SENTINEL RESOURCES ANNOUNCES SUCCESSFUL
LITHIUM TEST WELL RESULTS
Vancouver, British Columbia, September 29, 2021 – Sentinel Resources Corp. (CSE:
SNL)(US OTC PINK: SNLRF) (“Sentinel” or the “Company”) and joint venture partner Hub
City Minerals Corp. (“HCM”) are pleased to announce the completion of a multi-layer
perforation and swab test of a vertical wellbore strategically located on one of HCM’s Subsurface
Crown Mineral Dispositions located in Saskatchewan. Laboratory testing returned lithium
concentrations in the Duperow formation up to 96.3 mg/l., which exceeded the Company’s target
of 74.6 mg/l.
Results from the Test Well
The target Wymark zones of the Duperow tested as follows:
Target Duperow Interval Salinities (ppm) Li Concentration (mg/litre)
Lower Wymark A & B 250,000 85.0 - 85.8
Upper Wymark E & F 262,000 89.0 - 96.3
Rob Gamley, CEO of Sentinel Resources, commented, “We are very pleased with the favourable
lithium concentrations in our brine sampling. Our next steps will include high-volume flow
testing, which is expected to occur on or before October 31, 2021. We are looking forward to
ongoing positive results of this work as we advance this highly prospective lithium brine project.”
Lithium Brine Properties Joint Venture
The lithium brine properties consist of 21 permits totaling 119,739 acres (48,457 hectares) of
Subsurface Crown Mineral Dispositions in the Williston basin of Southern Saskatchewan. Two
independent laboratories (Isobrine Solutions (Edmonton, AB) and AGAT Laboratories (Calgary,
AB) were engaged to analyze multiple zones of interest and measure lithium concentrations
present in the formation brine. Within these zones, the targeted intervals returned lithium
concentrations up to 96.3 mg/l.
Sentinel holds 67% of the joint venture with HCM holding the 33% balance.
