Crystal Exploration Sample Results

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb 22, 2017) - CRYSTAL EXPLORATION INC. (the "Company" or "Crystal") (TSX VENTURE:CEI) is pleased to report a series of results from Crystal's 100% owned Muskox and Hood Project areas.

All the existing archived drill core has now been logged and sampled in a series of 7 composite samples from the Muskox Kimberlite. The results are summarized below in Table 1. The samples were processed using the Saskatchewan Research Councils ("SRC's") Dense Media Separation ("DMS") plant to recover commercial sized (approximately +0.85 mm), macro-diamonds.

The combined grade from the DMS processing for the magmatic kimberlite samples is 0.45 carats per tonne ("cpt") and the combined grade from the DMS processing for the pyroclastic kimberlite samples is 0.19 cpt. The largest diamonds recovered include 0.49 carats, 0.40 carats and 0.30 carats (see diamond pictures below). The diamonds are described as off-white, transparent to translucent with minor inclusions.

Caustic fusion was completed on two rock samples collected from the Muskox Kimberlite. The samples were mantle xenoliths and contained 7 diamonds and 45 diamonds respectively. The results are shown in Table 2.

Caustic fusion was completed on two composite rock samples collected from the James River Kimberlite Dyke at surface, located at the Hood Project confirming it is diamondiferous and warrants further exploration. In total, 4 microdiamonds were recovered from sample 16DBP500. The James River Dyke is only 15km from the diamondiferous Tenacity Kimberlite. A high priority drill target developed by Crystal during 2016 exists along the structure that hosts the James River Kimberlite Dyke. The results are shown in Table 2.
