Toronto, February 21, 2018 -- Canstar Resources Ltd. ("Canstar") (TSX-V: ROX), Adventus Zinc Corporation ("Adventus") (TSX-V: ADZN) and Altius Minerals Limited ("Altius") (TSX: ALS) are pleased to announce that they have entered into a three-way definitive agreement (the "Transaction") dated February 20, 2018 whereby Canstar will acquire the Newfoundland base metal exploration assets of Adventus and the Daniel's Harbour Zinc Project from Altius in exchange for: (i) the issuance of common shares of Canstar to Adventus and Altius; and (ii) a funding commitment from Altius of $500,000 as part of a $750,000 private placement (as further described below). The Transaction will allow Canstar to consolidate the majority of the Buchans Camp and adds three high quality Newfoundland zinc exploration projects to Canstar's portfolio. Upon closing of the Transaction (the "Closing"), Canstar's Newfoundland exploration team will initiate a comprehensive 2018 exploration program focused on the Buchans Camp, with a minimum 3,000 m of diamond drilling campaign anticipated in 2018 to be completed in phases (with full details of this program to follow from Canstar upon Closing).
Following the Closing, Canstar will focus its attention on polymetallic exploration in Newfoundland, in particular the Buchans Camp, where it will own the majority of the district's mineral rights. The Buchans Mine was one of the highest-grade polymetallic mines globally, producing a historical 16.2 million tonnes averaging approximately 14.50% Zn, 7.56% Pb, 1.33% Cu, 126 g/t Ag and 1.37 g/t Au over its 56-year mine life (Kirkham, 1986). The southeast corner of the region also hosted Teck Resources Limited's Duck Pond Mine, which operated between 2007 and 2015 with an initial reserve of 4.08 million tonnes averaging approximately 3.3% Cu, 5.7% Zn, 59 g/t Ag and 0.86 g/t Au (Guy Belleau & Petr Pelz, 2005). The Duck Pond 1,800 tpd flotation mill is currently on care and maintenance.

Highlights of Canstar Assets
• The Mary March Project, located 20 km east of Buchans and next to a provincial highway, which is a joint venture between Canstar (56%) and Glencore (44%).‎ Canstar has first right-of-refusal to acquire the remaining interest from Glencore; and
• In 1999 and 2000, previous owners Phelps Dodge intersected 10.33% Zn, 118.1g/t Ag, 1.62% Pb, 4.1 g/t Au, 0.66% Cu over 9.23 m; 16.8% Zn, 660 g/t Ag, 12.2 g/t Au, 5.44% Pb, 0.18% Cu over 0.91 m; and 3.02% Zn, 1.08% Pb, 72.4 g/t Ag, 0.13% Cu over 20.6 m. These remain the best drill holes in the Buchans camp, outside of the historic Buchans mine.
Highlights of Adventus' Newfoundland Assets
• Adventus is vending its 100% interest in its approximately 39,000 hectare land package located in the Buchans camp, which represents the largest land position in the camp;
• A heliborne time domain electro-magnetic (TDEM) survey flown in 2017 over the entire Buchans land package resulting in the identification of approximately 35 drill-ready targets, with some of the most exciting targets contiguous to Canstar's Mary March and Nancy April projects; and
• Adventus is also vending its 100% ownership interest in the Katie and La Poile base metal projects, both having prospective volcanic massive sulphide targets supported by historic trenching and drilling results.
Highlights of Altius' Involvement and the Daniel's Harbour Zinc Project
• ‎Altius is vending its 100% owned Daniel's Harbour Zinc Project, approximately 9,000 hectares of prospective lands surrounding the former high-grade zinc mine operated by Teck Resources Limited from 1975 to 1990. During this period, Teck reported production of approximately 7 million tonnes at an average grade of 7.8% zinc (Wardle, 2008);
• Altius and Canstar will enter into a 12-month technical services agreement with Altius to carry out the 2018 exploration program for the consolidated Newfoundland projects subject to TSX Venture Exchange ("TSX-V") approval; and
• Canstar will complete a $750,000 non-brokered private placement the proceeds of which will be applied to a first phase Newfoundland exploration program, G&A, corporate activities as well as working capital. The financing will consist of the sale of 4,166,667 common shares issued at $0.06 per share on a hard dollar basis for gross proceeds of $250,000, and 6,250,000 common shares issued on a flow-through basis at $0.08 per share for gross proceeds of $500,000. Altius is subscribing for the flow-through shares for a total investment of $500,000 and will have pro-rata equity participation rights going forward. Altius will also receive a right of first refusal on any future royalty and/or streaming financing related the Mary March property.

Dr. David Palmer, Director of Canstar, commented, "We are pleased to enter into this transaction with Adventus and Altius. Canstar has long been a champion of the Mary March Project and the consolidation of these Buchans properties into a district-scale exploration project is a great opportunity for all Shareholders. We are pleased that Adventus and Altius share our enthusiasm for its potential and with the combined technical experience of all three companies and a new management team we will be able to advance exploration programs very effectively. We look forward to completing this transaction and commencing exploration.

Christian Kargl-Simard, President and CEO of Adventus, commented, "Adventus is excited to become involved in such a prospective suite of exploration assets in one of the best jurisdictions globally to operate. This Transaction provides synergies for all three parties, and a focused vehicle to unlock the value in the Buchans Camp and Newfoundland and Labrador. We believe the timing is right to commit modern exploration in this storied Canadian base metals camp. With the local infrastructure and high grades, new discoveries will create very significant value for all shareholders."
