Xiana Enters into a Long Term Mining Assignment of an Advanced Exploration Propery in Castrovirreyna District, Peru

Vancouver, British Columbia--(Newsfile Corp. - May 30, 2018) - Xiana Mining Inc. (TSXV: XIA) ("Xiana" or the "Company") is pleased to announce that Xiana Peru Mining S.A.C ("Xiana Peru") (a wholly-owned subsidiary of Xiana) has entered into a mining assignment agreement ("Santa Ines Assignment") with Compania Minera Santa Ines Y Morococha S.A. ("Santa Ines") in respect of mining concessions, property and assets comprising the Santa Ines mine (the "Santa Ines Mine"), located in the Castrovirreyna district in Peru.

Commenting on the Santa Ines Assignment, Carlos Ballon, Chairman & CEO said: "Santa Ines is an excellent brownfield opportunity for Xiana. The mine had been in operation for over 70 years before being recently put on care and maintenance. The property has significant exploration potential and with available infrastructure on site, this represents an ideal value creation opportunity for Xiana. Our team is excited by the prospectivity of the region and we look forward towards realisation of our Chile-Peru focussed base metals growth strategy."

Overview of Santa Ines Mine

• The Santa Ines Mine is a property located in the Castrovirreyna district in Huancavelica, 445km south east of Lima

• The property has good access through roads and highways. Santa Ines Mine has been in operation for over 70 years with existing plant of 2,000 tpd on site. The Santa Ines Mine is currently on care and maintenance

• The Castrovirreyna district has been the source of high-grade vein silver ore since colonial times. Over the last half century, a series of steeply dipping veins have been mined underground and recently in responses to high silver prices, in small shallow open pits, for silver-lead-zinc ore

• The veins at Santa Ines Mine are concentrated along the west-east side of a large argillized and oxidized alteration zone in sectors

• Two types of mineralization have been encountered (i) silver-lead-zinc vein system, of intermediate-sulphidation epithermal type and (ii) one or more porphyry copper centres are believed to be present in the district, most likely at depth.

• A total 25 veins outcrop within the concession areas, many of which have not been drill tested

• The exploration potential at Santa Ines Mine is considered excellent. Xiana has developed a work program aimed at evaluating the existing mining developments with a view to evaluating where to direct exploration toward higher grade zinc mineralisation and evaluation of other exploration targets in the district wide concessions
