TORONTO, Sept. 14, 2020 (GLOBE NEWSWIRE) — Outcomes from a floor exploration program help the speculation that there are further near-surface gold deposits alongside the Posse North Gold Pattern, stated Amarillo Gold Company (TSXV: AGC) (OTCQB: AGCBF) as we speak.
Since February 2020, floor work on the Firm’s Mara Rosa Property in Brazil has targeted on trenching and auger drilling to delineate the higher-grade zones of anomalous gold on floor alongside the development. The continued intention is to establish probably financial gold deposits that would add to current sources and reserves, which might improve the manufacturing profile of the Posse Gold Mission.
“We’re beginning to notice the district scale potential of the Posse development,” stated Mike Mutchler, Amarillo’s Chief Government Officer. “These thrilling outcomes are in step with the outcomes of our profitable November 2019-February 2020 drill program, which confirmed the potential for satellite tv for pc gold deposits at Mara Rosa.
“A brand new useful resource would give us the choice to increase the deliberate lifetime of the Posse Mine, broaden the plant throughput, or some mixture of each. This may considerably enhance the challenge’s anticipated returns.”
The floor exploration program targeted on three targets. Pastinho, Lambari, and Estrela are positioned 3.5 kilometres, 4.5 kilometres, and eight.Zero kilometres northeast of the Posse Gold Deposit alongside the Posse North Pattern (see Determine 1).
Posse North is a northeast trending potassium-radiometric anomaly with coincident gold in soil anomalies better than 50 components per billion outlined by earlier work. Structural options discovered by airborne magnetics had been additionally helpful guides for concentrating on.
A mechanical back-hoe loader dug three-metre-deep trenches usually at each 200 metres. Chip channel samples had been taken at one-metre intervals for every trench, which had been oriented in a northwest-southeast course and perpendicular to the primary development of the gold deposits.
The important thing findings of the floor exploration program are:
- floor trenching and auger drilling verify the up-dip extension of the Pastinho gold goal
- the floor soil anomaly at Pastinho has been outlined over a strike size of 1.5 kilometre and stays open alongside strike to the northeast
- there seem like subparallel gold constructions with as much as 5 mineralized gold zones trending northeast alongside the Pastinho goal.
- Lambari and Estrela have outlined gold anomalies that require follow-up work.
The Pastinho goal
Pastinho is 3.5 kilometres northeast of the Posse Deposit on 6,00Zero hectares of recent exploration tenements that Amarillo gained entry to in December 2019. It’s a gold mineralized construction roughly 800-900 metres lengthy oriented in a northeast-southwest course alongside the identical structural development because the Posse Gold Deposit. The obvious thickness varies from 10-20 metres and dips about 60 levels northwest.
Geologically, Pastinho is just like Posse. It’s characterised by a hydrothermally altered thrusted shear zone developed alongside the contact between a biotite microcline gneiss (granodiorite composition) and metagabbo and/or amphibolite mafic rocks. There are structural materials together with mylonites along with hydrothermal alteration minerals like silicification (quartz), biotite, sericite, and carbonate with related disseminated sulphides which can be usually 1-3% pyrite.
The outcomes of Amarillo’s most up-to-date diamond drilling are interpreted to have elevated the strike extent to 900 metres (see Determine 2) from the 150 metre lengthy zone of near-surface gold mineralization outlined by a earlier operator. Examples from these drill outcomes embody:
- gap LMR007A – 18.7 metres grading 0.84 g/t gold. It was oriented with an azimuth of 109.1 levels and a dip of -50 levels.
- gap 20P109 – 11 metres grading 0.74 g/t gold. It was oriented with an azimuth of 125 levels and a dip of -59 levels.
9 trenches (see Figures Three and 4) had been dug totalling 791.6 metres, and 850 samples had been examined over a strike size of 1.5 kilometres (see Desk 1). Highlights of the outcomes embody:
- trench 20TCH001 – 20 metres grading 1.034 g/t Au
- trench 20TCH002 – 11 metres grading 0.95 g/t Au
- trench 20TCH003 – 10 metres grading 1.22 g/t Au
- trench 20TCH004 – 5.1 metres grading 3.27 g/t Au
- trench 20TCH009 – 17 metres grading 1.46 g/t Au.
Considerably, the floor trench work has prolonged the strike size of the Pastinho gold goal to 1.5 kilometres. The present interpretation is that the floor trenching program has outlined the up-dip extension of Pastinho. There seem like as much as 5 subparallel gold constructions dipping northwest roughly 50-60 levels. Pastinho, which has been drill-tested to a depth of roughly 100 metres, stays open at depth.
Lambari is positioned roughly 1.Zero kilometre northeast of Pastinho, and 4.5 kilometres north of Posse. The geological setting of Lambari is just like the Posse Gold Deposit and Pastinho.
Floor work consisted primarily of shallow auger drilling, which outlined two gold in soil anomalies. The primary anomaly is positioned alongside strike and parallel to Pastinho and has a strike size of roughly 1.Zero kilometre. The second gold in soil anomaly happens to the northeast and is parallel to the primary anomaly. It has been outlined over a distance 1.5 kilometres.
Estrela is positioned about 3.5 km northeast and alongside development from Pastinho, and roughly 8.Zero kilometres northeast of Posse. Estrela is interpreted to happen alongside the identical structural hall as Posse and Lambari and shares comparable geology. Work consisted primarily of shallow floor auger drilling and outlined a northeast trending gold in soil anomaly over a strike size of 900 metres.
Future exploration program
The floor exploration work at Mara Rosa has been profitable in higher defining the Pastinho, Lombari, and Estrela gold exploration targets.
Along with on-going floor trenching and auger drilling of chosen targets, subsequent steps may even embody finishing an in depth induced polarization floor geophysical survey over every of the targets and a diamond drill program.
Floor geophysics is predicted to start in late September or early October, with a diamond drilling program deliberate to start in late 2020 or early 2021. Roughly C$1.75 million has been budgeted for exploration at Mara Rosa to the top of 2021.
