ROCKLAND RESOURCES REPORTS ASSAYS UP TO 4,080 PPM LITHIUM ON

NEWLY ACQUIRED LITHIUM BUTTE CLAYSTONE PROPERTY, UTAH

Vancouver, British Columbia, June 29, 2022: Rockland Resources Ltd. (the "Company" or

"Rockland") (CSE: RKL) is pleased to report that the Company has acquired the Lithium Butte

Property located in the Basin and Range Province of west-central Utah, USA. Rockland

representatives recently took grab samples that have resulted in assays returning up to 4,080

ppm lithium from claystones derived from rhyolite tuff-breccia on the newly acquired Lithium

Butte Property.

Ten grab samples from the property were taken on a reconnaissance sampling program in May

2022. All of the grab samples are from a rhyolite tuff-breccia unit of Tertiary age that is known

to contain elevated Lithium contents. Five grab samples of the tuff-breccia that had strongly

developed clay alteration assayed from 4,080 ppm lithium to 1,200 ppm lithium with an average

of 2,142 ppm lithium. The five samples were taken from an outcropping exposure of clay altered

tuff-breccia with a stratigraphic thickness estimated to be greater than 20 m. The exposure

contains at least two intervals of claystone mineralization, each of which is several meters in

thickness.

Dr. Richard Sutcliffe, Rockland’s President stated “Although this project is at a very early stage,

we are extremely encouraged by these high-grade lithium grab samples from volcanic-derived

claystones on the Lithium Butte Property. The next stage of work will include channel sampling

to confirm the thickness of the lithium-rich claystone units on the Property. Since the claystone

is locally well-exposed and accessible to surface sampling, we anticipate that this work will be

done this summer. Lithium Butte has many of the hallmarks of successful lithium claystone

projects in the Basin and Range Province. These include: volcanic source rocks with elevated

lithium content; geothermal fluid activity; containment basins; clay altered horizons; and

favourable structure.”

The Lithium Butte Property consists of 60 lode claims on BLM lands covering approximately

1,200 acres (486 ha) in west central Utah. The Lithium Butte Property will be part of a regional

lithium exploration program that Rockland is developing in Utah. The Company is currently

staking additional claims and will provide additional Property details once staking has been

completed.

Rockland has acquired a 90% interest in the original Lithium Butte property (60 claims - 1,200

acres) by covering the staking and filing costs (paid), with the remaining 10% interest held by an

arms-length third party. All remaining claims being staked by Rockland are owned 100% by the

Company. There is a 1.5% Net Smelter Royalty ("NSR") payable to the same arms-length third

LC247418-1

party on both the original Lithium Butte property and all adjoining claims being acquired in the

area.

Assay Program QA/QC – Initial grab sampling at Lithium Butte was carried out by Dr. Richard

Sutcliffe, P. Geo., a Qualified Person as defined in NI43-101, who is also responsible for

reviewing and approving the geological contents of this news release as they pertain to the

Lithium Butte Claystone Property.

Samples were transported in sealed bags by the QP to Activation Laboratories ("Actlabs") in

Ancaster, Ontario. Actlabs is an independent ISO/IEC 17025 certified laboratory. Li analysis

was performed using sodium peroxide fusion and inductively coupled plasma mass spectrometry

(ICP-MS).

About Rockland Resources Ltd.

Rockland Resources is engaged in the business of mineral exploration and the acquisition of

mineral property assets for the benefit of its shareholders. In addition to the Utah Lithium

Property, the Company is acquiring the 41,818-hectare Elektra project concessions that are

contiguous with Gangfeng Lithium’s Sonora Lithium Clay Project located in Sonora, Mexico.

The Company also holds an option to earn a 100-per-cent interest in the Cole Gold Mines

property, located in Ball township, Red Lake mining division, Ontario. The Cole Property hosts

high-grade gold mineralization in a classic Red Lake-type structurally controlled gold deposit

environment.
