Highlights

  • Shallow drilling confirms the continuity of three major parallel mineralised structures and identifies further smaller parallel zones.
  • Visible gold encountered in PDD0619 within a zone grading 2.6m @ 13.37g/t Au including 0.75m @ 33.74g/t Au from 28.55m.
  • High grade intercepts include:
    • 0.41m @ 16.89g/t Au from 26.40m, 1.94m @ 11.86g/t Au including 0.70m @ 19.15g/t Au from 35.30m (PDD0618)
    • 0.65m @ 14.28g/t Au from 43.1m, 5.90m @ 4.11g/t Au including 1.00m @ 17.56g/t Au from 69.75m (PDD0617)
    • 2.00m @ 3.69 including 1.00m @ 6.54g/t au from 12.0m (PDD0616)
    • 1.60m @ 2.70g/t Au including 0.50m @ 6.30g/t Au from 113.55m (PDD0612)

Mike Hodgson, CEO of Serabi, commented:

“The Piaui prospect is shaping up to be an excellent near mine opportunity for Serabi. This excellent set of drill results supports the strong results generated in 2011 with high grades over significant mineable widths. Piaui is close to the existing mine infrastructure and therefore can be brought into the mine plan in a short period of time and at low capital cost. We look forward to updating the market with further results when we complete a phase of deeper drilling later in the year.”

Results

The Piaui Prospect is located within the Palito Mine Lease, only 500m south of the mine infrastructure and underground mine development in the Senna and Zonta veins. It was identified in 2010 from a ground based induced polarisation survey undertaken as follow up to an airborne VTEM survey completed in 2008. Initial drilling results released in 2011 (news release dated 7 April 2011) reported a number of significant higher grade zones, including 2.57m @ 17.32g/t Au (PDD0459), 2.51m @ 6.20g/t Au (PDD0458), 10.73m @ 1.16g/t Au (PDD0456) and 4.50m @ 2.76g/t Au (PDD0455), within a strongly chlorite altered shear zone. Subsequent drilling in 2011 (news release dated 23 November 2011) reinforced the initial results with further intercepts including 5.21m @ 3.74g/t including 0.68m @ 14.00g/t Au (PDD0499), 3.40m @ 6.49g/t (PDD0506), 4.80m @ 2.72g/t Au (PDD0508), 2.00m @ 8.91g/t Au (PDD0511) and defined mineralisation over a 300 metre strike length within a strong hydrothermal alteration zone which was interpreted to remain open at depth.

In 2016, Serabi completed a series of bore hole electromagnetic (BHEM) surveys on the deeper holes drilled into the prospect to identify off-hole massive sulphide. As a result a series of conductors were defined occurring in two east dipping payshoots within the plane of the intercepted mineralised structures.

In 2022, Serabi have completed a further 10 drill holes (PDD0610 – PDD0619) into the two zones with the objective of refining the interpretation of the structures identified by the 2011 drilling, to faciliate a decision to extend mine development to Piaui. The first phase of the drilling targeted the mineralised zones within 100m of surface. The second phase planned for later in 2022 will target the BHEM anomalies.

Significant intercepts reported from the Piaui prospect are tabled below including some previously reported historic results from the 2011 drill campaign.

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.Note: Historic results have been re-assayed using the ALS independent laboratory and, this combined with re-compositing, accounts for the difference between these reported and the originally reported intercepts.      (1)   Since the original release of these results, samples have been re-assayed using the independent ALS laboratory and the intervals recomposited. Therefore the results reported in the table above may vary slightly from those originally reported..

“deposit” is a mineralised body which has been physically delineated by sufficient drilling, trenching, and/or underground work, and found to contain a sufficient average grade of metal or metals to warrant further exploration and/or development expenditures; such a deposit does not qualify as a commercially mineable ore body or as containing ore reserves, until final legal, technical, and economic factors have been resolved.
“electromagnetics” is a geophysical technique tool measuring the magnetic field generated by subjecting the sub-surface to electrical currents.
“garimpo” is a local artisanal mining operation
“garimpeiro” is a local artisanal miner.
“geochemical” refers to geological information using measurements derived from chemical analysis.
“geophysical” refers to geological information using measurements derived from the use of magnetic and electrical readings.
“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).
“g/t” means grams per tonne.
“granodiorite” is an igneous intrusive rock similar to granite.
“hectare” or a “ha” is a unit of measurement equal to 10,000 square metres.
“igneous” is a rock that has solidified from molten material or magma.
“IP” 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.
