Palito Operations


Coringa Project


Mike Hodgson, CEO of Serabi, commented:

The first quarter results for 2022 have been somewhat mixed . We have had some excellent , and better than anticipated results from the underground development at Coringa, most specifically on the first of the five ore zones, the Serra Z one. We have progressed development of V3 to the north and south of the ramp on both levels and these early results have been extremely promising . As we advance to the north, we also expect to see improved widths.

“At Palito, the first quarter p roduction results have been disappointing with 7,062 ounces produced, and while March was a significantly better month with improved grades and production , it was not possible to recover earlier shortfalls in planned production due to delays in receiving new mining fleet which while ordered in mid-2021 are only now built and becoming available for delivery. As a consequence, by having to rely on older machinery we have, in the short term, mined and process ed the ore in immediately accessible blocks, including those with lower grades , which contributed to lower than anticipated gold production over the last six months. However, a ll new items of fleet have been delivered or are expected to be delivered during the second quarter of 2022 and we are confident that we can increase production from the already identified new vein structures during the remainder of 2022 and in 2023.

At S ã o Chico , d ilution in the Julia Vein from mechanised long hole open stoping was also higher than expected as a consequence of the presence of parallel and cross cutting fault s and intrusive dykes which post-date the ore. T his level of faulting appears to be unique to the Julia Vein . We have therefore decided to ch ange the mining method on the Julia V ein and introduce selective open stoping, the method used successfully on the Palito orebody , and which will over time be ex pec ted to improve grades by minimising dilution through greater selectivity in the mining. 1,000 ounces of production which ha d been scheduled from S ã o Chico in February by long hole, will now be mined selectively during the second quarter and over the rest of the year.

Th e decision to mine selectively on the Julia V ein means the reliance on production ounces will, in the near term, focus on the Palito orebody, with operations at S ã o Chico focusing more on mine development with a view to a return to planned production levels later in the year and into 2023. In the short term we will be focus ing on producing profitable ounces and maximising operational cashflow rather than production growth for the rest of the yea r , and we are therefore revising our production guidance to be in the region of 30,000 ounces for 2022.

The real scale change on production ounces will be driven by the successful start-up of Coringa where we have enjoyed a very encouraging initial min e development . During the quarter, we intersected the three veins of the Serra Z one on the 340m and 320m levels. The results to date have been excellent, and as we develop the two principal veins, V1 and V3 to the north we are recording far better grades than forecast. As a result, we have introduced ‘ resue ’ development mining, where the ore and waste can be blasted separately. The advantage of this is that dilution of the ore coming out of the mine is minimised. The intention is to build a high-grade stockpile over the coming months.

On the permitting side, matters continue to progress well. We have had positive meetings with SEMAS, the State Environmental Agency . W e continue to expect this will result in Serabi receiving the LI in the coming few months .

Exploration results from the Palito Mine have been very encouraging. The Ipe and Mogno veins in the Chica da Santa sector, have demonstrated the depth potential and continued high grades of the sector. The Piaui sector hosts two veins, which have now been drilled over a strike length of 500m and 200m vertical depth. Plans are now being finalised to crosscut to this sector from the Senna vein later this year.

“The potential of Palito both along strike, at depth and now laterally is clear to see. From Pele in the east and Piaui in the west, the deposit now comprises a series of veins within a 1 , 000m wide corridor . Over the next 12 months, we will be expanding the Palito orebody considerably as we access these new sectors.

“Whilst the last two years have been tough operationally due to global supply chain issues and impacts of Covid, we are confident in Serabi’s future. The Palito orebody remains the engine room to our production base but with a turnaround expected at S ã o Chico this year and the material growth from Corin g a, our strategy remains to turn Serabi into a multi-asset gold miner with production approaching 100 koz within the next few years.

Cash balances at the end of March 20212 were US$6.9 million with a further receipt of US$1.6 million for a sale of copper/gold concentrate due to be received in early April. This receipt was delayed from March following late changes in sailing schedules. The reduction in cash holdings since 31 December 2021, reflects the continued development expenditure of Coringa during the quarter, and the reduced level of sales revenue generated in the period as a result of lower production.

The Company anticipates that the audited financial results for the Company for the year ended 31 December 2021 will be released in the middle of May.


In light of the issues identified during the first quarter of 2022 and the measures that the Company is putting in place, production guidance for 2022 has been reduced to approximately 30,000 ounces from 36,000-39,000 as previously for the full year.

"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.

Assay Results
Assay results reported within this release include those provided by the Company's own on-site laboratory facilities at Palito and these will not have 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
