Roscan drills three m of 17.66 g/t Au at Kabaya

2021-05-04 06:16 ET - News Release

Dr. Andrew Ramcharan reports

ROSCAN GOLD SIGNIFICANTLY INCREASES DEPTH AND CONTINUITY OF MINERALIZATION ALONG STRIKE OF 600M AT KABAYA; ALL 52 HOLES DRILLED SINCE ACQUISITION INTERSECT GOLD MINERALIZATION

Roscan Gold Corp. has released positive DD/RC/AC (diamond drill/reverse circulation/air core) drill results from an additional 42 holes (29 DD and RC for 5,799 metres) totalling 6,500 metres at its Kabaya target, with all holes hitting gold mineralization.

At the time of acquisition on July 3, 2020, Kabaya's National Instrument 43-101 resource was pit constrained to a depth of 58 metres. Since the acquisition, all 52 holes DD/RC drilled by Roscan have intersected gold mineralization showing the remarkable continuity and consistency of the deposit. The company's January, 2021, drilling update (see news release dated Jan. 19, 2021) reported an increase of the depth potential of Kabaya (KB1) to 196 metres.

Subsequent drilling outlined in this release has now confirmed the continuity of the mineralization to a depth of 232 metres (KB1) over a strike length of 600 metres (KB1 and KB2), and it remains open. The recent drilling outlined below has dramatically increased the volume of the prospective deposit and has major positive implications for future resource growth. In addition, at the East Limb (KB2), the mineralization has now been extended down to 150 m in fresh rock from prior depth of 65 m and remains open at depth.

There were multiple holes intersecting high gold grades, such as drill hole RCDBS21-016, which intersected 17.66 grams per tonne gold over 3.0 m. While several holes showcased the broad consistency of the mineralization with intercepts such as 2.49 g/t gold over 19.0 m from drill hole RCDBS21-022, 2.29 g/t gold over 19.0 m from drill hole RCDBS21-016, 1.31 g/t gold over 21.0 m from drill hole RCDBS21-024 and 1.21 g/t gold over 30.0 m from drill hole RCDBS21-012, grade continuity and mineralization consistency reinforce the company's expectation for a robust new resource estimate at Kabaya by year-end.

In addition, shallow, regional stepout drilling has also revealed two newly discovered areas of high prospectivity, KB3 with 3.65 g/t Au over 4.0 m and KB4 with three g/t Au over 16.0 m, located, respectively, 1.0 kilometre north and 1.5 km south from the current resource footprint. It should be noted that KB4 lies on the magnetic trend that extends from Mankouke West into Kabaya over a 15 km strike, which has already yielded multiple high-grade intersections from earlier-stage regional drilling such as the company's KN2 and MS2 discoveries announced over the past few months.

Notes

(1) True width is yet to be determined.

(2) See the associated table for assay highlights.

(3) A grade of 0.5 g/t was used as cut-off with two m internal dilution for drill holes.

(4) There was no top cut.

Nana Sangmuah, president and chief executive officer, stated: "Since the acquisition in July, 2020, drilling at Kabaya has proven quite valuable as we have dramatically increased the continuity of the mineralization at depth over a strike length of 600 m and have identified the potential to tap into a deeper feeder system with both KB1 and KB2 open at depth.

"Kabaya has the potential to be a major contributor to our expected maiden resource update by the end of year. We have been very encouraged by our ability to more than triple the vertical extent of the deposit and show its robust continuity along strike. Newly discovered KB3 and KB4 zones could further expand the resource growth potential of Kabaya, and we will follow up with additional drilling in the weeks ahead."

The Kabaya deposit has a pit-constrained mineral resource to a depth of 58 m, which contains 105,000 ounces of indicated resource and 35,000 ounces of inferred resource. The company has now established mineralization to a depth of 232 m at KB1, which remains open.

The mineral resource is based on optimized pit shells using a gold price of $1,350 (U.S.) and a presumed heap leach gold recovery of saprolite material.

The gold mineralization at Kabaya is associated with albite-dolomite-pyrite alteration in greywackes and diamictites of the Kofi formation. The alteration observed in the core indicates a strong hydrothermal system commonly associated with gold deposits in West Africa.

Roscan believes that the Kabaya deposit is part of a significant structural corridor, which spans from Oklo Resources' discoveries of Seko and Disse to the northeast of the company's land package and then extends southerly for 15 km on the company's property from Kabaya to the company's recent Kandiole North (KN2) and MS2 discoveries and continues onto the recently acquired Mankouke West land package, which shows a strong magnetic signature similar to the other discoveries on this corridor. Much of this corridor has yet to be tested, and, thus, Roscan feels that the potential for new discoveries in this corridor is excellent and connecting these multiple targets with drilling will be a key priority in 2021.

Drilling and analytical protocol

Roscan uses air core, reverse circulation and diamond types of drilling in the Kandiole project. The air core drilling is mainly focused on drilling exploration targets.

The samples are sent for preparation to Bureau Veritas Mineral Laboratories in Bamako, Mali, and assayed at its analytical facilities in Bamako for fire assay with atomic absorption finish and by gravimetric finish for grades above 10 g/t Au.

Roscan applied industry-standard quality assurance/quality control procedures to the program using reference materials, blanks, standards and duplicates.
