Highlights
Underground drilling into the G3 Vein has demonstrated continuity of strong mineralisation below the current mined areas with intercepts including: 1.30 metres @ 44.75g/t Au from 337.85 metres (PDD0557)0.55 metres @ 45.20g/t Au from 190.60 metres (PDD0590)0.90 metres @ 23.33g/t Au from 286.30 metres (PUD0786)0.75 metres @ 24.92g/t Au from 230.00 metres (PUD0825)0.50 metres @ 32.11g/t Au from 238.10 metres (PUD0827) G3 has historically been a significant contributor to Palito’s production with approximately 65,000 ounces mined from surface to a vertical depth of approximately 300m and over approximately 800m of strike. The current drilling campaign is focused on testing a panel of potential mineralisation of approximately 300m by 600m that represents an extension of G3 to the northwest and down dip. Drilling planned for 2024 will test an additional southerly extension panel of approximately 500m by 500m.Good progress is being made with the Independent Mineral Reserve and Resource Estimate although it has been decided to include the current round of G3 drilling which will cause a delay in the completion of the estimate into the third quarter.Mike Hodgson CEO said
“Underground drilling at the Palito Mine continues to deliver excellent results. The G3 Vein was a major source of gold production for much of Palito’s earlier mine life with the benefit of also being one of the widest orebodies. With the deepening of other sectors within the mine, and particularly Palito West and Chico da Santa which are the sectors either side of the Palito Main Zone within which G3 occurs, drilling out the deeper portions of G3 is now becoming possible.
“In 2023 we plan to complete the drilling of the northwest extension of the G3 Vein, an area of approximately 300m of vertical extent and approximately 600m of strike. We also expect to be in a position to drill out the southeast extension of G3 in 2024, a panel with a vertical extent of approximately 500m and strike of approximately 500m.
“Given the success of the drilling we have taken the decision to include these latest results within the forthcoming mineral reserve and resource estimate. This will cause a short delay in completing the estimate although we still hope to have it completed in the third quarter.”
Results
The G3 Vein is situated within the Palito Main Zone of the Palito Mine and has historically been one of the most important sources of gold production with good continuity of width and grade. In total it is estimated that 65,000 ounces of gold has been extracted from the G3 Vein. Mining ceased when a fault structure was encountered, with limited drilling below this fault to justify further development.
With mining in the parallel sectors of Palito West and Chico da Santa extending to depth, it has been possible to position drill rigs to drill test the depth and lateral extent of the G3 Vein. The drill results demonstrate that mineralisation continues strongly below the fault although in places the fault can cause a minor off-set in the vein.
These results support the decision to advance development to lower levels in the northwest of the G3 Vein. Further drilling planned for 2024 should enable the southeast extension of G3 to be tested.

| Reported intercepts calculated based on a minimum weighted average grade of 0.5g/t Au (0.3g/t Au for historic results) using a 0.5g/t Au weighted average lower cut and a maximum internal waste interval of 1.2m based on ALS and Serabi´s on-site lab reported analyses. Some of the assay results reported above include those provided by the Company's own on-site laboratory facilities at Palito and have not been independently verified. Serabi closely monitors the performance of its own facility against results from independent laboratory analysis for quality control purpose. As a matter of normal practice, the Company sends duplicate samples derived from a variety of the Company's activities to accredited laboratory facilities for independent verification. Based on the past analysis of results of this work, the Company's management are satisfied that the Company's own facility shows sufficiently good correlation with independent laboratory facilities for exploration drill samples. The Company would expect that in the preparation of any future independent Reserve/Resource statement undertaken in compliance with a recognised standard, the independent authors of such a statement would not use Palito assay results without sufficient duplicates from an appropriately certificated laboratory. | |||||||||||

Assay ResultsAssay results reported within this release include those provided by the Company's own on-site laboratory facilities at Palito and have not yet been independently verified. Serabi closely monitors the performance of its own facility against results from independent laboratory analysis for quality control purpose. As a matter of normal practice, the Company sends duplicate samples derived from a variety of the Company's activities to accredited laboratory facilities for independent verification. Since mid-2019, over 10,000 exploration drill core samples have been assayed at both the Palito laboratory and certified external laboratory, in most cases the ALS laboratory in Belo Horizonte, Brazil. When comparing significant assays with grades exceeding 1 g/t gold, comparison between Palito versus external results record an average over-estimation by the Palito laboratory of 6.7% over this period. Based on the results of this work, the Company's management are satisfied that the Company's own facility shows sufficiently good correlation with independent laboratory facilities for exploration drill samples. The Company would expect that in the preparation of any future independent Reserve/Resource statement undertaken in compliance with a recognised standard, the independent authors of such a statement would not use Palito assay results without sufficient duplicates from an appropriately certificated laboratory.
