Callinex Intersects Extensive Near-Surface Zinc Mineralization at Nash Creek in New Brunswick
Highlights
- Drill Hole NC-249, the northernmost hole, intersected extensive mineralization including 53.8m of 2.8% Zn Eq. starting at a depth of 18.5m including higher grade intervals;
- These drill four holes have expanded the lateral extent of the northernmost area of the Nash Creek Deposit up to 260m; and
- 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.
VANCOUVER, Jan. 22, 2018 /CNW/ - 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). Three of these four drill holes expanded the Nash Creek Deposit to the northwest of recently reported drill holes NC17-248, NC17-255, NC17-257 and NC17-269 (See News Release dated January 18, 2018). Drill Hole NC-249, the northernmost hole, intersected extensive mineralization including 53.8m of 2.8% Zn Eq. starting at a depth of 18.5m including two separate higher-grade intervals of 11.5m of 5.1% Zn Eq. and 10.7m of 4.0% Zn Eq. within 60m of surface (See Figures 4 and 5). These drill holes have expanded the lateral extent of the northernmost area of the Nash Creek Deposit up to 260m (See Figure 2 and 3).
Highlights from these drill holes include:
- Hole NC17-246 intersected 12.0m of 3.9% Zn Eq. from a starting depth of 44.1m including 8.4m of 5.3% Zn Eq. along with a separate intersection of 3.3m grading 4.4% Zn Eq. at a starting depth of 84.7m;
- Hole NC17-247 intersected 7.0m of 1.9% Zn Eq. at a starting depth of 82.0m including 1.0m of 6.1% Zn Eq.; and
- Hole NC17-249 intersected 53.8m of 2.8% Zn Eq. including 11.5m of 5.1% Zn Eq. at a starting depth of 18.5m including 11.5m of 5.1% Zn Eq. and 10.7m of 4.0% Zn Eq.
Max Porterfield, President and CEO, stated, "The impressive width of mineralization intersected indicates potential to build additional tonnage in the northern expansion of the Nash Creek Deposit. Furthermore, the depth of this mineralization combined with higher grade zones could add significant value to the upcoming PEA."
Callinex plans to delineate the extent of the Nash Creek Deposit along strike in both directions that is coincident with a 3 km long zinc-lead soil anomaly, of which only the southern 2 km has been drilled. 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).
Jason Levers, P.Geo, a qualified person under National Instrument 43-101 and Project Geologist for Callinex, has reviewed and approved the technical information in this news release.

1. |
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). |

All intervals are reported as core width drilled thicknesses; true thicknesses are estimated to be 80-100% of drilled thicknesses. |

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. |

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), G0_ICP13B Ore Grade, Aqua Regia digest/ICP-AES. Ag >10ppm was analyzed by ICP and GO_XRF77B-pyrosulfate fusion.
