TEMBO REPORTS ARTISANAL SAMPLING RESULTS OF UP TO 32.64 G/T GOLD
Tembo Gold Corp. has released new assay results from routine sampling of artisanal ore from active workings at Ngula 2, Mgusu, Nyakagwe East and Nyakagwe Village targets at the Tembo project in the Lake Victoria goldfield of Tanzania. Tembo has commenced monthly routine sampling of material being extracted to surface by local miners. This sampling will provide a detailed database of values and a clearer understanding of average mineralization grades and variability at each target where mining is active and will assist in the prioritization of targets. The May sampling results ranged in grades from less than one gram per tonne (g/t) gold to greater than 38 g/t gold with average grade of 9.88 g/t.
A Tembo geological technician has visited the artisanal mining areas at the four targets and collected random grab samples varying in weight between two and three kilograms from the miners at each site. These samples, an accumulation of material from the current workings, constitute samples of the mineralized veins and shears at each working. The samples were submitted for analysis to the SGS laboratory in Mwanza, Tanzania. The detailed assay results are shown in the associated table.
The samples returned average grades as follows:
- Nyakagwe Village: 9.53 g/t and 9.41 g/t gold from two vertical shafts at
depths of 20 metres to 25 metres;
- Nyakagwe East: 1.48 g/t, 7.34 g/t, 4.28 g/t and 8.05 g/t gold from four
shafts at depths of 13 metres to 20 metres;
- Mgusu: 7.23 g/t and 3.95 g/t gold from two shafts approximately 10 metres deep;
- Ngula 2: 32.64 g/t and 0.67 g/t gold from a 30-metre-deep shaft and one-metre-deep
shallow pit, respectively.
Nyakagwe Village
This area consists of an east-west-trending zone with semi-continuous historic mining along a strike of 1.7 kilometres and a second area of current mining about 300 metres long and 100 metres broad on a north-south trend. The latter working has been developed over the past 12 months and has grown from a series of shafts in a grid pattern to a large open pit. Geological indications in the pit suggest the intersection of north-south-trending and east-west-trending structures intersecting and controlling the mineralization and there is evidence of widespread brecciation and mineralization of the surrounding metavolcanic host.
Nyakagwe East
Possibly as many as four close-spaced parallel workings form a broad area of 300 metres of surface and underground mining with a strike extent of approximately 750 metres which trends 290 degrees to 320 degrees. Numerous shafts have been mined along the trend in parallel zones and currently active shafts vary in depth to 20 metres. Historic diamond drilling carried out at Nyakagwe East in 2008 returned significant results within prominent shear zones that hosted quartz veins and pyrite sulphide mineralization over widths up to four metres and greater. Best results achieved included 10.25 g/t over 3.5 metres, 2.46 g/t over 4.72 metres, 9.8 g/t over 3.4 metres, 2.65 g/t over 3.5 metres, 10.44 g/t over 1.50 metres and 2.15 g/t over 3.5 metres with 11 of 12 bore holes intersecting significant gold mineralization.
Mgusu
This area of historically highly active artisanal mining is defined by numerous east-west-trending, southwest-northeast-trending and southeast-northwest-trending lines of hardrock shafts that suggest that numerous mineralized structures converge and intersect in this area. These structures delineate more than 3.1 kilometres of potentially mineralized zones. Numerous, broadly scattered anomalous soil and RAB sampling gold values up to 300 parts per million (ppm) and greater further attest to the potential mineralization at Mgusu. The numerous intersecting structures present the possibility of wider low-grade mineralization due to broader deformation of the host rocks and the development of high-grade ore shoots at the intersections of principal structures.
Ngula 2
This target appears to consist of up to three poorly defined subparallel northeast-trending workings totalling approximately 900 metres in strike and possibly intersected by Bulyanhulu parallel northwest-trending structures. Shafts as deep as 30 metres and deeper with extremely high grades are reported and confirmed by this sampling with some wider areas of shallower pitting and shafts encountering lower grades.

Tembo Gold chief executive officer David Scott stated: "The widespread consistently good grades encountered in the artisanal operations are a continual encouragement and a strong confirmation of our aggressive multitarget drilling strategy. We will persist with this sampling on a routine basis as a guide to assist with target prioritization. We continue to progress with our current drill program with nine active rigs on the property and will provide drill results in significant batches with next results expected shortly."
QA/QC
(quality assurance/quality control)
A stringent QA/QC practice is being applied to all sample batches. A verified reference material standard is inserted every 20th sample, a known blank or blank standard every 20th sample and all samples with assays greater than 0.5 g/t gold (Au) are reassayed. One per cent of all samples are submitted to an alternative laboratory for check analysis. In addition the laboratory adheres to an internal QA/QC procedure including standard samples and repeats and blanks inserted independently.
The above information has been prepared under the supervision of David Scott, PrSciNat, who is designated as a qualified person with the ability and authority to verify the authenticity and validity of the data.
We seek Safe Harbor.
