Callinex Expands the Pine Bay East Zone and Intersects 2.3m of 9.3% Zinc Equivalent

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 31, 2016) -

Highlights:

• An 85m step-out hole from PBM-008, the initial discovery hole, intersected 2.3m of 9.3% zinc equivalent;
• A total of four holes have intersected mineralization along an approximate 175m strike length; and
• Plans to complete a deep hole testing the down-plunge extension of the Pine Bay East Zone.

Callinex Mines Inc. (the "Company" or "Callinex") (TSX VENTURE:CNX)(OTCQX:CLLXF) is pleased to announce that drill hole PBM-014, a 85m step-out hole completed to the northeast of the initial Pine Bay East discovery hole, has intersected 2.3m of 9.3% Zn Eq., containing 6.65% zinc and 0.83 g/t gold and 28.0 g/t silver. In total, four holes drilled during the 2016 Winter Drilling Campaign have outlined mineralization along an approximate 175m strike length. The main mineralization at the Pine Bay East Zone appears to be located slightly southwest and down-plunge from the Baker Patton deposit, where Callinex recently announced a near-surface drill intersection of 10.6m grading 1.4% Cu that expanded the Baker Patton deposit. The Company plans to complete at least one deep hole to test down-plunge from the Pine Bay East Zone.

Max Porterfield, President and CEO, stated, "We are encouraged by the high-grade mineralization encountered over a considerable strike length at the Pine Bay East Zone. We will complete additional drilling at depth where we can further evaluate the size potential of this new zone."

Of the four drill holes completed at the Pine Bay East Zone, holes PBM-008 and PBM-014 intersected high-grade mineralization towards the northeast while two additional holes, PBM-012 and PBM-016, completed to the southwest intersected lower grade zinc mineralization within massive sulphides. There has been almost no drilling conducted at depth, where both Placer Dome Inc. and Inmet Mining Corp. planned to explore before Callinex discovered this new zone.

Callinex has now reported results from 11 of 12 drill holes completed during the 2016 Winter Drilling Campaign. The final unreleased hole, SDB-004, was completed to expand the new zone in the Sourdough area of the Pine Bay Project that was discovered during the 2015 Summer Drilling Campaign.

Drill Results from the Pine Bay East Zone

Notes:

1. Dip and azimuth for hole PBM-012 is -75º and 275º Az. The 524m deep diamond drill hole is located at the following Universal Transverse Mercator (UTM) coordinates using the North American Datum of 1983 (NAD83) within UTM Zone 14N: 332531m East and 6071600m North. The collar of the hole is 325m above sea level.
2. Dip and azimuth for hole PBM-014 is -78º and 332º Az. The 773m deep diamond drill hole is located at the following Universal Transverse Mercator (UTM) coordinates using the North American Datum of 1983 (NAD83) within UTM Zone 14N: 332530m East and 6071600m North. The collar of the hole is 325m above sea level.
3. Dip and azimuth for hole PBM-016 is -67º and 300º Az. The 548m deep diamond drill hole is located at the following Universal Transverse Mercator (UTM) coordinates using the North American Datum of 1983 (NAD83) within UTM Zone 14N: 332586m East and 6071503m North. The collar of the hole is 322m above sea level.
4. PBM-015 was abandoned and as a result did not have any significant results.
5. PBM-013 was drilled to test a VTEM target and did not have any significant results.
6. Zinc equivalent grades are based on the following metal prices: zinc US$0.95/lb, copper US$2.55/lb, gold US$1225 per oz, silver US$16.65 per oz, lead US$0.90/lb. Metal recoveries of 100% are applied in the zinc equivalent calculation. The zinc equivalent calculation is as follows; Zn Eq = Zn grade + ((Cu grade%/100*2205 x Cu price) + (Au grade/32.15 x Au price) + (Ag grade/32.15 x Ag price))/Zn price/20).
7. True width is not currently known.

QA/QC

Individual samples were labeled, placed in plastic sample bags, and sealed. Groups of samples were then placed in security sealed bags and shipped directly to SGS Canada Inc in Vancouver, B.C. for analysis. Samples were crushed to 75% passing 2mm and pulverized to 85% passing 75 microns in order produce a 250g split. All copper, zinc and silver assays were determined by Aqua Regia digestion with a combination of ICP-MS and ICP-AES finish, with overlimits (>100 ppm Ag, >10,000 ppm Zn, and >10,000 ppm Cu) completed by fire assay with gravimetric finish (Ag) or Aqua Regia digestion with ICP-AES finish (copper and zinc). All samples were analyzed for gold by Fire Assay of a 30 gram charge by AAS, or if over 10.0 g/t were re-assayed and completed with a gravimetric finish. QA/QC included the insertion and continual monitoring of numerous standards and blanks into the sample stream at a frequency of 1 per 10 samples, and the collection of duplicate samples at random intervals within each batch at a frequency of 1 per 10 samples.

SGS Canada Inc carried out some or all of following methods to obtain the assay results for Callinex: G_LOG02 Pre-preparation processing, G_WGH79 Weighing and reporting, G_PRP89 Weigh, dry, crush, split, pulverize, G_SCRQC QC for crush and pulverize stages, G_CRU22 Crush >3kg, G_DRY11 Dry samples, GE_FAA313 @Au, FAS, AAS, 30g-5ml (Final mode), GE-IC14A Aqua Regia digestion/ICP-AES finish, GE_IMS14B Aqua Regia digestion/ICP-MS package, GE_IMS14 Aqua Regia digestion, GO_FAG303 30g, Fire assay, gravimetric finish (Au)(Final Mode), GO_FAG313 30g, Fire assay, gravimetric finish (Ag)(Final Mode) and G0_ICP13B Ore Grade, Aqua Regia digest/ICP-AES. Ag >10ppm was analyzed by ICP.

About The Pine Bay Project

The Pine Bay Project is located 16km east of HudBay's 777 Mine and processing facilities near Flin Flon, MB. The project area spans 6,000 sq. ha. and covers a significant portion of the Baker Patton Felsic Complex, one of the largest and most highly altered packages of felsic volcanic rocks within the Flin Flon Greenstone Belt. Historic exploration activities have outlined four mineral deposits, three of which are located within a mineral lease that has advanced permitting status and includes the right to conduct mining activities. The Pine Bay deposit, the largest of the four historic deposits, has a 212m vertical shaft with significant underground workings from previous exploration activities.

The project has two distinct areas with VMS mineralization, the northern Pine Bay area and the southern Sourdough area. These areas are each related to historic deposits and occur along an approximate 10km NE-SW VMS trend near the top of the Baker Patton Felsic Complex. The Sourdough area is immediately adjacent to HudBay's past-producing Centennial Mine. Callinex has recently intersected new VMS zones in both the Pine Bay and Sourdough areas.

During the 1990s, majors including Placer Dome Inc. and Inmet Mining Corp. conducted limited exploration programs in the Pine Bay area to define a large VMS deposit at depth. A review of historic work has confirmed that several proposed drill holes and targets outlined by Placer Dome there were never completed. The property position was recently consolidated for the first time combining several large claim blocks previously operated by companies including Placer Dome, Inmet, Newmont, HudBay and Cameco.

Previous to Callinex' modern geophysical and geological exploration programs, very limited work was conducted between 1996 and 2014. Callinex has digitally compiled more than 1,000 mostly shallow drill holes and has completed large airborne and ground geophysical surveys to identify and evaluate the most prospective drill targets.

Notes:
⁽¹⁾ Values have been converted from the imperial to metric system
⁽²⁾ Historical resource estimates include (a) a Cerro-Mining-Guggenheim Joint Venture report titled "Feasibility Study for 550 ton per day mine & mill", prepared by Wright Engineers Limited in 1971, reported a "geological ore reserve" 1,113,200 tons at 2.76% Cu at the Pine Bay deposit, (b) a Keys report in 1963 reported a historical resource estimate of 291,150 tons at 1.46% Cu at the Sourdough deposit, (c) a Pine Bay Mines report in 1976 reported a historical resource estimate of 125,000 tons at 0.84% Cu at the Cabin deposit and (d) a Macmillan report in 1968 reported a historical resource estimate of 95,000 tons at 0.80% Cu at the Baker Patton deposit. The historical "geological ore reserve" and resource estimates cited above is mentioned for historical purposes only and uses terminology not compliant with current reporting standards. The reliability of these historical estimates is unknown but considered relevant by the Company as it represents a significant target for future exploration work by the Company. The assumptions, parameters and methods used to calculate this historical resource estimate are not known to the Company. The qualified person has not made any attempt to re-classify the estimates accordingly to current NI 43-101 standards of disclosure or the CIM definitions. In order for these resources to be current, the Company will be required to conduct additional drilling on the Pine Bay Property. The Company is not treating this estimate as current mineral resources or mineral reserves as defined in NI 43-101. Although the Historical resource estimate was also designated as "ore" it cannot be compared to mineral reserves as it is not supported by at least a current pre-feasibility study.
⁽³⁾ Copper equivalent grades are based on metal prices of: copper US$3.00/lb, zinc $1.00/lb, gold US$1200 per oz, silver US$20 per oz. Metal recoveries of 100% are applied in the copper equivalent calculation. The copper equivalent calculation is as follows; Cu Eq = Cu grade + ((Zn grade%/100*2000 x Zn price) + (Au grade/32.15 x Au price) + (Ag grade/32.15 x Ag price)/Cu price/20).
