Foran Mining (FOM-V) confirms and expands Thunder Zone Copper-Zinc Discovery: Building a new Canadian VMS camp
March 25, '15 - NR
Follow-up drilling intersects additional massive sulphide mineralization, including 5.0% Cu, 2.1% Zn, 0.84g/t Au and 41g/t Ag over 2.62m in an ~12m thick sulphide-rich interval in BA-15-80 & 2.0% Cu, 3.5% Zn, 0.37g/t Au and 12g/t Ag over 3.46m, followed downhole by 0.7% Cu, 7.2% Zn, 0.29g/t Au and 43 g/t Ag over 3.70m within an ~15m thick sulphide-rich interval in BA-15-831
Thunder Zone open - only a portion of the anomaly has been tested
With three deposits, Hanson Lake shows potential to develop into a new VMS camp
Drilling at Bigstone underway - results in the coming weeks
Foran Mining is pleased to announce the confirmation and expansion of massive sulphide mineralization at the Thunder Zone on its 100% owned Balsam property. The Thunder Zone is located 7 km southeast of Foran's McIlvenna Bay deposit ("McIlvenna Bay") in east-central Saskatchewan, where the Company announced the results of a positive preliminary economic assessment in late 2014 (see the Foran news release dated Nov. 12, 2014).
In 2013, a single hole drilled by Foran into a newly identified geophysical anomaly hit high-grade volcanogenic massive sulphide ("VMS") mineralization in the Thunder Zone, with 4.1% Cu and 0.43 g/t Au over 3.66m, including 10.6% Cu and 0.70 g/t Au over 1.1m in BA-13-77. Drilling in the current program stepped out from BA-13-77 and cut thick intercepts of copper- and zinc-rich VMS mineralization in four of the five holes drilled, confirming a significant new blind discovery close to McIlvenna Bay. The Thunder Zone is open along strike, where drilling to date has only begun to test the extent of this deposit.
Patrick Soares, President and CEO of Foran commented "Based on Foran's exploration and discoveries of VMS mineralization around McIlvenna Bay, we believe the Hanson Lake Camp will develop into a long-lived mining camp similar to Flin Flon and Snow Lake." Soares continued "Our 2015 winter exploration program has successfully achieved its goal of expanding the Thunder Zone massive sulphide mineralization on the Balsam property. The Thunder Zone is thickening down plunge to the northwest and is open, both to the northwest and to the southeast. Drilling is underway on the historic Bigstone Deposit, 25 km to the west, with results expected in the coming weeks."

The 2015 Thunder Zone drilling followed-up 2013 drill hole BA-13-77 and continued to test a conductor plate modeled from a 2013 deep-penetrating time-domain electromagnetic geophysical ("DEEP-EM") survey.
Mineralization in holes BA-15-80 to -83 is comprised of massive to semi-massive and stringer to disseminated sulphide mineralization with various combinations of pyrite-pyrrhotite-spalerite-chalcopyrite-arsenopyrite-galena-magnetite. Alteration intensity and mineral assemblages of the host volcanic strata are similar to those at McIlvenna Bay. Significant assay intervals are summarized in Table 1 and drill hole data is presented in Table 2.

Drilling to date indicates the Thunder Zone massive sulphides strike northwest, dip approximately 35-45° to the southwest and plunge gently (approximately 7°) to the northwest. Drill indicated thicknesses of mineralization at the Thunder Zone range from approximately 4 to 15m. True thickness is interpreted to be approximately 85% of drill indicated. Mineralized intercepts start at depths of 265 to 350m below surface.
Thunder Zone massive sulphides appear to be thickening down plunge to the northwest and the zone is open in this direction. A fence of three holes drilled by Cameco in 1990 intersected strong VMS alteration and massive to disseminated and stringer-style mineralization 65m to the southeast of BA-15-80 and -82. Drill hole BA-03 intersected 10.9% Cu, 1.2% Zn, 0.75 g/t Au and 44.6 g/t Ag over 0.2m and 1.2% Cu over 1.9m. Up- and down-dip from BA-03, holes BA-05 and -06 intersected strong alteration, and intervals of disseminated to massive sulphide mineralization with low grades. The Thunder Zone remains open to the southeast beyond this fence of holes. Historic drill hole BA-07 intersected up to 2.60% Zn, 0.47% Cu, 0.82 g/t Au and 17.5 g/t Ag over 1.1m down dip from BA-13-77. Collar locations of these historic holes have been surveyed; however downhole surveys have not yet been attempted.
Program Update & Looking Ahead
Foran's winter 2015 exploration program commenced in January and includes drilling of both the Thunder Zone and the Bigstone deposit ("Bigstone"), an historic mineral resource on the Bigstone property1.
Following the completion of drilling, Foran plans to conduct borehole electromagnetic surveys on select drillholes from each of the areas drilled. A 50 line km large loop DEEP-EM survey (the same survey type that identified the Thunder Zone conductor) is scheduled for late March-early April 2015 to explore prospective stratigraphy 4 to 8 km north of McIlvenna Bay.
Drilling of the Thunder Zone is now complete, with 1,914.2m in five diamond drill holes; all assays from the Thunder Zone have now been received. Further drilling of the Thunder Zone is required to determine the extent of this deposit and management are currently evaluating next steps for follow-up work.
Drilling at Bigstone is currently ongoing, with four of six planned drill holes complete; assay results will be released once received. Bigstone drilling is being conducted with HQ diameter drill core to obtain sufficient material for initial metallurgical testwork.
Bigstone drilling is targeting an historic mineral resource located 25 km west of McIlvenna Bay. The historic mineral resource includes a copper zone with an estimated 3.75Mt grading 2.03% Cu and 0.33 g/t Au at a 1% Cu cutoff, and an adjacent zinc zone with an estimated 0.53Mt grading 9.62% Zn and 15.9 g/t Ag at a 5% Zn cutoff.
1 The historic resource at Bigstone was estimated by Cameco in 1990; Foran is not treating the historic estimate as current; a Qualified Person within the meaning of National Instrument 43-101 has not completed sufficient work to classify the historic estimate as current; additional work, including re-surveying, re-logging and drill core QA/QC would be required to verify and upgrade the historic estimate to current.
