VANCOUVER, B.C., June 5, 2019 – Lithoquest Diamonds Inc. (TSX-V: LDI) (“Lithoquest”, or the “Company”) today announced that it has commenced the 2019 field program on its 100% owned North Kimberley Diamond Project in Western Australia.

“The Company is well positioned to discover diamond bearing kimberlites on the North Kimberley Diamond Project in 2019″, stated Bruce Counts, President and CEO of Lithoquest Diamonds Inc. “A highly qualified technical team has now been deployed to evaluate over 20 priority targets in advance of a drill program scheduled for later this season. Data obtained from the 2018 program, highlighted by the 1804 kimberlite discovery and positive diamond results from bedrock and stream samples, have been critical in defining the areas of focus for this year’s program.”

The 2019 field program will be conducted in two phases. The first phase will concentrate on assessing prospective areas identified by the Company with the objective of selecting and prioritizing targets for drill testing (see news release dated April 30th, 2019). The priority areas are illustrated by the image of Target 1827 below and by images on the Company’s website: www.lithoquest.com/project/. Exploration activities during this period will include geological mapping, prospecting, ground geophysical surveying and sampling for kimberlite indicator minerals.

The second phase of the field program will focus on testing the most prospective kimberlite targets using a reverse circulation drill. Phase two is expected to commence in late August. The budget for the 2019 program will vary depending on the amount of drilling conducted but is expected to total approximately $2.0 million.

The 2019 field program is being directed by Mr. Dave Skelton P.Geol. and Mr. Tom Reddicliffe FAusIMM. Mr. Skelton has more than 25 years of diamond exploration experience and was involved in the discovery of several kimberlite fields including the Buffalo Head Hills cluster. Mr. Reddicliffe has more than 40 years of diamond exploration experience in Australia and is credited with the discovery of the Merlin Diamond Mine.
