Golden Rim Resources Ltd. announced results from geophysical surveys at its Kada Gold Project (Kada) in Guinea. Highlights: Golden Rim has received results for ground magnetic, gradient-array Induced Polarisation (IP) and pole-dipole IP geophysical surveys at Kada, covering both the Massan and Bereko prospects. Surveys identify multiple new drill targets for gold mineralisation outside Golden Rim's 930,000oz1 gold maiden Inferred Mineral Resource Estimate (MRE) area at Massan.

High priority targets associated with the margin areas between highly resistive and chargeable IP anomalies and highly conductive and chargeable IP anomalies. The widest and highest-grade mineralisation within the MRE area at Massan generally occurs proximal to these margin areas. A priority target for the follow-up drilling is a strong untested IP anomaly that lies directly below the previous drill intersection of 29m at 8.5g/t gold in KRC025 in the MRE.

Golden Rim will test new targets in its upcoming drill program, scheduled to begin in fourth quarter 2022. Infill drilling at Massan planned to enable Golden Rim to covert its Inferred MRE to Indicated category. Golden Rim contracted SAGAX to complete ground magnetic (82km), gradient-array IP (75km) and pole-dipole IP (6.6km) surveys at Kada, focused on the Bereko and Massan prospects.

The surveys were designed to enhance Golden Rim's understanding of the structural controls and distribution of the gold mineralisation. Magnetic and gradient-array IP lines were spaced at 100m, with a 25m station spacing along the lines. The shallow, ferruginous lateritic unit that covers the majority of Kada tends to obscure the magnetic signal of the underlying bedrock, however IP data has been immediately beneficial for increasing understanding of structural controls in the bedrock and identifying new drill targets in both Massan and Bereko prospects.

The gradient-array IP survey showed two parallel, north-south trending chargeability highs that extend for 1km across the MRE area at Massan, and then extend a further 1km south of the MRE area. The westernmost chargeability high is spatially associated with some of the highest-grade gold and broadest mineralisation in the MRE area. To better understand this relationship, four east-west pole-dipole lines were completed across Massan.

Two of these lines are in within the MRE area, and the other two lines are south of the MRE area across the width of the high-chargeability area. Analysis shows that most of the encountered gold mineralisation is associated with elevated levels of chargeability of varying amplitudes related to areas of stronger sulphide mineralisation, as well as conductive anomalies, which are associated with thicker areas of clay related to deeper zones of weathering. Gold mineralisation is often found near the margin between a wide, highly resistive and chargeable domain on the western side, and a highly conductive and chargeable domain on the eastern side.

The widest and highest-grade mineralisation within the MRE area generally occurs proximal to these boundaries. This insight, coupled with auger drilling gold results, has allowed Golden Rim to further refine regional drilling targets along the Kada Gold Corridor at both Massan and Bereko. Analysis in section using the pole-dipole IP data has also identified new drilling targets proximal to the MRE area.

The pole-dipole lines within the MRE area (lines 1,224,040m and 1,224,200m North) demonstrated that areas of high chargeability (>15mV/V) adjacent to the oxide-transition boundary or the base of complete oxidation (BOCO) often contain significant gold intersections, including: KRC025 - 29m at 8.5g/t gold; KRC018 - 20m at 1.6g/t gold; KRC011 - 16m at 2.1g/t gold; KDH007 - 20m at 1.1g/t gold; KRC023R - 9m at 2.2g/t gold (to End of Hole); KRC019 - 23m at 1.2g/t gold. A priority target for the follow-up drilling is a strong untested IP chargeability high anomaly that lies directly below the high-grade intersection of 29m at 8.5g/t gold in previous drill hole KRC025 and beneath the current MRE pit shell. There is an untested chargeability high that occurs on the oxide-transition boundary just 150m west of KRC025, which has had no drilling to date.

This target is also located outside the MRE pit shell and represents an opportunity to add additional ounces to the gold inventory at Kada. There are multiple instances of elevated chargeability values occurring proximal to the BOCO on the most southern pole-dipole line, over 500m south of the current MRE extent. This area is >200m from any drilling and provides numerous new drill targets, and an opportunity for further resource extension and potential satellite gold deposits.

In Bereko, magnetic and IP data indicate there are NW-SE trending faults that correlate to breaks within the main N-S trending auger anomalies. Mineralisation generally occurs in areas of high chargeability as seen at Massan, but north of the faulting this relationship is less clear. IP data has helped to identify multiple additional drill targets for investigation at Bereko, targeting high chargeability areas adjacent to a transition between high conductivity and high resistivity where there are broad bedrock gold anomalies.

Golden Rim's next drilling at Kada is scheduled to commence in November 2022. At Massan, there are two drilling programs are planned. The first is a resource extension RC program, focused on following up open intersections at the margins of the MRE (below KRC025 ¡ 29m at 8.5g/t gold), as well as on the open mineralisation to the north (KRC072 ¡ 66m at 1.0g/t gold).

The second and large program is an infill diamond and RC drilling program targeting the high grade and deepest oxide portion of the MRE, with the aim of converting a large proportion of the existing MRE from Inferred to Indicated category. In addition to this, 700m of trenching has been scheduled within this area to improve the geological understanding of the orientation and controls on the gold mineralisation.
