Centurion completes limestone gold panning program; starts auger sampling

Vancouver, British Columbia--(Newsfile Corp. - September 10, 2026) - Centurion Minerals Ltd. (TSXV: CTN) (" Centurion " or the " Company ") is pleased to announce that it has completed a reconnaissance panning and scouting program focused on the western portion of the Limestone Gold Project concession in Suriname. The program was designed to assess the distribution of alluvial gold and identify areas within the concession that warrant follow-up exploration. ( Figure 1 ).

Sampling Results

A total of 48 panning samples were collected during the reconnaissance program. Visible gold was identified in 41 samples, representing an 85.4% positive sample rate. Across all samples, 157 visible gold grains were recorded, with individual samples returning up to 18 visible gold grains.

The observed gold was predominantly fine-grained. Gold grains generally displayed a sub-angular morphology, particularly in the northwestern portion of the area. Several samples also contained medium-grained gold, while no coarse gold was recorded.

The presence of fine to flour-sized gold in the panned samples suggests that potential bedrock sources may occur within the sampled drainage basins. In several drainages, second-growth vegetation also indicated areas of historic small-scale mining activity that are not visible on satellite imagery.

The panning results were collected from an area interpreted to be underlain primarily by volcanic rocks, predominantly basalt, along with intrusive granodiorite. These interpretations are based on observations of weathered material examined during the scouting program.

Priority Exploration Targets

Based on panning results and geological observations from the scouting program, the Company has identified two significant priority targets for follow-up exploration.

Planned Auger Program

The next phase will consist of a shallow Ridgecrest auger program across the two priority target areas, identified as Targets 1 and 2 . The program will be similar to the approach used by Suralco (Alcoa) in the discovery of the Merian Gold Mine. Sampling will test soils and near-surface regolith along topographic highs that separate drainage basins where anomalous alluvial gold was detected through panning. The auger results will be used to refine the priority targets and guide subsequent exploration, including trenching and drilling.

Target 3 Mapping and Sampling

Target 3 comprises fluvial sediments from river terraces that are currently being mapped and sampled. Spoil piles from small scale mining pits in this area have returned pyritic silicified rock, suggesting the potential presence of favourable rocks for gold mineralization beneath the sediments.

Dr. Dennis LaPoint, President of Centurion, commented : " We are very pleased with the results and dedication of the team under difficult logistical conditions. A positive model for significant gold mineralization is being developed as geological observations continue."
