Vanstar Update on the Nelligan Project in Quebec

LA PRAIRIE, QUÉBEC--(Marketwired - May 26, 2015) - The management of Vanstar Mining Resources (TSX VENTURE:VSR) wishes to make an update of the exploration program currently being conducted by its partner IAMGOLD Corporation (IAMGOLD), on the Nelligan Project, located in the Chibougamau-Chapais region in Northwestern Quebec, Canada.

During the last two months, IAMGOLD has completed a winter drilling program and seven holes had been drilled for a total of 2, 519 meters. Selected core samples have been sawn and sent to the assay laboratory. Assay results will be reported once they are received and validated by the project operator IAMGOLD. A total of 1,124 samples have been sent for analysis.

Most of the drill holes intersected the targeted structures of the Liam and Dan Zones and have also identified a new geological structure that needs further assessment. The results of the drilling program are expected over the coming weeks.

Planned summer exploration program

Planning continues for a summer exploration program which will include completion of a ground geophysical survey with the objective to characterize the alteration and mineralized zones. A 4-line orientation survey will be conducted on the Liam showing involving a deep Induced Polarization survey. If the results are successful a similar survey will be considered to attempt to delineate potential extensions of the Liam showing to support future drilling on the property. Also prospecting and structural mapping works are planned to cover selected areas of the property along the major interpreted structures.

About the Nelligan Project

The Nelligan project contains several interesting gold showings including Liam, Dan and Lake Eu. Liam and Dan showings were discovered by drilling in 2013 and 2014. These new gold structures were intersected to date over a length of 400 metres and at a depth of over 200 vertical metres. The presence of gold is constant throughout the drilling. These zones remain open along strike and at depth. Prospective showings appear to fall within a structural corridor of potential strike length of several kilometres associated to the Guercheville Deformed Corridor.
