Panthera Resources Plc (LON:PAT), the diversified gold exploration and development company with assets in West Africa and India, has reported exceptionally high-grade gold in soil anomalies from the recently completed sampling programme at its Bido project in Burkina Faso, West Africa. PAT is earning up to 100%, ex any government interest, in the Bido project.
· Survey completed with 1,166 soil samples collected on lines 200m part with samples every 50m along lines, together with assays
· Several high-grade gold in soil assays received including some individual, point samples:
– 26,500ppb Au (26.5g/t Au)
– 16,700ppb Au (16.7g/t Au)
– 4,150ppb Au (4.15g/t Au)
– 3,720ppb Au (3.72g/t Au)
– 3,060ppb Au (3.06g/t Au)
– 2,100ppb Au (2.1g/t Au)
· Identified a northwest-trending zone approximately 2,500m long that is contourable at 32ppb Au with a 1,600m core area that is contourable at 64ppb Au
· New gold rush by artisanal miners identified north of the recent sampling area at Beredo prospect
Mark Bolton, Managing Director of Panthera, commented:
“The survey results are excellent and confirm that this area has the potential for high-grade mineralisation.
The next stage of work will involve infilling gold in soil sampling of some of the better anomalies, detailed geological mapping and rock chip sampling, and possibly some trenching and geophysics. Subject to these results, we anticipate a drilling programme mid-2021.”

The Bido project is located in southern Burkina Faso, approximately 120km WSW of the capital city Ouagadougou.
Bido is situated within a well-endowed Birimian greenstone belt that hosts the Konkera (3.3Moz), Gaoua (3.4Moz), Wa (2.0Moz) and Poura (1.0Moz) gold deposits to the south and the Karma (5.0Moz), Kalsaka (1.2Moz) and Bissa (5.5Moz) gold deposits to the north. In addition, a large zinc deposit, Perkoa (0.63Mt Zn), is located about 35km to the north.
A total of 1,166 soil samples have now been collected, assayed and results received. Several very high grade assays have been returned including:
· 26,500ppb Au (22.6g/t Au)
· 16,700ppb Au (16.7g/t Au)
· 4,150ppb Au (4.15g/t Au)
· 3,720ppb Au (3.72g/t Au)
· 3,060ppb Au (3.06g/t Au)
· 2,100ppb Au (2.1g/t Au)
These are extremely high for gold in soil samples and are interpreted as reflecting the residual nature of the soil profile and the common occurrence of nuggety gold in the region. One of the modus operandi of the local artisanal miners is the use of metal detectors which prove to be very useful for locating the coarse gold nuggets.
However, these high-grade samples are located in areas that have not as yet been targeted by the artisanal miners, indicating significant untested exploration potential including several zones of mineralisation.
Interestingly, while the new artisanal gold rush at the Tiekouyou Rush prospect shows anomalous gold in soil, much higher values and more consistent anomalies are noted elsewhere.
The work has identified a major northwest-trending zone of anomalous soils over an area of approximately 2,500m by 200m that is contourable as 32ppb Au with a core zone of 1,600m x 100m that is contourable at 64ppb Au with a peak value of 147ppb Au (0.15g/t Au).
The very high-grade samples are less continuous but it is suspected that this may be due to the skeletal soils and the broad sample spacing of 200m x 50m. If the mineralisation is less than 50m wide (i.e. narrow high-grade quartz veins) then it will be easy to miss at this spacing.
It is suspected that the 3.27g/t Au and the 16.7g/t Au results may be part of the same NNW trending mineralisation system at Tiekouyou West and geological mapping, infill sampling and probably trenching and geophysics are proposed to test this concept.
The large main anomaly at Tiekouyou East is a high priority target given the size potential, and additional geological mapping, rock chip sampling, infill soil sampling and possibly trenching and geophysics are planned in order to define drill targets for the second half of 2021.
The Tiekouyou Rush prospect is more difficult to define, with both north-south and north-westerly trending features interpreted. A similar programme to that proposed for Tiekouyou East and West is proposed in order to define drill targets.
During this work, a new mini “gold-rush” was noted in an area within the main target zone at the Beredo prospect. The artisanal miners appear to be targeting angular scree (not transported far) close to the Bido vein and within a strong northwest trending geochemical anomaly. This is encouraging and has significantly increased the priority of this target.
The area is currently being mapped in detail as part of the ongoing geological mapping and rock chip sampling program designed to determine drill targets for the second half of 2021, possibly following trenching and/or geophysical surveying if considered warranted.
The Bido project is taking shape as an excellent exploration opportunity with numerous untested gold in soil anomalies, some with extremely high grades and others with significant size potential. A model is emerging with the mafic units being a favoured host, with potential large scale “ladder veins” cutting across it in a northwest direction (e.g. Beredo and Tiekouyou). Other major target zones appear to be related to contact zones such as Somika and Kwademen.
