Micrex Update on Current Events at Quebec Granite Property

September 6, 2017 - Micrex Development Corp. (TSX.V : MIX) ("Micrex" or the Company) wishes to provide an update on its Quebec granite quarry business, which appears to finally be poised to generate income. Micrex is receiving indications of orders pending approval of samples. The city of Ottawa has expressed interest in a large order for cobble stones. The federal government has approved an $500,000 order for paving stones, but the Company is awaiting a purchase order and shipping instructions.

Micrex has set up a crushing operation at the site to process granite aggregate, mainly for highway departments and railroads for ballast. The first order of 50 tons of crushed aggregate has been shipped. The granite produced by Micrex is sulfite free which makes it much more valuable.

An inventory of large pre-cut blocks (7 tons each) is being reviewed this week by a major quarry operator who has expressed an interest in purchasing all of them.

Micrex Development Corp. (TSX.V: MIX) is a mineral exploration company based in Alberta, Canada with mining properties in North America.
