SENTINEL RESOURCES: CEO LETTER TO SHAREHOLDERS

Vancouver, British Columbia, December 21, 2020 – Sentinel Resources Corp. (CSE:

SNL)(US OTC PINK: SNLRF) (“Sentinel” or the “Company ”) is pleased to release its 2020

Annual Shareholder Letter from the CEO sent to all shareholders.

Dear Shareholders,

As 2020 draws to a close, this seems to be an appropriate time to reflect on the accomplishments

we have made to-date and comment on the path forward.

Due to the work already completed by Sentinel’s distinguished and highly experienced technical

team, it is my firm opinion that Sentinel represents a unique investment opportunity, particularly

in the Australian gold and silver exploration space.

This last year has been filled with successful corporate initiatives, strategic property acquisitions,

and carefully planned and executed exploration programs. Australia is a premier mining

jurisdiction and the Company has successfully put together one of the largest land positions in

New South Wales – quite a unique position for a junior of our size to be in. The acquisition of 8

gold and 7 silver projects within the prolifically mineralized Lachlan and New England Orogenic

belts provides the Company w ith a robust exploration portfolio on which to build. The vast

historical data set and numerous high -grade historic gold and silver mines and exploration

prospects provide a very real opportunity for discovery and development of potentially world-class

deposits.

2020 Highlights:

• Addition of an experienced exploration and development team in Dr. Peter Pollard, Danny

Marcos and Dr. Chris Wilson. Collectively, over 90 combined years of experience in over

80 countries, across almost all commodities and de posits types, from grass roots through

to resource definition and advanced project development.

• Acquired, by staking, eight, gold-focused exploration concessions totalling approximately

94,500 hectares in New South Wales, Australia. At least 198 historic gold mines and gold

exploration prospects are present across the tenements. Historic production records

indicate that gold grades were often multi -ounce (see News South Wales Department of

Planning, Industry and Environment).

• Acquired, by staking, seven, silver-focused exploration concessions totaling approximately

38,600 hectares in New South Wales, Australia. At least 23 historic silver and 3 historic

gold mines and exploration prospects are present across the tenements. Historic production

records indicate that silver grades were generally high -grade and exceeded 1 kg/t Ag in

some instances (see News South Wales Department of Planning, Industry and

Environment).

• Entered option agreement to acquire up to a 100% interest in the historic Waterloo silver-

gold property, totalling 3,130 hectares near Vernon, British Columbia . The Company

reported significant results from its 2020 confirmation sampling program, assaying up to

7,470 g/t silver and 39 g/t gold in selected grab samples. The property has not bee n

systematically drill tested and numerous untested targets are defined.

• Acquired the 2,700 hectare Salama Gold Project in western Peru, consisting of four gold

focused mining concessions situated within the prolific gold -polymetallic Miocene skarn

and porphyry belt. First pass mapping and sampling underway.

Technical Progress - Target Generation A Priority

There is an old saying that "the best place to look for gold is in the shadow of a head frame". To -

date, technical work has been low -cost activities - office-based compilation, processing, and

interpretation activities of data from historic gold and silver mines and showings that has resulted

in some significant advances in knowledge on all of the Company's properties. Of primary

importance has been the prioritization of projects and ranking of drill targets which will allow us

the opportunity to be able t o deploy capital very efficiently and effectively to drill test refined

targets.

2021 Outlook

With this newly re -interpreted information, the team has narrowed down areas of prime interest

and within those areas generated and refined specific targets ready for drill testing in 2021, subject

to measured and appropriate funding . Over the next year, management will be focused on

maximizing shareholder value through executing carefully planned exploration programs on our

Australian projects . Additionally, consistent with our corporate strategy, the Company will

continue to look for opportunities to acquire high impact precious metals assets with low entry

cost and district scale potential.

As CEO of Sentinel Resources Corp., I want to thank you for your continued support of the

Company and its gold and silver discovery program. We have a large, highly prospective ,

significantly de-risked property portfolio in a good jurisdiction and solid m anagement and

year for our company!
