Palito Near-Mine Exploration Success
Serabi Gold plc (AIM:SRB, TSX:SBI), the Brazilian-focused gold mining and development company, is pleased to announce further positive results from its ongoing regional exploration activity at its Calico target, which is located just 5km from the Palito Operation and Processing plant. In addition, initial regional soil geochemistry on the Sao Chico/Sao Domingos trend has recorded multiple significant gold and multi-element anomalies within this highly prospective mineralised corridor.

Identification of significant geochemical gold-in-soil anomalies at Calico, Juca and Forquilha, of which Calico is now very significant over a two kilometre by two kilometre area. Values as high as 0.8g/t gold have been recorded, better than have been seen in any soils over the Palito orebody.
Subsequent terrestrial geophysics survey using Induced Polarisation (“IP”) covering the Calico soil anomaly has identified multiple chargeability anomalies.
Both results are very comparable in terms of scale and signature to the Palito orebody, a 600,000 ounce resource, being mined today.
First pass drill-testing of the Calico prospect is planned in the coming months.
Multi-element soil anomalies confirm strike extension of known gold occurrences at the Fofoca prospect on the Sao Chico/ Sao Domingos trend.
Mike Hodgson CEO commented:
“These positive results from the regional programmes at Calico and Fofoca are very encouraging. After the interruptions to the exploration campaign of 2020 due to the pandemic, this year we are embarking on the most substantial exploration effort seen by Serabi to date. Whilst a key focus will be targeting resource growth at the existing Palito and Sao Chico orebodies, a significant part of the exploration programme is more regionally focussed whilst still within 20 kilometres of these producing orebodies. Both Calico and Fofoca fall into this category.
“At Calico the results to date are very compelling and, even at this early stage, lead us to start drawing positive comparisons with the Palito orebody. The Calico location was first observed as a significant electromagnetic anomaly from the airborne survey completed in 2018. In the Tapajos, such electromagnetic highs are typically indicators of sulphide bodies, which, as we see at Palito and Sao Chico and elsewhere, can often be gold-bearing.
“Calico is located just five kilometres from Palito, and in the past months we have completed follow-up terrestrial geophysical and geochemical surveys. The soil geochemistry programme defined several highly interesting anomalies, namely Calico, Juca and Forquilha, of which Calico is the most significant. Measuring two kilometres by two kilometres and with soil assays as high as 0.8g/t, this anomaly is comparable to the geochemical anomaly over the Palito orebody. This geochemical survey has now been complemented by IP which has proven to be very effective at Palito. The IP has highlighted a series of NW-SE anomalies, some sited within the bounding gold soil anomaly at depth and some adjacent to the soil anomalies. The orientation of these IP anomalies is consistent with broader regional structural fabric and the trend of the veins at Palito, just five kilometres away. Given its proximity to Palito and the fact that it shares many similar characteristics including what seems to be a similar geochemical and geophysical signature, we plan to conduct some initial first pass drilling during the coming months.
“The geochemical survey at Fofoca, located in the eastern part of the Sao Domingos tenement acquired by the Company in late 2020, is still in progress. The initial results have defined a number of new geochemical anomalies outside the multiple past and present artisanal mining areas. The survey will continue with a follow-up drill programme to be undertaken once this is completed.”

The Calico prospect and neighbouring Forquila and Juca prospects were initially identified from the interpretation of an airborne electromagnetic survey completed in 2018. These areas were initially selected where multiple electromagnetic anomalies (typically indicators of massive sulphides in the Tapajos), coincided with an ESE-WNW trending regional structure, known as Mato Cobra, a structure displaying strong magnetic and radiometric anomalism.
Reconnaissance field mapping identified alteration (potassic, haematitic and silicic) and evidence of weathered and primary sulphides in limited outcrop associated with felsic intrusive and volcanic rocks.
Systematic grid soil sampling subsequently identified a number of cohesive multi-element geochemical anomalies of which the most significant was the Calico prospect.
The Calico prospect is highlighted by a central potassically altered dacite porphyry intrusive with coincident higher temperature soil geochemistry multi-element signature of Mo-Bi-As-Te-W-Sn. This dacite porphyry intruding into a monzogranite was bounded by a broad 2km by 2km high gold/low antimony halo to the NW and anomalous copper wrapping around the southern part of the intrusive core.
The 50 metre by 200 metre grid soil sampling defined a broadly arcuate shaped two kilometre by two kilometre gold in soil anomaly defined by 1,532 soil samples, with a maximum of 0.8g/t Au, with 260 samples reporting analytical results between 0.03g/t and 0.8g/t Au. This gold anomaly is supported by a suite of multi-elements suggesting an intrusion related mineralising system (porphyry or intrusion related gold system model).
In 2020 Serabi completed a 44.5 line kilometre IP survey covering the gold in soil anomaly at Calico. The survey was completed on 200 metre spaced, north south orientated traverses, with an array designed to penetrate to at least 250 metres vertical depth.
The result of this survey has further refined the interpretation of the Calico prospect. The IP highlighted a series of NW-SE anomalies, as seen at Palito. These IP anomalies bound the gold soil anomaly and are adjacent to the dacite porphyry intrusive. Between these structures a series of transverse (NE-SW) and NNW-SSE structures (second and third order faults) have been identified which correlate with the peaks of the gold in soil assays.
With favourable geological mapping, coincidental IP anomalies and gold geochemical anomalies, the Company will be focussing on first pass drill testing of these targets in the coming months.

The assay results reported within this release 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. Based on the results of this work, the Company's management are satisfied that the Company's own facility shows good correlation with independent laboratory facilities. 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 but only use assay results reported by an appropriately certificated laboratory.
