SENTINEL COMMENCES FIELD INVESTIGATION OF GOLD AND

SILVER PROJECTS IN NEW SOUTH WALES, AUSTRALIA

Vancouver, British Columbia, May 7th, 2021 – Sentinel Resources Corp. (CSE: SNL)(US

OTC PINK: SNLRF) (“Sentinel” or the “Company ”) announces that all of its exploration

licenses in New South Wales, Australia have now been granted. The Company has commenced

contacting landholders in high priority areas in order to negotiate the access agreements required

prior to conducting field visit s on private property. As previously announced , the Company has

identified four priority areas for initial inspection: Carrington, Hill End South , Golden Bar, and

Toolom South.

Carrington – Silver Project

At the Carrington property (EL 9127), interpretation of previous soil sampling results by Sentinel

geologists has defined two high priority gold-bismuth-antimony anomalies along a zone of historic

workings. These may be upgraded to drill targets after field confirmation. Initial contact has been

made with the landholders to discuss access arrangements.

Hill End South – Gold Project

The Hill End South property (EL 9125) lies along the southern extension of the Hill End Anticline

which hosts quartz vein mineralization of the Hill End Goldfield where approximately 50 tons of

gold have been produced from hard-rock and alluvial sources. Once land access arrangements have

been completed the focus will be on assessing the likelihood that the mapped anticline hosts saddle

reef-style gold mineralization similar to that at Hill End and at Ballarat and Bendigo in Victoria.

Golden Bar – Gold Project

The exploration team of Dr. Peter Pollard, Chief Geologist and Mr. Danny Marcos, Exploration

Manager has completed field inspection of historic gold workings within the Golden Bar

exploration license (EL 9079) which occur within Wild Cattle Creek State Forest. Historic reports

of wide zones of mineralization at the Bobo K ing and Black Bull mines were the prime focus of

investigation. However, these could not be substantiated on the ground and in both cases gold

mineralization occurs in narrow zones of quartz veining. Samples of quartz vein material collected

from the mine dumps at Bobo King, Black Bull and nearby unnamed workings returned very low

gold grades. The potential of the property has been significantly downgraded by the field

inspection and assay data.

Toolom South – Gold Project

Toolom South (EL 9080) ranked slightly lower tha n the other properties during the Company’s

internal review and Sentinel has decided to defer work on this license for the time being.

Sentinel CEO Rob Gamley commented, “Peter and his team have done a great job, bringing their

deep experience to the portfolio analysis and project work -up program we initiated two months

ago. Significant resources have been committed to this process and while we are disappointed that

the historically reported mineral values cannot be replicated, we believe that additional work is

warranted in a number of areas. We will continue the assessment work and ideally develop drill

targets shortly.”
