Mike Hodgson CEO said

“It is very pleasing and a testament to the hard work of the team at the Palito Complex that we have managed to produce 2,919 ounces in April. As investors will recall we experienced production challenges in the first quarter on the Julia Vein at Sao Chico, and this resulted in us moving away from sublevel long-hole mining method, for the more selective, albeit slower shrink stoping method. So it is really pleasing to see this change bearing fruit coupled with continued excellent performance at Palito. The mining teams are working hard to maintain this level of production over the coming months.

“Development at the Coringa project has also continued apace and we have generated a high-grade sample on surface of [366] tonnes with a grade of [17.76] g/t gold from underground development. On-lode development has now been extended to over [60] metres primarily along the V3 vein of the Serra ore body on the 340m and 320m levels. The vein has been mapped and sampled as we advance providing us with an excellent 3-dimensional understanding of the ore zone. So far it is shaping up better than we could have expected. Not only have grades consistently exceeded our expectations but also parts of the vein are sufficiently wide and continuous to allow for split blasting where we blast the ore and waste separately. This enables us to remove a less diluted and therefore higher grade product from the mine. The combined impacts of both the higher grades and split blasting have enabled us to generate such a high grade preliminary bulk sample. We look forward to trucking this to Palito to run it through our plant. I also want to draw investors’ attention to the photos attached, I think it is very clear the contrast between the vein material that hosts the gold and the red coloured waste rock, in this case granite. I think it goes without saying we are very hopeful of excellent results from the forthcoming ore sorting test-work.

“The third leg of the Serabi story is exploration and it is very pleasing to be able to report some positive exploration drilling from the Matilda prospect. The Matilda target was generated by extensive field work including mapping, geophysics and geochemistry. Three scout holes have been completed to test the 4km by 4km target with each intersecting porphyry material with significant sulphide content. Although we are awaiting assay results, hitting a mineralised porphyry with the first three holes ever drilled on such a large target is fantastic. The core is being logged in detail and we look forward to updating the market when the assay results are received.”

RESULTS

Palito Complex ProductionThe Company produced a total of 2,919 ounces during April, from the processing of 14,252 tonnes grading at 6.86 g/t gold. Total mined tonnage for the month was 13,223 tonnes @ 6.82 g/t gold.

Coringa DevelopmentSerabi commenced the main ramp into the Serra Zone in July 2021. The ramp is a four metre high and four metre wide gallery. The ramp traversed all three lodes that comprise the Serra Zone, perpendicular to strike. The Serra Zone is approximately 30 metres wide, with approximately 15 metres separating each vein. This first development lies on the 320 metre level, approximately 50 vertical metres below the portal entrance. Three metre high and three metre wide ‘on-lode’ development has now been advanced, following the veins along strike to the north. A smaller ramp has been driven off the main Serra ramp, rising up to level 340 metres, where again all three veins have been intersected and similar on-lode development undertaken. This underground development is mapped and sampled providing a significantly enhanced understanding of the ore-body.

Initial on-lode development has focused on the V3 vein with [62] metres of sill drive completed on both the 320m and 340m levels to date.

The assay results reported above are 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. 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.

The V3 vein is sub-vertical (on average dipping steeply 75°-85° to the NE), which is highly beneficial for mining. Given the grade and continuity of sections of the V3 vein thus far encountered, split blasting of development faces or resue mining is being undertaken. Waste is initially blasted and removed followed by the ore, thereby significantly reducing the dilution that normally occurs with on-lode development. Development ore is hauled to surface and the first bulk sample of 894 tonnes at a grade of 8.25 g/t gold has been stored in stockpiles on surface. These stockpiles include a high grade sample containing 366 tonnes at a grade of 17.76 g/t gold with the balance of 528 tonnes at an average grade of 1.66 g/t gold.

The intention is to truck these bulk samples to the Palito processing facility to test the high grade material through the plant and the lower grade material through the ore sorter. The strong contrast between the ore and waste is evident from Figures 3 to 5 above and therefore the ore body is expected to be extremely amenable to ore sorting.

Figure 6: Serra Mine split blast sequence.

On-lode development will continue on the V3 vein and begin on the V1 vein, further demonstrating the continuity of the ore body but also expanding the on surface stockpiles.

The V2 vein structure, which was intersected by the two ramps, remains narrow in the south of the deposit but, based on drill hole data, is expected to become more significant further to the north into the main part of the Serra Zone.

ExplorationThree drill holes have been completed at the Matilda target in the Palito Complex tenement area. Matilda, which lies to the west of the Sao Chico mine was defined as a priority exploration target following extensive exploration including geophysical surveys, soil geochemical programmes and field mapping. A significant 4km by 4km soil geochemical anomaly was defined with 2km by 2km Au-Cu-Mo-W core, coincident with anomalous high magnetic susceptibility believed to be associated with magnetite alteration. Granites with potassic, propylitic and sericite-chlorite alteration have been mapped on surface along with dacite porphyry and quartz-sulphide veins.

To access a plan of the Matilda target please use the following link https://bit.ly/3l1bS4J

Figure 7: Plan of Matilda target showing geochemistry and geophysics.

No previous drilling has been completed on the prospect and, given the scale of the geochemical anomaly, the initial drill holes were scout holes positioned to test the central portions of the anomaly. All three holes intersected porphyritic material containing significant sulphides including chalcopyrite and molybdenite. Logging of the holes is ongoing and samples have been sent to an external laboratory for assay. Results will be released when received.
