It plans to process 10,000t of mineralised material and resume operations at the existing 30t per day gravity separation mill.
"The bulk sample will test recoveries from the gravity circuit in potential future mining operations, in a mine that historically produced 18,000 ounces of gold at an average grade of 39g/t," president Andrew Rees said.
The Engineer gold mine was said to have produced 18,000oz of gold and 9,000oz of silver at 39g/t and 18g/t respectively, primarily from two veins between 1912-1927 from eight mine levels.
The property has 5,500m of underground development and fifth level portal access with rail.
The company believes the under-explored project shares similar geological characteristics with the Cripple Creek mine in Colorado, Emperor in Fiji and Midas in Nevada.
The project's Engineer vein has a high-grade core with an inferred resource of 14,000t at 52.5g/t gold for 23,600oz, using a 25g/t cut-off, according to a 2018 technical report.
The company had purchased the surface rights to part of the property in September, which included mining equipment.
Engineer was spun out of Blind Creek Resources in mid-2018 to focus on the property near Atlin.
The company last raised C$500,000 at 6c per unit in July.
Its shares (TSXV: EAU) have ranged from 3-21c over the past year and closed unchanged yesterday at 6c, to capitalise it at $3.6 million (US$2.8 million).
