Callinex Announces Results from the 2018 Drilling Campaign

 

 

 

 

 

Callinex Mines Inc. (TSX-V: CNX) (OTCQX: CLLXF) is pleased to announce results from the 2018 drilling campaign at the Company’s 100% owned Nash Creek Project located within the Bathurst Mining District of New Brunswick (See Figures 1 and 2). The majority of drill holes were completed to test sparsely drilled areas periphery to the Nash Creek Deposit and two holes were drilled to test a preliminary induced polarization target to the east (See Table 1 and News Release dated July 11, 2018). Most of the holes drilled to the north targeted an untested portion of a 3 km long soil anomaly and did not encounter significant mineralization. The two widely-spaced holes drilled into the Central Zone target intersected mineralization ranging up to semi-massive sulphides with zinc and lead values (See Table 1).

 

Two widely-spaced drill holes, NC18-301 and NC18-302, tested part of the Central Zone target that was identified late in the 2018 field season. Results from these two drill holes has revealed lithologies, alteration, and mineralization which replicates an environment similar to the Hickey Zone, located 1.2 km to the west. This Central Zone target was identified within a small area that was covered as part of a much larger 175 line km IP survey that was previously announced (See News Release dated October 1, 2018). The district-scale IP survey is still ongoing and anticipated to be completed in the first quarter of 2019.

 

A 2019 drilling campaign is anticipated to follow-up on targets generated from the IP survey including additional drilling on the Central Zone target that spans 1900m x 400m and is located 1 km east of the Nash Creek Deposit. Nearly all volcanogenic massive sulphide deposits occur in clusters and the Nash Creek deposit is the only deposit along this 20 km trend. To date, very limited exploration has been completed within the Nash Creek land package that encompasses several high-grade mineral occurrences and has potential to host other deposits.

 

These results have confirmed that IP is the most effective method to directly target near-surface mineralization at the Project. The ability of the IP survey to accurately vector towards increased sulphide mineralization, which generally correlates with higher grade mineralization at the Nash Creek Deposit, is very encouraging to apply on the 150 km2 district-scale land package.

 

Additionally, the drilling campaign identified mineralization west and east of the Hickey Zone with drill holes NC18-281 intersecting 3.0m of 10.9% Zn, 1.2% Pb and 23.3 g/t Ag along with NC18-293 intersecting 9.0m of 2.3% Zn, 0.4% Pb and 5.9 g/t Ag (See Table 1 and Figure 2). Mineralization was also encountered to the northwest of the Hayes Zone. These results confirm the potential to expand the deposit further with step-out drilling in the future.

 

Drill hole NC17-289 completed 475m to the north of the Hickey Zone intersected 8.0m of 1.8% Zn, 0.3% Pb, and 3.4 g/t Ag. The depth of mineralization intersected indicates that the stratigraphy plunges to the north and any future exploration in this area would be focused on targeting mineralization that could be amenable to underground mining. Drilling completed along a 3 km long soil anomaly to the northwest did not encounter significant mineralization, unlike it had previously along the southern 2 km where it was coincident with an IP response.

 

The Company’s overall exploration activities since mid-2017 have yielded positive results that contributed to an increase in Indicated zinc equivalent pounds by 74%, to 963 million pounds, and Inferred zinc equivalent pounds have increased by 385%, to 407 million pounds since the Project was acquired in 2016 (See Table 2 and News Release dated April 16, 2018).

 

The maiden 2018 PEA outlined a high-margin, open-pit mine plan that generates a pre-tax internal rate of return of 34.1% and Net Present Value at an 8% discount rate of $230 million based on a zinc price of US $1.25 (See News Release dated May 14, 2018). The life of mine all-in sustaining costs (“AISC”) were estimated at approximately US $0.28 per pound of zinc produced, net of by-product credits (See News Release dated May 14, 2018).

 

Cautionary Note on PEA. The PEA is preliminary in nature and it includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the PEA will be realized.

 

J.J. O’Donnell, P.Geo, a qualified person under National Instrument 43-101 and a Consultant for Callinex, has reviewed and approved the technical information in this news release.

 

 

Acquisition of Headway Property

Callinex is also pleased to announce that it has acquired a 100% interest in the Headway Property, located in the Bathurst Mining District, New Brunswick. In consideration of the Headway Property, Callinex issued a total of 250,000 common shares to the vendor.  The details of the transaction are set forth in the news release dated November 14, 2018.

(1)       Callinex reported closing the acquisition of the Nash Creek Property on August 15, 2016.  The effective date of the “Pre-Acquisition” mineral resource estimate is March 27, 2009, the effective date of the “Post-Acquisition” mineral resource estimate is March 21, 2018.  The 2009 mineral resource is considered to be historical and has been superseded by the mineral resource estimate with effective date March 21, 2018.
(2) Classification conforms to NI 43-101, Companion Policy 43-101CP, and the Canadian Institution of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards on Mineral Resources and Mineral Reserves adopted by CIM council, as amended. Inferred Resources have been estimated from geological evidence and limited sampling and must be treated with a lower level of confidence than Measured and Indicated Resources.
(3) Pre-acquisition zinc equivalency (ZnEq) was calculated as Zn% + 0.633*Pb% + 0.008*Ag_ppm, the Post-Acquisition zinc equivalency is calculated as Zn%+ 0.747*Pb% + 0.006*Ag_ppm.
(4)  The Post-Acquisition estimate is reported using a 1.5% ZnEq cut-off value, which is reduced from a 2% ZnEq cut-off that was used to report the Pre-Acquisition estimate.
(5) A bulk density value of 2.76 was used in the Pre-Acquisition estimate, and bulk density was calculated based on relationship to grade for the Post-Acquisition estimate using the formula 2.74+0.028*(Zn%+Pb%).
(6) Tonnes and ZnEq contained pounds are rounded.

 

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 Garson, Ontario for preparation and then onto Burnaby, BC for analysis. Samples were crushed to 75% passing 2mm and pulverized to 85% passing 75 microns in order to produce a 250g split. All copper, zinc and silver assays were determined by Aqua Regia (2 and 4 acid) digestion with a ICP-AES finish, with overlimits (>100 ppm Ag, >10,000 ppm Zn, and >10,000 ppm Cu) Aqua Regia digestion with ICP-AES “ore-grade” 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 the following methods to obtain the assay results for Callinex: G_LOG02 Pre-preparation processing,G_PRP89 Weigh, Dry, to 3kg, Crush 75% -2mm, Split to 250g, Pulverize to 85% -75┬Ám, GE-ICP14B two acid digest for non-organic, or low sulphides, GE-ICP40B four acid digest AES 33 element package, GO-ICP13B, ore grade Aqua Regia Digest with ICP/AES finish, GO-ICP41Q ore grade Aqua Regia Digest ICP/AES finish.
