also passed through voids and unconsolidated material. The Company considers that this hole provides strong evidence for the presence of a potential karst-type system.
Karst style deposits are known to form from the dissolution and collapse of carbonate (limestone) rocks. The weathering of these rocks, if originally mineralised with low grade gold and sulphides, can result in the precipitation of a higher grade 'supergene' and potentially economic gold mineralised residuum, above a more resistant basal layer. The dissolution of the limestones often means such deposits are associated with geophysical gravity lows, resulting from the formation of voids at depth. They may also contain sands and other more recent geological materials occurring unconformably in the geological sequence. These materials will have either been windblown, or collapsed into the depression created during the karstification (dissolution) process.
