TORONTO, ONTARIO–(Marketwired – Sept. 1, 2017) – Mezzotin Minerals Inc. (TSX VENTURE:MEZ) (“Mezzotin” or the “Company”) announced today that it has received the results of a preliminary drilling programme undertaken by Max Mind Investments (Zimbabwe) (Private) Limited (“Max Mind”) on the Company’s Sabi Star mineral claims covering approximately 2,348 hectares on the Odzi Gold Belt in the eastern part of Zimbabwe. Under a tribute agreement with the Company’s Zimbabwean subsidiary, Max Mind has the right to explore and, if warranted, mine the Company’s Sabi Star claims for tantalum and other minerals in consideration for a royalty equal to 20% of the pre-tax net profit realized by Max Mind from mining operations. The Sabi Star claims overlie a number of pegmatites within ultramafic rocks of the Mutare Greenstone Belt, which have been exploited in the past for their tantalite content.

An initial surface channel/panel sampling programme over two of the most promising pegmatites in 2010 indicated a sporadic distribution of the tantalite mineralization however, using a 250 g/t cut off, 44% of the samples returned an average grade of 508g/t of recoverable tantalite containing approximately 52% Ta2O5.

Geological mapping was completed over the area in 2015 and subsequent to this work 12 trenches were sampled at 1-m intervals and analyzed, which confirmed the irregular zonation of the pegmatites and sporadic distribution of the tantalite. Nevertheless, the results suggested that there could be coherent zones of exploitable mineralization and Max Mind undertook the 10-hole drill programme listed in Table 1 and shown on the plan in Figure 1.

The trench analyses focussed on tantalum, niobium, titanium, tungsten and tin and the tantalo-columbite intercepts formed the targets for the HQ core drilling. Two lines 200 m apart on each of the two pegmatites were selected with inclined holes spaced at approximate 100-m intervals along the lines and depths planned at around 70 m.

These were completed between April and June 2016. Some holes had to be re-collared because of bad ground and only seven holes produced core of sufficient quality to be logged, split, sampled and sent to the accredited SGS laboratory in Johannesburg, South Africa. The three other holes were logged but not sampled.

Only the pegmatite intercepts were sampled and these at 1-m intervals. On Pegmatite 1 (See Figure 1) a total of 335.61 m were drilled and the average inclined pegmatite width was 39.09 m. A total of 195.66 m were drilled on Pegmatite 2 and the average pegmatite intercept width was 6.87 m.

The geological and structural core logging indicates that both pegmatites have irregular outlines with moderate to steep dips to the north and northwest.

The core splitting and sampling was done on site with half being taken as a sample and the other half retained for reference. Each sample despatched weighed approximately 3 kg and a total of 258 samples, including Certified Reference Materials (CRMs) and duplicates, were sent to SGS for analysis of Tantalum, Beryllium, Niobium, Germanium, Tin, Rubidium, Lithium, Tungsten, Caesium and Titanium.

All analytical receipts were checked for quality through the CRMs and the few batches that were not acceptable were sent for re-analysis. The Harare office of SRK Consulting has approved the quality aspects of the analytical work.

The drilling results show that the tantalum and lithium intercepts are not coincident and this is confirmed by correlation statistics between the two elements. The analytical results of this drilling programme are similar to those obtained from earlier sampling. Also confirmed are the positive grades from some of the mineralized zones, which indicate that further, closely spaced drilling is required. However, while the analyses indicate that the Sabi Star pegmatites have potential to be economically mined, the drill spacing of approximately 200 by 100 m is far too wide to allow any of the mineralization to be categorized as a mineral resource and additional infill drilling will be required on perhaps a 25 by 25 m grid.

The tables below show the intercepts for each borehole. These record the best intercepts for either Ta2O5 or Li2O or both where the higher values do correspond. Beryllium and Titanium are not reported because of their very low grades.
