Highlights
The Zonta Vein lies some 100 metres further west of the Senna Vein, which is in production, and once developed will be the most westerly production vein at Palito.
High grade intercepts from the recent underground drilling and some previous surface and underground drilling include:
0.55 metres @ 55.99g/t Au from 397.15 metres (PDD0289)
0.75 metres @ 34.75g/t Au from 217.00 metres (PUD0793)
1.00 metres @ 36.46g/t Au from 223.55 metres (PUD0801)
1.20 metres @ 10.65g/t Au from 300.80 metres (PUD0803)
1.00 metres @ 10.69g/t Au from 234.45 metres (PUG009)
Hole PUD0803 intersected the Zonta Vein at approximately 400 metres below surface and is currently the deepest intersection anywhere within the Palito Mine, boding well for future resource growth.
Mike Hodgson CEO said
“Underground drilling at the Palito Mine continues to deliver excellent results. This recent phase of drilling has intersected the Zonta Vein, an orebody that we had previously identified with limited surface drilling but had never properly drill tested. Most significantly, Zonta lies west of the Palito mine, meaning this is a new zone discovered between Senna – our most westerly developed vein and the Piaui zone, which was successfully drilled earlier this year. With minimal information between Zonta and Piaui, the possibility of finding multiple veins as we develop the mine to the west is high.
“Of further interest is the depth of some of these intercepts in the Zonta Vein. Hole PUD 0803 is 400 metres below surface, the deepest intercept in all of the Palito veins, recording 10.65 g/t over 1.20 metres and therefore indicating the veins remain robust at depth.
“Access and development of the Zonta vein is already underway with a simple cross-cut from the Senna Vein. and the resulting resource will make a meaningful contribution to our forthcoming mineral resource update and gold production in 2023 and 2024 .”
Results
The Zonta Vein is situated within the Palito Mine lease and extends the strike width of the Senna Sector as the most south-westerly vein identified in this immediate area. The Senna Sector is an area which is already being mined by Serabi and the significant existing mine infrastructure should facilitate rapid development of the Zonta Vein.
A further 500 metres to the southwest lies the Piaui Sector, (see news release dated 18 March 2022), an area that has been successfully drilled but does not have any underground mine development or infrastructure.

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. 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.
Holes PDD0255 to PDD0313 were drilled from surface in 2006, holes PUG001 to PUG011 were drilled from underground during 2016 and 2017 and holes PUD0793 to PUD0821 were drilled during this recent campaign.

“geophysical”

“geophysical techniques”
include the exploration of an area by exploiting differences in physical properties of different rock types. Geophysical methods include seismic, magnetic, gravity, induced polarisation and other techniques; geophysical surveys can be undertaken from the ground or from the air.
“gossan”
is an iron-bearing weathered product that overlies a sulphide deposit.
“grade”
is the concentration of mineral within the host rock typically quoted as grams per tonne (g/t), parts per million (ppm) or parts per billion (ppb).

refers to induced polarisation, a geophysical technique whereby an electric current is induced into the sub-surface and the conductivity of the sub-surface is recorded.
“intrusive”
is a body of rock that invades older rocks.
"Indicated Mineral Resource
is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.
"Inferred Mineral Resource”
is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.
“Inferred Mineral Resource”
‟ is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity.
