Geology Map of ZAMBIA

Exploration Works

Exploration has been in two phases. Initially, using geological sampling, radiometric scanning, pitting, and trenching to define the extent and grade of the eluvial tin deposit. The second phase, to define the extent and grade of the total tin deposit including hard rock is by drilling and analysis of the drill core.

Siankopo, the most evaluated lease to date, has 5 substantial sites which are suitable for mining. In particular, 2 sites are high grade (called the grave) and Kapongo Hill is lower grade but larger quantities.

Libra has confirmed ore resources of 10 million tonnes in Siankopo in the eluvial zone located in the top 2-3 meters. This eluvial zone is ideal for low cost open pit mining. Further drilling is required to define the extent of this ore body beyond the currently estimated 10 million tones. Drilling to depths of 30 meters is expected to intersect further ore resources.

Libra plans to carry out this drilling program as soon as possible to prove up ore resources and bring it to JORC levels. Laboratory tests and resource calculations are necessary to complete this stage. It is proposed to start at the area of the 3 veins that were found around pit no. 70 in Kapongo Hill in Siankopo (see Kapongo Hill map no. 2).

Libra plans to carry out this drilling program and metallurgical tests as soon as possible to prove up ore resources. It is proposed to focus in the area where 3 veins were found in pit no. 70 in Kapongo Hill in Siankopo (see Kapongo Hill map no. 2).

DRILLING PLANS

Drilling Tests and mining stages

Stage 1 of the drilling plan will be 20 holes adjacent to pit no. 70.

Stage 2 will be a further 130 holes drilled at 5 sites in Siankopo.

Stage 3 will be mineralogical and metallurgical analysis.

Particle analysis
Separation tests
Recovery tests
Metallurgical Flow sheet and optimization

Stage 4 – open cut mining.

Drilling Timetable:

 Preparation two weeks
 Drilling in the main vein one month
 Drilling in the second vein one month
 Preparation of the samples and delivery to the laboratory in Australia two weeks

Kapongo Hill contain the largest resource in our first tenement “Siankopo”; we also found 3 veins around pit no. 70 which will be our first target for drilling

The Grave area contain interesting concentration of minerals including 2 pits (98 and 114) of 15 and 20 PPM of Rhodium and Gold around pits 95 and 96
