Lithoquest Diamonds Inc. Recovers Kimberlite Indicator Minerals with Diamond

Inclusion Chemistry

VANCOUVER, B.C., February 21, 2018 – Lithoquest Diamonds Inc. (TSX-V: LDI) (“Lithoquest”, or the

“Company”) today announced that kimberlite indicator minerals with diamond inclusion chemistry have

been recovered from composite rock samples collected on its 100% owned North Kimberley Diamond

Project located in the northern region of Western Australia.

The Kimberlite Indicator Minerals (KIMs) were recovered from composite rock samples collected in April

2017 at four targets. All grains underwent electron microprobe analysis to confirm their composition and

kimberlitic affinity. Diamond inclusion chemistry from pyrope garnet and chrome diopside was obtained

from two of the targets sampled: 702 and 1604.

“These results reinforce the prospective nature of the North Kimberley Diamond Project,” stated Bruce

Counts, President and CEO of Lithoquest. “It is remarkable to recover KIM’s at all four of the targets

sampled, particularly given how extensively the rocks have been weathered. Furthermore, it is

encouraging that the KIM’s included grains that originated from within the diamond stability field.”

Samples collected at targets 701 and 702, which were recognised in 2007, were intended to confirm the

presence of KIM’s in the surface rocks at these locations. Targets 1604 and 1605 were identified in 2016

and initial samples were collected in April 2017. More information on the targets can be found in the

corporate presentation, available on the Company’s website: https://lithoquest.com/investor-centre/.

The Company is active on several fronts. Additional kimberlite targets are being identified through a

comprehensive review of available data. In addition, composite rock samples, collected in December

2017, have been submitted to an Australian laboratory for the extraction and analysis of KIM’s. Finally,

the Company has commenced planning the 2018 field program, which is expected to commence in Q2

and will include drilling.
