Blackheath Resources Inc. (TSXV: BHR) (“Blackheath” or the “Company”) announces the completion of the first exploration program on the Bejanca tin / tungsten project in central northern Portugal, in which Blackheath has 100% interest.
The project area includes at least seven well-known historical mining areas and mineralization zones around the historic main Bejanca mine. The exploration initially focused on initial mapping and sampling in the surrounding historic deposits and mining operations.
Here are some analysis results of selected samples from these areas:
• 2,12% WO3 at Vale da Fonte
• 1,68% WO3 at Mina de Masgalos
• 1,00% WO3 at Mina da Bodiosa
• 0,85% WO3 at Mina de Vale Gouro
The above samples were taken at a minimum distance of one kilometer from each other. Furthermore, an 3,4 km slag sample was taken from the tailings pile next to the historic iron-tungsten melt at Mina de Vale Gouro, which had an ore content of 17,85% WO3. The amount of material is unknown. (This is a preliminary selection of samples that are not necessarily representative of the average values per zone of mineralization)
"The results of this initial exploration program at Bejanca make us very optimistic," said James Robertson, P. Eng., President & CEO of Blackheath Resources. “Bejanca wasn't just a major historic tungsten manufacturing company; Tin accounted for around 2/3 of the total metal output. We look forward to exploring the project in more detail. "
During initial exploration at Bejanca, Blackheath reviewed a historical economic assessment and resource estimate conducted by Edward D. Lynton, a mining consultant from Glendale, California in July for 1953 on behalf of the Companhia Portuguesa de Minas. The report also included a historical resource estimate of the alluvial and eluvial sand areas in the area of Bejanca and the nearby Espirito Santo deposit. It is estimated that 6.700.000 tonnes yielded 16.231 tonnes of cassiterite concentrate (tin ore) containing around 12.660 tonnes of tin, and 3.289 tonnes of tungsten ore (tungsten ore) with a tungsten trioxide content (WO3) of around 2.460 tonnes. The price of tin is currently at 21.000 $ per ton and the tungsten price is around 39.000 $ per ton of tungsten trioxide (WO3). (These estimated resources are not considered standards compliant, historical in nature, and have not been verified by the Company or its consultants, which, while relevant and used for informational purposes, are not in compliance with the current NI 43 101 Guidelines and therefore are not Reliable).
The following table shows historical resources as estimated by Lynton. These historic resources are partly covered by sand caused by the treatment of mineralized greige in the nearby Bejanca opencast mine, and have in the past been partially mined by small-scale craft businesses, but the exact extent is unknown.

Note: These estimated resources are historical in nature, are not current resources, and have not been verified by the Company or its advisors. Although they are considered relevant and are used for informational purposes, they do not comply with the current NI 43 101 guidelines and are therefore not reliable. Lynton (1953) used industry standard methods in the estimates by taking a measurement of the thickness of the alluvial bed in several pits and taking a weighted amount of the measured alluvium to determine the dry weight per tonne. To determine the degree of extraction, seven large-format samples were taken from the site; the weighed dry samples were then pulled over a shaker table. The material density was measured by the amount and weight of material taken from the pits and corrected for moisture content. The concentrates obtained from the individual sample batches were weighed after magnetic separation of cassiterite and tungstenite. This is the only known historical resource estimate. It is not part of any resource estimate category under NI 43-101 regulations.
Blackheath plans to use 2014's auger or backhoe sampling to re-evaluate the alluvial (secondary) and eluvial (primary) material at Bejanca and to further explore the potential of the hard rock and veins.
The Bejanca property is located in the northern center of Portugal, 12 km northwest of the city of Viseu, and covers an area of 89 square kilometers. The mining at Bejanca began at the beginning of the 20. Century and was continued until 1985; due to the low tungsten prices, the farms were closed. The mined material came from several mines that were operated both above and below ground near the surface. Tungsten and tin mineralization can be found both in rubble zones in old and in hydrothermal quartz veins embedded in granite rocks.
