MONTRÉAL, QUÉBEC–(Marketwired – Dec. 7, 2017) –

NOT FOR DISTRIBUTION IN THE UNITED STATES OR TO U.S. NEWSWIRE SERVICES

Goldstar Minerals Inc. (“Goldstar” or the “Company”) (TSX VENTURE:GDM) is pleased to announce that it has received results from the initial reconnaissance prospecting at its Victoria Lake Property, located in New Brunswick, Canada.

The Victoria Lake Tin Property extends East-West over a distance of nearly 20 kilometres from the Mount Pleasant area to the southeast of Victoria Lake. The property immediately borders to the south the former Mount Pleasant tungsten and molybdenum mine owned by Adex Mining Inc. which has published a National Instrument 43-101 indicated resource of 12.4 million tonnes at 0.38% tin (Sn), 0.86% zinc (Zn) and 64 ppm indium (In). Access to the property remains excellent all year round and is close to infrastructure.

The prospecting was following up some of the numerous historical and previously identified tin occurrences in the eastern region of the property. Highlights of the prospecting are detailed below.

Samples returned tin and silver at surface.

A total of 5 samples were collected within an area roughly 1.5 km by 1.5 km from highly altered granitic rocks, often designated as greisens.

Of note, the sample E6648188 that yielded low tin is characterized by a relatively high sulfide content (3-5%) which can be useful as a discriminant tool for geophysical surveys.

Assays were performed at AGAT Laboratories located in Mississauga, Ontario using peroxide fusion and ICP finish. These are grab samples that are not necessarily representative of the mineralization hosted on the property. Due to the small number of samples, no standards, blanks or duplicates were inserted.

Next steps

The exploration team will prepare and design a detailed prospecting program, including airborne surveys, for the summer of 2018. The Company is aiming to start a modest reconnaissance drilling program in early 2019 that will investigate potential mineralized systems. Access for drilling is excellent all year long and easy logistics are expected.

Benoit Moreau, President and CEO of Goldstar comments: “The Victoria Lake Project is still in the early stages and we are very pleased to confirm outcrops with grades similar to already identified tin occurrences. The upcoming detailed geophysics and prospecting in 2018 will allow for a more complete understanding of the mineralization and how it relates to regional structures. At the present time the exploration team continues to be focused on the upcoming drilling campaign at the Lake George project where we have identified significant gold bearing structures from outcrops including the WLF zone which averages 1.0 g/t Au over an area 100m x 25m.”
