Positive Results from Mabale Hills Project in
Tanzania.
Recent drilling by Sub-Sahara, on behalf of the Lake Victoria Joint Venture with
Canadian listed Currie Rose Resources Inc. at the Mwamazengo gold discovery (Mabale
Hills Project) in central Tanzania, has confirmed the earlier drilling results with gold
mineralisation extending to 110 metres vertical depth. Gold mineralisation remains open
at depth and along strike (Figure 1).
Drill Highlights - Mwamazengo Prospect - Tanzania
MBNR-005 intersected 3 metres @ 5.08g/t gold from 17 metres
MBNR-007 intersected 12 metres @ 9.11g/t gold from 57 metres
MBNR-009 intersected 13 metres @ 2.07g/t gold from 80 metres
MBNR-015 intersected 59 metres @ 2.75g/t gold from the surface
Including 4 metres @ 16.71g/t gold from 38 metres
The current programme of 2,387 metres of drilling consisted of 14 Reverse Circulation
(RC) drill holes totalling 1,444 metres and 13 Rotary Air Blast (RAB) drill holes totalling
644 metres at Mwamazengo with a further 10 RAB drill holes at Sisu River totalling 299
metres.
The 14 RC holes were designed to test the continuity of mineralisation discovered during
the March drilling campaign at the colonial Mwamazengo workings while the RAB
drilling at Mwamazengo was designed to test for potential parallel mineralisation and
strike extensions. The RAB drilling at Sisu River was designed to test high grade rock
chip samples and the possible strike extension of the Kitongo gold discovery (outside the
license area).

At Mwamazengo, previous RC drilling had identified a significant, structurally controlled
gold target on the western limb of an anticlinal fold closure within an intercollated
package of BIF, tuff and schists. The current drilling has:
• Confirmed mineralisation down to 110 metres vertical depth
• Confirmed oxide gold mineralisation from the surface
• Intersected significant infill gold mineralisation
• Confirmed mineralisation over 250 metres
• Confirmed that oxidation extends to approximately 75 metres vertical
depth.
Three of the 14 RC drill holes were unsuccessful in reaching their target depth but the
remaining 11 drill holes successfully reached target and intersected gold mineralisation
(Table 1).

Two fences of RAB drilling at the northern and southern extension of Mwamazengo did
not intersect significant mineralisation but returned weak anomalism in 4 drill holes. At
this early stage, this may be due to the depth of drilling which on average reached about
45 metres vertical depth and as yet, there has been no plunge determination for the
intersected mineralisation and deeper drilling will be required.
As a result, a close spaced ground magnetic survey is in progress and an IP geophysical
survey is planned to start at the conclusion of the magnetic survey. Both these surveys
will add information with respect to the lithological contact and the presence of sulfide
that may be significant in the overall interpretation.
The RAB drilling program at the Sisu River anomaly situated 10km north-northeast of
the Mwamazengo discovery was restricted by poor rig access allowing only partial
testing of the anomaly that returned gold grades up to 553g/t gold from rock chip
sampling. A ground magnetic survey will be completed and better drill rig access
secured.
Sub-Sahara is very encouraged by these results and plans are in progress to secure a drill
for the next program to coincide with the completion of the magnetic and IP geophysical
surveys.
