    Dublin, 02 December, 2015 – Minco Plc (AIM-“MIO”) (“Minco” or the “Company”) is pleased to announce that, through its wholly owned subsidiary Buchans Minerals Corporation (“Buchans Minerals), it has entered into a collaboration agreement with Canadian Zinc Corporation (TSX: CZN; OTCQB: CZICF) (“Canadian Zinc”) to undertake a research program to complete physical and metallurgical bench scale studies on seven volcanogenic massive sulphide (“VMS”) deposits located in central Newfoundland and to share research data on their respective central Newfoundland Cu-Pb-Zn-Ag-Ag deposits.

    The total cost of the research project is estimated at $735,000 with Buchans Minerals and Canadian Zinc each contributing up to $100,000. The Research & Development Corporation of Newfoundland and Labrador (“RDC”) is providing Canadian Zinc funding of $535,000 for the research project through the GeoEXPLORE Industry-led R & D Technology Development and Demonstration Program.

    The intent and objective of the program is to determine the technical and economic viability of developing the companies’ key deposits into producing operations by utilizing a central milling facility. The concept is based on the potential that collectively, the satellite deposits can be economically mined, preconcentrated, trucked and then milled simultaneously or sequentially through a central mill.

    The collaboration agreement between Buchans Minerals and Canadian Zinc is focused on seven VMS deposits located in central Newfoundland. Four of the deposits are held by Canadian Zinc (Lemarchant, Boomerang-Domino, Tulks East, and Long Lake) and three of the deposits are held by Buchans Minerals (Bobbys Pond, Daniels Pond and Tulks Hill).

    The seven deposits have all demonstrated resources of various sizes and quality and all are located near the communities of Millertown and Buchans, NL and all within trucking distance (30-90 km) of the recently closed Duck Pond Cu-Zn Mine. Individually at this time, the various deposits are not large enough to support stand-alone operations, but could potentially be developed with improving economic factors and by utilizing a central mill facility.

    Outcomes of the research project will provide key information on which to further evaluate the economic viability of developing the central Newfoundland deposits through a central milling facility. Positive results would lead to continued development work on the known deposits, renewed exploration interest leading to new discoveries, and ultimately, ongoing mining operations in central Newfoundland.

    Thibault & Associates Inc., an applied process chemical engineering firm located in Fredericton, NB, has been awarded the contract to complete bench scale physical/metallurgical studies and the process simulation and cost modelling.

    As a part of the collaboration agreement, both Companies have undertaken to complete physical and metallurgical bench scale studies on the deposits in order to:

    1. assess the amenability of mineralized samples from the deposits to physical upgrading (preconcentration) at site by Dense Media Separation as a potential means of reducing transportation costs of the mineralized material from site to the milling facility and to maximize head grade for reduction in downstream processing cost;
    2. assess the amenability of mineralized samples from 4 of the 7 deposits to a common flotation flowsheet for the production of selective copper, lead, and zinc concentrate products of marketable grade at acceptable metallurgical recoveries. This will serve as a preliminary evaluation of whether or not a single flowsheet and reagent scheme could be used for processing multiple resources at a central mill. The deposits to be included are Boomerang-Domino, Bobbys Pond, Daniels Pond and Lemarchant; and
    3. determine the levels of deleterious elements present in the four deposits and in the flotation concentrates produced, as well as determining the acid generating potential of the four deposits and from the flotation tailings generated.


    The bench scale testing program will be followed-up by the development of a process simulation and cost assessment model to evaluate and identify the key factors controlling the earning potential of a centralized milling concept for processing of the satellite base metal deposits. Results from the modelling will be used to help optimize the exploration and development budgets, by focusing on the key factors that are critical to realizing the economic potential of the base metal deposits in central Newfoundland.

    The Buchans area of central Newfoundland is one of Canada’s richest, historic base metal mining camps. Between 1928 and 1984 Asarco mined 16.2 million tonnes of ore at Buchans averaging 14.51% Zn, 1.33% Cu, 7.56% Pb, 126 g/t Ag & 1.37 g/t Au from a series of in situ massive sulphide and transported breccia sulphide deposits. Between 2007 and 2015 Teck Resources Limited milled 5.0 million tonnes averaging 4.4% Zn, 2.8% Cu, 53 g/t Ag & 0.6 g/t Au from its Duck Pond Mine.

    Canadian Zinc is a TSX-listed exploration and development company trading under the symbol “CZN”. The Company’s key project is the 100%-owned Prairie Creek Project, a fully permitted, advanced-staged zinclead-silver property, located in the Northwest Territories.

    Canadian Zinc also owns an extensive land package in central Newfoundland that it is exploring for copperlead-zinc-silver-gold deposits, including three VMS projects, each with defined deposits, which are being explored by Canadian Zinc. Key deposits on each project are listed below:

    South Tally Pond Project – Lemarchant deposit; Indicated Mineral Resource of 1.24 million tonnes grading 5.4% zinc, 0.5% copper, 1.2% lead, 1.0 g/t gold and 59.27 g/t silver plus an additional Inferred Mineral Resource of 1.34 million tonnes grading 3.7% zinc, 0.4% copper, 0.9% lead, 1.0 g/t gold and 50.4 g/t silver (Giroux Consultants 2012);

    Tulks South Project – Boomerang-Domino deposit: Indicated Mineral Resource of 1.36 million tonnes grading 7.1% zinc, 3.0% lead, 0.5% copper, 110 g/t silver and 1.7 g/t gold plus an additional Inferred Mineral Resource of 0.69 million tonnes grading 6.5% zinc, 2.8% lead, 0.4% copper, 95 g/t silver and 1.0 g/t gold (Snowden 2007); and the Hurricane and Tulks East prospects; and

    Long Lake Project – Indicated Mineral Resource of 0.48 million tonnes grading 7.8% zinc, 1.6% lead, 0.97% copper, 49 g/t silver and 0.57 g/t gold plus an additional Inferred Mineral Resource of 78,000 tonnes grading 5.7% zinc, 1.2% lead, 0.7% copper, 34 g/t silver and 0.48 g/t gold (SRK, 2012).

    Canadian Zinc’s exploration strategy in Newfoundland is to continue to build on its existing polymetallic resource base with the aim of developing either a stand-alone mine, similar to the past-producing mine at Buchans or the Duck Pond mine, or a number of smaller deposits that could be developed simultaneously and processed in a central milling facility.
