Nuinsco Resources Limited: CBay's Devlin Copper Deposit in Chibougamau Provides Impressive Copper Grades

Drilling intersections demonstrate good grade and continuity for resource delineation

TORONTO, ONTARIO--(Marketwired - Dec 16, 2014) - Nuinsco Resources Ltd. ("Nuinsco" or "the Company") (TSX:NWI) (www.nuinsco.ca) today announced receipt of analytical results from its diamond drilling program at the Devlin copper project, Chibougamau, central Quebec. Results from the first six include copper grades of up to 8.57% Cu over 1.0m and 11.0% Cu over 0.5m.

Devlin is held by CBay Minerals Inc. ("CBay). The object of the program is to develop a resource estimate on the project which will supplement the NI 43-101 copper resource that already exists on the nearby, 100% CBay-owned, Corner Bay deposit. Both Devlin and Corner Bay have the potential to provide feed to CBay's Copper Rand mill in Chibougamau following a short period of additional development. The Company believes that the drill program and resource development at Devlin is the most effective method of adding value to the Chibougamau assets and hence to shareholders.

Thirteen vertical diamond drill holes were collared and completed at the deposit, comprising 1,461m of drilling in total. The intent of the drill holes was to obtain intersections to characterize the sulphide mineralization and to better define its limits. The results from these holes will be combined with those from earlier programs to provide sufficient ore grade intersections to produce a resource estimate. The results of DDHs DEV-14-01 through DEV-14-06 are reported here. Intersections of copper mineralization are consistent with historical results and demonstrate good continuity of grade. Of particular note is the intersection from DDH DEV-14-01 of 2.2m grading 4.33% Cu (true width) and DEV-14-03 with 9.5m grading 1.25% Cu (true width) and 3.0m grading 2.88% Cu (true width).

All intersections are true width. '--- Insufficient data to calculate average'

Devlin is an easily accessible, partially-developed, high-grade copper deposit located about 10km west of Corner Bay and about 40km by road from the Copper Rand mill and tailings management facility. Both Devlin and Corner Bay are directly accessible via the local road network.

As currently identified, the mineralized zone at Devlin is 365m long, 215m wide, approximately 1.8m thick on average and is accessed by a 350m decline and over 600m of exploration drifts. In 1982, a bulk sample of 16,330 tonnes grading 3.72% copper was processed at a mill in Chibougamau with recoveries reported in the mid-90% range. In 1995, Watts Griffiths and McOuat Limited ("WGM") estimated Devlin to contain Proven and Probable reserves of 146,000 tonnes at 3.38% copper, Measured and Indicated resources of 149,700 tonnes grading 3.95% copper and Inferred resources of 90,700 tonnes grading 3.69% copper (historic results reported by WGM in 1995, see below for disclosure regarding this estimate). The Devlin deposit is within 100m of surface.

The Qualified Person, as defined under National Instrument 43-101, is Julie Bossé, P.Geo. (OGQ) who has reviewed and approved the technical content presented here.

Disclosure of Historical Devlin Project Resource/Reserve Estimate

In 1995 Watts Griffiths and McOuat (WGM) reported a resource/reserve estimate on the Devlin deposit. The resource incorporated all data available at the time pertaining to mineralization at Devlin and employed both surface and underground information. WGM employed the polygonal method to determine the resource, used a minimum vertical thickness of 1.83m in the mineralized domain and incorporated dilution to attain 1.83m if a given intersection was less than that thickness. A cut-off grade of 2.5% copper and a density of 2.78/cm³ was employed. The historical estimate included Measured, Indicated and Inferred resources and Proven and Probable reserves as defined in the Australasian Code for Reporting Mineral Resources. Proven and Probable reserves were derived from the Measured and Indicated resources by adding additional dilution and applying an 85% mine recovery factor. No more recent resource estimates have been conducted. In order to update the WGM estimate to current standards additional diamond drilling will be necessary to confirm historical results. A Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources; the issuer is not treating the historical estimate as current mineral resources.

Analytical Methods and QA/QC Procedure

Samples were both saw-cut and hydraulically split under the supervision of the Quebec licensed project geologist, with half the core returned to the core box for future reference. Samples were then securely sealed along with sample number tags in bags stored under lock and key at the Copper Rand mine site core shack facility, until delivered to the analytical laboratory operated in Val d'Or by ALS Minerals.

Certified reference standard materials sourced from Canadian Resource Laboratories Ltd., and barren "blank" samples will be inserted systematically into the sample sequence in order to monitor the results reported by the assayer for quality assurance and quality control purposes. Results from the QA/QC samples were reviewed by a qualified independent geochemist prior to public release to ensure that results reported conform to industry best practice standards.

Copper concentrations were determined with the ALS Minerals ME-ICP41a analytical package, an aqua regia dissolution of a portion of the sample pulp with induced coupled plasma or atomic emission spectroscopy finish. Over-limit results of >5% copper were re-run automatically with the more rigorous AA-46 Ore Grade method utilizing a four acid digestion to determine precise concentrations. Gold analyses were performed on selective samples by means of 30g fire assay employing an atomic absorption finish.

Tailings Management Area Improvements Completed

In addition, the previously-announced work has been completed at the CBay tailings management areas (TMA) in order to upgrade the facilities for future use (see news release dated October 17, 2014). The construction works included the installation of an operational and emergency spillway and dam raise. The dam raise included installation of a clay core, rip protection and surface cover. The implementation of this work helps to position CBay for any future resumption of production from its properties and/or to take advantage of any custom milling opportunities that arise. The work was completed on time and on budget.
