Changara Manganese - Mozambique

Keras holds an 85% interest in the Nayega manganese project in northern Togo, which consists of five Exploration Permits covering 92,390 hectares. The project is 30km from a main road which has direct access to the regionally important deepwater port of Lome 600km away and has >500,000t per annum back loading capabilities. Based on work conducted to date the Company is confident that the project will provide cash flow for the Group through the rapid development of a low-capex, open pit, 250,000tpa manganese ('Mn') 38% Manganese product operation (Phase 1) and in the medium-term commissioning a smelting facility to produce a valuable 74% High Carbon Ferromanganese alloy (Phase 2).

The Measured Resource at Nayega totals 2.0Mt at 17.1% Mn, enough to cover the first three years of proposed manganese mine life, and the total resource for Nayega now stands at 11.0Mt at 13.1% Mn, all in the Indicated and Measured categories. Exploration outside of the resource area has defined additional targets, which have the potential to increase the size of the manganese resource.

The majority of the Phase 1 Definitive Feasibility Study has been completed at Nayega to develop the initial open-pit, 250,000tpa manganese operation. The mine design, schedules and tailings dam design have been completed based on cash operating costs of US$2/Dry Metric Tonne Unit ('DMTU') FOB. DRA, a leading South African gravity plant specialist, has finalised the processing and local infrastructure study and the environmental and social study was submitted to the Ministry of Environment earlier in 2014 and was granted in October 2014. With the Environmental Permit secured Keras is continuing to focus on finalising the Definitive Feasibility Study and securing the Mining Permit.
