Lagoa Salgada LS-1 Resource Expansion Program - Hole LS-MS-03 Strikes 13.0m Of 12.42%1 Zinc Equivalent; Discovery Of New Mineralized Zone grading 1.24% Copper
HIGHLIGHTS:
- LS-MS-03 drill hole strikes 131m of 0.49% copper, including 20m of 1.24% copper
- Copper grades more than double to 1.24% at depth (231m)
- Massive sulphide zone of 28.0m grading 8.85% zinc equiv1., including 13m of 12.42% zinc equiv.1
- LS-MS-03's new stockwork zone is copper rich, could be economic without by-product credits
- First three holes of resource expansion program strike larger zones, along with higher grades.
George Town, Cayman Island - August 15, 2017 - Mineral & Financial Investments is very pleased to announce its 49%-owned investment, TH Crestgate GmbH, a private Swiss-based investment company has released the third set of assay results from its new drilling campaign designed to try to expand the LS-1 resource at the 100%-owned Lagoa Salgada zinc-copper project in southern Portugal.
The holes were completed by wholly-owned local subsidiary, Redcorp Empreedimentos Lda. The current resource is 4.5Mt, with a zinc equivalent grade of 8.2% (see RNS of August 27, 2015). This drill program, announced and initiated in June 2017, is focussed on expanding the existing LS-1 Resource. The current resource is 4.5Mt, with a zinc equivalent grade of 8.2%. This drilling program is targeting expanding the resource by 75%-to-125% to between 8.0Mt and 10.0Mt, although at this stage there can be no guarantee that can be achieved.

The third hole of a six-hole program being undertaken by TH Crestgate has just returned with assays. LS-MS-03 is a 70° drill hole located in the northern half of the current resource 50m to the south of the first hole, LS-MS-02. This angled hole intercepted mineralization 50m above where mineralization was previously thought to begin. The LS-MS-03 drill hole is mineralized from a depth of 147m (where the assaying began) to the bottom of the hole at 331m. The hole intercepted 28m of massive sulphides in what had been an unknown area of mineralization. This intercept carries an average grade of 8.85% zinc equivalent1, which is slightly above the historical preliminary resource grade of 8.2%. This interval also indicated that the mineralization is open to the east and down dip. Copper grades more than double to 1.24% at depth (231m). These grades would be very likely economic to mine without any by-product credits from any other mineralization.
Jacques Vaillancourt, Chairman of Mineral and Financial, commented: "This third hole expands the dimensions and tonnage of the mineralized zone and continues to validate our belief that the resource can be significantly expanded from its historical size of 4.5Mt. This third hole follows on from the highly encouraging first and second holes. Additionally, it demonstrates that the stockwork mineralization, in the stringer zones, likely has sufficient copper to be economic on its copper content alone. This new copper rich stringer zone is found in the ore bodies supporting the both the Neves Corvo and Aljustrel mines located nearby on the Iberian Pyrite Belt."

The LS-1 resource expansion drill program of 6 angled holes will additionally help define the true width of the mineralization. Based on cost estimates provided by TH Crestgate to Mineral & Financial, the Company has adequate resources to provide support for this programme.

Asset Description
The Lagoa Salgada resource is centred on one gravimetric anomaly called LS-1. There are a total of 17 gravimetric anomalies on the property. These anomalies remain to be fully tested. A petrographic study undertaken by TH Crestgate focused on the LS-1 area of the Lagoa Salgada property and also indicated the presence of anomalously high levels of indium in sphalaritic (zinc-rich) zones of mineralization. The orebody is composed of a central stock work zone - a more than 700m thick volcano-sedimentary complex - and a massive sulphide lens in the northwest. It is covered by more than one hundred meters of sediments of the Sado Tertiary basin.
The historical, Canadian Institute of Mining (CIM) compliant, resource estimate, located on LS-1, completed in 2012 by Paul Daigle, P.Geo, is summarized below:
