Rockcliff Files Updated Talbot Deposit Mineral Resource Estimate - Seite 3

The current Mineral Resource Estimate supersedes the December 2017 estimate which reported the following Inferred Resource -  4.23 Mt at 1.61% Cu, 1.40 % Zn, 1.77 g/t Au and 28.0 g/t Ag.

The main reasons for the differences between the December 2017 and current resource estimate are as follows:

• 23 additional holes drilled
• CuEq cut-off lowered to 1.5%
• ID3 grade estimation used for Au and Ag
• Attainment of suitable Indicated classification variogram.

Talbot Mineralization and Resource Expansion Potential
The Talbot Property hosts the high-grade Talbot Deposit, which is defined as a stratabound, gold-rich Volcanogenic Massive Sulphide (“VMS”) deposit consisting of coarse grain to stringer to massive sulphides of pyrite, chalcopyrite, sphalerite and pyrrhotite in a quartzofeldspathic gneiss. The polymetallic mineralization remains open at depth and to the south. The depositional environment of the Talbot Property is like that of present and past producing VMS deposits associated with bi-model volcanism (felsic to mafic volcanic and volcaniclastic rocks) in the Flin Flon – Snow Lake greenstone belt.

Quality Control and Quality Assurance
Samples of half core were packaged and shipped directly from Rockcliff’s core facility in Snow Lake to TSL Laboratories (TSL), in Saskatoon, Saskatchewan. TSL is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each bagged core sample was dried, crushed to 70% passing 10 mesh and a 250g pulp is pulverized to 95% passing 150 mesh for assaying. A 0.5g cut is taken from each pulp for base metal analyses and leached in a multi acid (total) digestion and then analyzed for copper, lead, zinc and silver by atomic absorption. Gold concentrations are determined by fire assay using a 30g charge followed by an atomic absorption finish. Samples greater than the upper detection limit (3000 ppb) are reanalyzed using fire assay gravimetric using a 1 assay ton charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity. Rockcliff has no relationship with TSL other than TSL being a service provider to the Company.
