Manas Resources discovers major new soil anomalies up to 16km strike length at MGP

Manas Resources Limited (ASX: MSR) has announced encouraging regional geochemical sampling results over its Diellé permit at the Mbengué gold project (MGP) in northern Côte d’Ivoire, West Africa.

The company reported that the regional soil sampling results received from newly granted Diellé permit identified large gold-in-soil anomalies with strike lengths up to 16km with a peak response >2g/t Au.

MSR said that the follow up IP surveys and auger drilling is being planned.

Mbengué project

The MGP consist of two contiguous permits covering ~647km2 of the highly prospective Senoufo greenstone belt of northern Côte d’Ivoire, in close proximity to some of the region’s largest mines.

It is 6km north of Barrick’s Tongon mine (~4.5Moz Au), ~27km SE of Terranga’s Wahgnion mine (~2.7Moz Au), 40km southeast of Perseus Mining Limited’s (ASX: PRU “Perseus”) Sissingué mine (~1Moz Au) and 45km southeast of Resolute Mining Limited’s (ASX: RSG) world-class Syama mine (11.5 Moz Au).

Manas owns 100% of the Dielle permit (PR0857) and has an earn-in agreement for up to 70% ownership in the Mbengué permit, which is held by Occidental Gold SARL, a 100% owned subsidiary of Perseus Mining Limited.

Regional geochemical sampling programme

The company had recently completed a regional geochemical sampling programme covering the whole of the permit area (347km2). A total of 1,489 sites were sampled on an offset 500m by 500m spaced grid.

All samples were taken and analysed by multi-element ICP to ensure compatibility with previous Company sampling over the MGP.

Manas reported that it has now received highly positive results from the regional geochemical sampling programme.

Encouraging results reported

MSR announced that the newly discovered anomalies on the Diellé permit have the same geochemical associations (Au ± Ag ± Cu ± Fe ± Te) that the Company had previously confirmed as pathfinders for bedrock gold mineralisation elsewhere on the MGP.

Manas said that against a threshold of <5ppb Au, five of the samples assayed over 100ppb Au and the peak response was 2,026ppb Au (2.03g/t Au).

New major new soil anomalies

The company announced that a very large anomaly occurs along the Mbengué shear zone structure, which runs NE-SW for 16km through the southern part of the permit.

The company said that anomalous gold samples, including the sample grading 2,026ppb Au, are present along the whole 16km strike length.

MSR reported that the northern portion of Diellé has a lower background gold-in-soil level because of increased aridity and a thicker regolith. Here there are several point anomalies up to 250ppb over a 15km strike length of the parallel Toumoukro shear structure.

Manas said that Diellé is underlain by Birimian granitoid-greenstone lithologies and includes the continuation of geochemical and geophysical anomalies from the adjacent Mbengué permit.

Three shear zones

The three main structures within MGP are the NE-SW trending Tongon, Mbengué, and Toumoukro shear zones.

The Tongon and Mbengué shears are both associated with strong gold-in-soil anomalies over 10km long. They are also linked by a discontinuous NNW-SSE-trending gold anomaly (“Mamba”), which includes the Far West Target and is over 14km long.

Previous work at the Far West target had confirmed a strong IP chargeability anomaly over 2.5km long trending NNW-SSE (open in both directions) with a peak gold-in-soil response of 5,561ppb Au

IP surveys planned

Manas announced that the newly identified anomalies will be covered by IP geophysical surveys to identify targets for follow-up auger drilling.

It may be noted that this approach had successfully delineated major drill targets elsewhere on the MGP: recent results from the ongoing auger drilling programme include 2m grading 23.6g/t Au.

Next steps

The company announced that further exploration work will be planned in due course in order to define the extents of the large soil anomalies.

Management comments

Manas Chairman, Alan Campbell said: “The results from the newly-acquired 100% owned Diellé permit confirm the potential of the Mbengué Gold Project to host a major gold deposit. These newly discovered anomalies, with strike lengths to 16km, represent excellent targets for follow-up drill testing.

Manas aims to progress these targets, together with the ongoing auger drilling at the neighbouring Mbengué permit, as rapidly as possible before the seasonal rains arrive in late June / July.”
