Area 1 - Mine Life Extension Program
Sierra Rutile Limited
Sierra Rutile is currently undertaking a work program to convert Mineral Resources to Ore Reserves in order to extend the Area 1 life of mine plan.
Area 1 - Mine Life Extension Program Overview
•
Pejebu and Ndendemoia deposits are located less than 5km south of the MSP within
the Area 1 Mining Lease.
Subject to completing the technical and operational planning activities required to
convert Indicated Mineral Resources to Ore Reserves, mining at Pejebu and
Ndendemoia will be considered following completion of mining activities at Gbeni
and Lanti.
A mine life extension work program has commenced at both deposits, including:
additional geological drilling program and resource model update;
pit and civil infrastructure design;
operational planning including mine sequencing; and
financial modelling.
The work program is scheduled to be complete by mid 2023.
Area 1 - FY22 Extension Drilling
The 2022 drill program is focussed on collecting metallurgical and geo-metallurgical
data and improving Mineral Resource confidence as part of the ongoing LOM
program.
