- Drill hole NC17-257 returned exceptional near-surface results with a 15.0m intersection grading 7.2% Zn Eq. including 9.0m of 11.1% Zn Eq. from a starting depth of 113.0m;
- Hole NC17-255 intersected 21.0m of 2.8% Zn Eq. including 9.0m of 5.5% Zn Eq. at a starting depth of 118.0m; and

Vancouver, British Columbia – January 18, 2018 – Callinex Mines Inc. (the “Company” or “Callinex”) (TSX-V: CNX; OTCQX: CLLXF) is pleased to announce assay results from four drill holes as part of the recently completed 35 drill hole campaign at the Company’s 100% owned Nash Creek Deposit located within the Bathurst Mining District of New Brunswick (See Figures 1, 2 and 3). Drill hole NC17-257 returned exceptional near-surface results with a 15.0m intersection grading 7.2% zinc equivalent (“Zn Eq.”) mineralization including 9.0m of 11.1% Zn Eq. from a starting depth of 113.0m (See Table 1). These four holes have expanded the Nash Creek Deposit an additional 180m to the north of the initial 2017 summer drilling campaign, and 600m north of the mineral resource (See Figure 4). The deposit remains open for expansion to the north and south.
Highlights from these four drill holes include:
- Hole NC17-248 intersected 13.0m of 2.5% Zn Eq. including 4.6m of 4.5% Zn Eq. at a starting depth of 82.0m;
- Hole NC17-255 intersected 21.0m of 2.8% Zn Eq. including 9.0m of 5.5% Zn Eq. at a starting depth of 118.0m;
- Hole NC17-257 intersected 15.0m of 7.2% Zn Eq. including 9.0m of 11.1% Zn Eq. at a starting depth of 113.0m; and
- Hole NC17-269 intersected 7.0m of 3.2% Zn Eq. including 3.0m of 6.6% Zn Eq. at a starting depth of 108.5m.
Max Porterfield, President and CEO, stated, “Our success in expanding the strike length of the deposit by nearly 50% over the last six months of exploration speaks to the exciting potential of the project. While we continue to focus on exploration advances in 2018, we are eager to publish an updated resource and maiden Preliminary Economic Assessment for the Nash Creek Deposit in the coming months. We are targeting the PEA to have a base-case scenario of a standalone open pit operation with potential to process between 15 to 20 million tonnes of material.
Callinex plans to delineate the extent of the Nash Creek Deposit along strike in both directions along a 3 km long zinc-lead soil anomaly, of which only the southern 2 km has been drilled and is coincident with the Nash Creek Deposit. The Company also plans to test satellite zones that are open for expansion and commence a district-scale exploration program along the 20 km long land package.
The Nash Creek Deposit hosts a near surface indicated resource totaling 712 million pounds Zn. Eq. and inferred resource totaling 88 million pounds of Zn Eq. (See Table 2). The Company’s Superjack hosts an additional near-surface inferred resource totaling 328 million pounds of Zn Eq. in the Bathurst Mining District (See Table 2).
The Project benefits from tremendous infrastructure within close proximity. The Nash Creek Deposit is located approximately 1 km from Provincial Highway 11, high-voltage transmission lines and only 25 km by road to Glencore’s Brunswick Smelter, deep water port, railway and power plant near the town of Belledune (See Figures 1 and 2). Callinex is currently working towards publishing an updated resource estimate and maiden Preliminary Economic Assessment (“PEA”).
The PEA is expected to have a base-case scenario of a standalone open pit operation with potential to process between 15 to 20 million tonnes of material using dense media separation (“DMS”) as a pre-concentration process before the material would be delivered to a conventional flotation mill.
Metallurgical test work indicates the Nash Creek Deposit is amenable to conventional flotation techniques with recoveries of 91% for zinc and 82% for lead based on a coarse grind size. Additional tests also indicate that the current resource grade could be upgraded with the use of dense media separation to a head grade of 5-7% Zn Eq. (See News Release dated September 12, 2016).
Mineralization at the Nash Creek Deposit is hosted in both felsic and mafic units, with porosity and structure (specifically faults/fracture zones) being the key features that control the extent and distribution of the mineralization. Zinc mineralization is hosted in a low iron sphalerite that is difficult to visually estimate and lead mineralization is hosted in galena. The mineralized envelopes (lenses) are sub-horizontal and appear to cross-cut the shallow east dipping stratigraphy.
Drilling in the northeastern area has indicated that the stratigraphy appears to dip more steeply towards the northeast portion of the deposit than other areas. Also, this area appears to have a significantly higher ratio of zinc relative to lead and silver as compared to other portions of the deposit.

- Zinc equivalent grades are based on the following metal prices: zinc US$2,525/t (1.15/lb), lead US$2,205/t (1.00/lb), and silver US$18.0 per oz. Metal recoveries of 100% were applied in the metal equivalent calculations. The zinc equivalent calculation is as follows: ZnEq = 100 ((Ag Price in (g) x Ag Grade) + (Pb Price*2204.6 x Pb Grade(%)/100) + (Zn Price*2204.6 x (Zn Grade(%)/100))/Zn Price*2204.6).
- The numbers may not add due to rounding.
- True widths are not currently known.

- Resources are categorized according to CIM Definition Standards; it cannot be assumed that all or any part of Inferred Mineral Resources will be upgraded to Indicated or Measured as a result of continued exploration.
- The Nash Creek mineral resource estimate includes the Hickey Zone and Hayes Zone.
- The Superjack mineral resource estimates includes the Nepisiguit A (the “A Zone”) and Nepisiguit C Zones (the “C Zone”).
- Zinc equivalent resources for the Nash Creek Project were calculated using metal prices of $0.90/lb for zinc, $0.87/lb for lead, and $17.73/oz for silver. Metallurgical recoveries have been assumed to be 90.5% for zinc, 81.5% for lead and 50% for silver. A cut-off grade of 2.0% Zn Eq. was utilized in the resource estimate.
- Zinc equivalent resources for the Superjack Project were calculated using metal prices of $1.12/lb for zinc, $1.06/lb for lead, $2.97/lb for copper and $20.38/oz for silver. Metal recoveries have been assumed to be 100% for zinc, 72% for lead, 86% for copper and 70% for silver. A cut-off grade of 1.5% Zn Eq. was utilized in the resource estimate.

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.
