Robex: Kiniero Gold District Mansounia Central Exploration Results Including [email protected] g/t from Surface & [email protected] g/t from 3m

QUEBEC CITY, Nov. 28, 2022 (GLOBE NEWSWIRE) — Robex Resources Inc. (“Robex“, “the Group” or “the Company“) (TSXV: RBX) is pleased to announce exploration results on its property in Guinea.

Robex are excited to announce significant near surface gold intersects at the Mansounia Central Deposit, 3km south of the new Kiniero plant location at the Kiniero Gold Project in Guinea. The Robex geochemical gold-in-soil results have confirmed that the recently discovered Sabali South deposit (announced 24 May 2022) forms an integral part of the Kiniero Gold Mine restart. This now represents a part of a much larger shear mineralised corridor, termed the “Sabali-Mansounia” Corridor.

Key intercepts include:

  • MRC22-007: 40m @ 1.00g/t from 6m including 7m @ 2.07g/t from 34m
  • MRC22-014: 32m @ 1.32g/t from 0m including 4m @ 2.29g/t from 28m2m @ 1.36g/t from 49m
  • MRC22-042: 51m @ 2.64g/t from 3m including 21m @ 4.81g/t from 10m including 6m @ 3.17g/t from 42m.

Andrew de Klerk, Exploration Manager for Robex said: “These world class shallow intersects demonstrate the significant upside resource potential within close proximity of the new Kiniero process plant. A cumulative ~8km strike length of the “Sabali-Mansounia” Corridor represents one of the largest contiguous zones of gold mineralisation within the southern Siguiri Basin. We will further delineate this exciting deposit in early 2023.”

Robex conducted an extensive bulk leach extractable gold (BLEG) in soil geochemistry campaign, initially across the Kiniero license area, and then subsequently across the Mansounia license area. This reconnaissance targeting exploration campaign has remained ongoing since this date, running concurrently with the various technical mining, and drilling related studies that are actively underway to restart the Kiniero Gold Mine. The BLEG analytical technique has proven to be a very effective technique for accurately measuring fine grained gold content in the soils of this portion of the southern Siguiri Basin and has helped delineate drilling targets.

BLEG results to date have delivered some highly encouraging anomalies that define the Sabali-Mansounia Corridor. Drilling results from Sabali South have demonstrated a clear relationship between the BLEG gold-in-soil and the airborne magnetics, intrusives, the inferred alteration footprint, and the underlying confirmed structures. Structural interpretation of these combined datasets has yielded encouraging results providing additional structural understanding to the broader mineralised Sabali-Mansounia Corridor.

Based on this proven inter-relationship between the BLEG results and the drilling results, Robex decided to execute an RC reconnaissance and verification exploration drilling campaign targeting the Mansounia Central deposit that had been historically drilled by Gold Fields Limited (RAB scout drilling, 2003 to 2005) and Burey Gold Limited (RC and DD drilling, 2005 to 2012). In addition, the Mansounia Central deposit hosts the active Wadal Minji artisanal gold mine at which Robex has completed preliminary mapping and collected several mine grab samples, all exceeding 10g/t. The BLEG results, when interpreted against the historical drilling results, helped guide the targeting process of the Robex exploration drilling campaign to confirm the presence of mineralisation within the Sabali-Mansounia Corridor.

Twinning results of the Burey Gold Limited historical drillholes returned comparable mineralised horizons, both in terms of tenure of grade and intercepts, with local grade variances observed. The cumulative metal content was comparable, with high grade intercepts yielded in each of the twinned holes where expected:

  • MRC22-002 (20.89g of cumulative Au to a depth of 90m) twinned MRC227 (19.30g of cumulate Au to a depth of 90m)
  • MRC22-003 (37.96g of cumulative Au to a depth of 95m) twinned MRC156 (39.25g of cumulative Au to a depth of 99m)

Drilling results confirm the extensive presence of a well-developed upper supergene low-grade gold deposit, typically within the upper 30m, similarly as observed at Sabali South. Deeper mineralised horizons, from those holes drilled into fresh rock domains, exhibit classic stockwork mineralisation with brittle fractured, pervasively silicified metasediments and orogenic quartz-sulphide veining.

BLEG results has confirmed that the Mansounia Central deposit, within the Sabali-Mansounia Corridor drill target, represents a target area that is >1.5km in strike length and between 500m to 750m in width. The drilling completed to date, both historically and recently, has not yet constrained the full geographic extent of the mineralised corridor, suggesting a significantly larger footprint, which remains undrilled. Results returned from this RC reconnaissance and verification exploration drilling campaign at the Mansounia Central deposit confirms:

  • The accuracy and reliability of the historical data from the two twinned historical drillholes;
  • The proven relationship between the BLEG gold-in-soil and the airborne magnetics, intrusives, the inferred alteration footprint and the underlying confirmed structures;
  • A wide and continuous low-grade supergene gold mineralisation deposit across the the Sabali-Mansounia Corridor; and
  • That the Mansounia Central deposits represents a strategic near-plant (~3.5km), near surface oxide and fresh rock target for drilling to prove up additional Mineral Resources and Mineral Reserves for future mining at the Kiniero Gold Mine.
