Arrow Minerals gears up to drill advanced targets in Burkina Faso as it seeks to unlock gold potential of Boromo Belt
The company plans to undertake RC drilling in the current quarter and diamond drilling in the first quarter of 2022.
The company is focused on growing the known Dassa gold deposit and drilling several advanced targets, as well as working to define multiple high-quality anomalies for drilling.
Its objective is to define a critical mass of gold mineralisation in a small radius around highly prospective structural locations along the Boromo Belt.
The bulk of the work will be near Dassa, with concurrent regional definition along a newly acquired > 85-kilometre portion of the fertile Boromo Greenstone Belt, now accessible through a combination of 100%-owned permits and a recent binding term sheet to enter into a JV with Trevali Mining Corp (OTCMKTS:TREVF) (TSE:TV) (FRA:4TI).
Arrow managing director Howard Golden said: “Arrow is preparing to launch an aggressive program to unlock the immense potential of its position on the Boromo Greenstone Belt in Burkina Faso.
“With two deposits in hand, 12 prospects already advanced with high-grade intersections and a large swathe of the greenstone belt ready for exploration, we have the luxury of a target-rich environment in which to work.
“The collection of drilling and other enabling data on our significant portion of the belt will be a priority for Arrow for the remainder of the year.”
Boromo Belt with Arrow permits, Trevali permits and targets for 2021.
Trevali JV permit block
Trevali permits host multiple partly defined high-quality gold targets from limited historical work, including the Guido deposit.
The recent JV deal with Trevali has provided Arrow with a step-change in accessing highly prospective ground with widespread gold anomalism and multiple existing targets requiring drill testing within the next 12 months following modest additional anomaly definition work.
From 2009 to 2012 Blackthorn Resources explored for gold on permits currently held by Trevali and included in the recently signed JV agreement with Arrow.
Results from RAB, RC and diamond drilling include:
- 24 metres at 2.3 g/t gold from 18 metres;
- 2 metres at 7.6 g/t from 0 metres;
- 4 metres at 6.5 g/t from 6 metres;
- 417 metres at 2.4 g/t from 57 metres;
- 15 metres at 4.1 g/t from 39 metres;
- 4 metres at 3.2 g/t from 130 metres;
- 2 metres at 6.6 g/t from 26 metres;
- 4.3 metres at 4.4 g/t from 116 metres; and
- 4 metres at 5.2 g/t from 88 metres.
Trevali has also advanced work on their permits for gold as well as base metals, with RC drilling defining numerous high-grade zones for follow-up including:
- 4 metres at 11.45 g/t from 48 metres;
- 4 metres at >25 g/t from 12 metres;
- 4 metres at 12.5 g/t from 20 metres; and
- 4 metres at >25 g/t from surface.
100% Arrow permits
The results from the Trevali JV permits, combined with the Dassa and Dassa South deposit and mineralised zone respectively, and the Divole Main and Divole Fold nose zones already comprise a large gold-bearing district.
When added to the regional prospectivity across the Boromo Belt to be explored by Arrow it represents a very large and productive exploration space.
The Dassa deposit has shown 1-kilometre x 360 metres consistent gold mineralisation dipping shallowly from surface, largely in the oxidised zone including the following intersections:
- 6 metres at 4.0 g/t from 43 metres;
- 13 metres at 2.4 g/t from 6 metres;
- 12 metres at 1.2 g/t from 15 metres;
- 13 metres at 2.4g/t from 31 metres;
- 33 metres at 1.9g/t from 21 metres;
- 8 metres at 2.5 g/t from 112 metres;
- 13 metres at 1.4 g/t from 31 metres; and
- 14 metres at 3.2 g/t from 23 metres.
At Divole Main, Divole Fold Nose and Poa, intersections from RC drilling included:
- 9.9 metres at 4.3 g/t from 48 metres;
- 8 metres at 1.7 g/t from 125 metres;
- 17 metres at 1.2 g/t from 41 metres;
- 3 metres at 3.7 g/t from 53 metres; and
- 7.5 metres at 1.6 g/t from 65 metres.
In addition, Arrow also completed auger drilling in the southwest corner of Divole East, defining a high-grade coherent auger anomaly targeted for upcoming drilling.
Twelve-month Boromo Belt work program.
Proposed 2021 work program
The company is progressing towards its goal of consolidation of several advanced projects and deposits into a unified mineralised district.
Work proposed for the coming 12 months includes all stages of exploration to advance the many existing high-quality targets along the Boromo Belt, as well as regional studies to deliver more targets for testing.
