Amarillo Launches 2021 Exploration Program at Mara Rosa
Amarillo Gold Corporation (OTCQB: AGCBF) has resumed drilling at its Mara Rosa Property in Goiás, Brazil, planning to drill 8,500 metres, comprising 6,500 metres of diamond drilling and 2,000 metres of reverse circulation. This follows a successful 2020 program that identified gold mineralization extending 1.5 kilometres. Key target areas include Pastinho, Estrela, Speti, and Filo and Sorongo, with significant historical findings at Estrela and other targets. The company emphasizes safety amid the ongoing Covid-19 crisis in Brazil while advancing its exploration efforts.
- Resumption of drilling at Mara Rosa Property, indicating active exploration efforts.
- Planned 8,500 metres of drilling includes multiple target areas.
- Historical data indicates strong potential at key targets like Estrela and Pastinho.
- Ongoing Covid-19 crisis in Brazil could impact operational efficiency and safety measures.
TORONTO, April 12, 2021 (GLOBE NEWSWIRE) -- Drills are turning again at Amarillo Gold Corporation’s (TSXV: AGC, OTCQB: AGCBF) Mara Rosa Property in the State of Goiás, Brazil. Amarillo is following up on the successes of its 2020 exploration program, which defined gold mineralization up to 1.5 kilometres in strike length, approximately 3.5 kilometres northeast of its flagship Posse Gold Project.
A total of 8,500 metres will be drilled, including 6,500 metres of diamond drilling and 2,000 metres of reverse circulation drilling, on four target areas close to the Posse Gold Deposit. Posse hosts proven and probable reserves of 902,000 gold ounces, as detailed in the Amended and Restated NI 43-101 Technical Report Definitive Feasibility Study Posse Gold Project, Brazil. Dated August 3, 2020, the report was compiled by SRK Consultores do Brasil Ltda with input from other engineering companies and consultants.
“Amarillo’s work in 2020 generated numerous high-quality drill targets within an 8-kilometre radius of Posse, several of which will be drilled for the first time this year,” said Mike Mutchler, Amarillo’s President and Chief Executive Officer. “We’ll focus on defining new zones of mineralization, initially emphasizing the Pastinho target.
“Last year, gold soil surveys, surface trenchwork, auger drilling, and limited diamond core drilling at Pastinho defined gold mineralization up to 1.5 kilometres in strike length. A recently completed induced polarization (IP) survey has defined chargeability anomalies that have aided in drill target selection.
“The Covid-19 situation in Brazil remains critical and our thoughts and prayers are with the people of Brazil at this time. Mining and exploration remain a crucial function for the Brazilian economy and we are working closely with officials in Mara Rosa city to ensure that our employees, contractors, and neighbours are kept safe by following proper Covid protocols coupled with a rigorous testing program.”
Priority 2021 drill targets
Drilling is planned at four priority target areas located nearby the Posse Gold Deposit: Pastinho, Estrela, Speti, and Filo and Sorongo. Pastinho, Estrela, and Speti are located along the North Posse Trend (Figure 1), and Filo and Sorongo is located in the Central Belt, about 5 kilometres northwest of Posse (Figure 2).
PASTINHO
The Pastinho deposit is located approximately 3.5 kilometres north east of Posse on 6,000 hectares of new exploration tenements that Amarillo gained access to in December 2019.
Limited drilling in 2020 defined a gold mineralized structure approximately 800 to 900 metres long oriented in a northeast-southwest direction along the same structural trend as the Posse Gold Deposit. The apparent thickness varies from 10 to 20 metres and dips about 60 degrees northwest.
Follow up surface trenching and shallow auger drilling extended the strike length of mineralization to about 1.5 kilometres (Figure 3). As previously disclosed, selected near surface drillhole intercepts include:
- 18.7 metres grading 0.84 g/t gold
- 11.0 metres grading 0.74 g/t gold
- 7.6 metres grading 1.45 g/t gold*.
Highlights of previously released surface trenching results include Trench 20TCH009 that returned 17 metres grading 1.46 g/t gold at the farthest northeast extent of the Pastinho deposit.
The planned drilling program will test the northeast strike extent and depth potential of the deposit.
Approximately 4,000 metres of diamond drilling is planned at Pastinho in 2021.
ESTRELA
Estrela is located about 6 kilometres northeast of the Posse Gold Deposit.
Amarillo completed a detailed soil survey and shallow auger drilling in late 2020 defining anomalous gold over a strike length of 1.4 kilometres and widths of up to 800 metres (Figure 1). A detailed IP survey is currently underway, and the results should help with drill target selection.
Historical work by previous operators highlights the potential of the target. For instance, Mineracao Colorado (BHP) started exploration work on the target in 1983 and completed 74 trenches and sampling in 1986-1987. This was followed by 45 hammer drill holes.
Two mineralized zones were reportedly defined up to 8 metres deep with grades of 4.0-5.20 g/t gold*. In 1993, Western Mining Corporation (WMC) is reported to have mined 4,615 tonnes grading 3.5 g/t gold (519 oz)*.
Amarillo has budgeted for up to 2,000 metres of diamond drilling at Estrela in 2021.
SPETI
The Speti target is located 2.2 kilometres northeast of the Posse Gold Deposit and interpreted to be hosted in the same northeast trending gold-bearing structure. Gold mineralization is characterized by strongly deformed and altered quartz-sericite schists hosting up to 1
Historical drill-testing returned 15 metres grading 0.62 g/t gold from 31.10 metres to 46.0 metres. This drill hole was oriented with an azimuth of 140 degrees and inclined at -70 degrees. The intersection width is estimated to be close to true width. A follow up drilling program in 2020 returned intercepts including:
- Hole 20P101 intersected 7.5 metres grading 0.77 g/t gold from 175.0 metres to 182.50 metres
- Hole 20P103 returned 2.5 metres grading 1.20 g/t gold from 37.5 metres to 40.0 metres
- Hole 20P111 generated 2 metres grading 1.14 g/t gold from 7.0 metres to 9.0 metres and 9 metres grading 0.47 g/t gold from 70 to 79 metres.
Importantly, anomalous gold values bottomed in several holes and require follow-up work to better understand the nature and extent of this mineralization. A ground IP survey was recently completed at Speti, and the results have aided in the selection of drilling targets.
Approximately 650 metres of drilling in three drill holes is budgeted at Speti in 2021.
FILO AND SORONGO
The Filo and Sorongo exploration concessions are located roughly 5 kilometres northwest of the Posse Gold Deposit along the same structure as the Zacarias gold deposit in the Eastern Belt (Figure 2). The Filo garimpo showing is a small shallow pit in oxidized material, with a few small shafts and pits from which some sulphide-bearing quartz veins were extracted.
WMC undertook a limited drilling program at Filo that outlined a historical reported resource of approximately 8,000 tonnes grading 2.88 g/t gold*. Some of the better historical drill results included 1.12 g/t gold over 4 metres and 2.11 g/t gold over 2 metres*. WMC reportedly did not drill outside the immediate area of the garimpo pit.
Sorongo is a larger garimpo pit compared with Filo, however, the mineralization and geology are similar. Mineralization is associated with a thrust fault and characterized by hydrothermal alteration, and brecciation and sulphide minerals along the sheared structure. Examples of historical drilling include 1.13 g/t gold over 2 metres with anomalous copper values, and 0.52 g/t gold over 1 metre*.
Amarillo has completed surface mapping, and sampling at the Filo and Sorongo showings.
An initial drilling program consisting of up to 1,000 metres is planned for these targets.
* These are historical results obtained from the reports and documents of previous operators and have not been independently verified by Amarillo.
