New Outcropping Mineralisation Discovered
at Nayega Manganese Project, Togo
Keras Resources plc, the AIM listed mineral resource company, is pleased to provide an update on the Company's low capex, feasibility stage Nayega Manganese Project in northern Togo ('Nayega' or the 'Project'), which hosts a current JORC 2012 Code Mineral Resource ("JORC Resource") of 13.97Mt @ 12.4% manganese. The Company recently commenced a 10,000 tonne bulk sampling metallurgical testwork programme which will include the processing of the beneficiated ore by a major producer of manganese-based alloys for commercial scale metallurgical testwork to assess the suitability of the ore in its manganese smelting facilities.
HIGHLIGHTS
· Identification of an additional 8 Hectares ("Ha") of outcropping manganese mineralisation in an area 400m east-west x 200m north-south, which appears to have been closed off to the south-east but is open in all other directions - named the Ogaro Prospect ("Ogaro")
· The new discovery demonstrates further upside and wider prospectivity of the Nayega Project - Ogaro is located 5km east-southeast of the main Nayega deposit and 4km south of the T27 deposit
· Positive results have been returned in samples collected from pits excavated to test the core area of mineralisation at Ogaro (14 pits totalling 35m). The best intercepts include: (see figure 1)
o 1.76m @ 18.6% Mn from 0m
o 2.05m @ 15.8% Mn from 0m
o 2.00m @ 16.2% Mn from 0m
· Potential to further enhance the total resource inventory of the Nayega JORC Resource of 13.97Mt @ 12.4% Mn
· Phase 1 pitting exercise on a 100m x 100m grid will commence immediately
Russell Lamming, Chief Executive Officer of Keras, commented,
"The identification of a significant new area of outcropping mineralisation at Nayega further lays the foundation and increases our expectations for what we believe will become a new low capex, low operating cost manganese producer. We have been very active in the area since approval from the Togolese Ministry of Mines was granted for the 10,000t bulk sampling testwork programme and we are looking to increase the current 14Mt JORC Resource. We have now employed a team from the local community which has, to date, been involved in the preparation of the bulk sample site and will now move over to the Ogaro area to commence a pitting exercise."
Ogaro Evaluation & Pitting
Reconnaissance mapping in the vicinity of the main Nayega orebody led to the discovery of outcropping manganese mineralisation at the Ogaro prospect in late 2017. Detailed geological mapping and reconnaissance pitting was completed thereafter with a total of 14 pits excavated for 35m total depth. As at the Nayega deposit, continuous vertical channel samples 10cm wide by 10cm deep were collected at 50cm intervals (maximum) from the top to the bottom of each pit; 82 primary samples were collected from the pits. A total of 106 samples, which included 24 quality assurance/ quality control ("QA/QC") samples as part of a rigorous regime to ensure the accuracy of results, were transported to Lomé for initial preparation at the laboratory for the department of mines in Togo, the Direction Generale des Mines et de la Geologie ("DGMG"), before being shipped to Intertek in Ghana for further processing and analysis.
Assay results have been received for all of the samples, with significant manganese intercepts returned in 9 of the 14 pits. Highlights include (all intercepts listed in Table 1 below):
· 1.76m @ 18.6% Mn;
· 2.05m @ 15.8% Mn; and
· 2.00m @ 16.2% Mn with Mn values peaking at 26.18% over a 0.5m sample.
Mineralisation can exceed 2m in thickness, occurring as detrital or lateritic accumulations of manganese within the regolith profile. Pits excavated to date have intersected this material over an area of 400m east-west by 200m north-south. Mineralisation, which can be concealed beneath barren ferruginous laterite, appears to have been closed off to the south-east but is open in all other directions. Pitting to confirm tonnage and grade and to test for extensions to identified mineralisation is planned. The location of the Ogaro Prospect is shown on Figure 1.

Analytical samples comprised vertical channel samples up to 0.5m long. Crushing of the samples was undertaken at the DGMG laboratory in Togo, the remainder of sample preparation was undertaken by Intertek (Tarkwa) with analysis by Intertek (Johannesburg) using lithium borate fusion with an XRF finish.
Intercepts were calculated on intervals >7.2% Mn with no included internal waste.
