STAR DIAMOND CORPORATION ANNOUNCES 2021 YEAR END RESULTS

Star Diamond Corporation (“DIAM”, “Star Diamond” or the “Company”) reports that the audited results of its

operations for the year ended December 31, 20 21 will be filed today on SEDAR and may be viewed at

www.sedar.com once posted. A summary of key financial and operating results is as follows:

Highlights

- Announced binding agreements and revised arrangements with Rio Tinto Exploration Canada Inc. (“Rio Tinto

Canada”) that comprehensively resolve all disputes

Overview

Star Diamond Corporation is a Canadian natural resource co mpany focused on exploring and developing

Saskatchewan's diamond resources. As a result of t he December 2021 agreements (as discussed below), the

Company is now in an enhanced position for the advancement of the Star - Orion South Diamond Project

(“Project”) and other kimberlite bodies in the Fort à la Corne diamond district.

Fort à la Corne mineral properties (including the Project) Agreements with Rio Tinto Canada

In December 2021, the Company entered into binding agreements with Rio Tinto Canada that comprehensively

resolved all disputes between them (see News Release and related filings dated December 9, 2021). As part of

these agreements, Star Diamond and Rio Tin to Canada agreed to revised arrangements. Under these new

arrangements:

• All expenditures on the Fort à la Corne properties prior to December 31, 2021 are the sole responsibility

of Rio Tinto Canada;

• All expenditures incurred between January 1, 2022 and the public announcement of a decision to develop

a diamond mining operation, based upon the completion of a positive feasibility study, will initially be

advanced by Rio Tinto Canada. Star Diamond is not required to begin reimbursing Rio Tinto Canada for

Star Diamond’s share of these expenditures unless and until commercial production has been

achieved. As a result, Star Diamond is under no obligation to contribute additional investment to the

project until a decision to develop the mine is made and publicly announced;

• Once the decision to develop the mine has been announced, Star Diamond will have six months to begin

contributing Star Diamond’s share of the capital costs and expenditures required to build the mine; and

• In exchange for these amendments, the participating interests of Rio Tinto Canada and Star Diamond in

the joint venture agreement were adjusted to 75% for Rio Tinto Canada and 25% for Star Diamond (from

60% and 40%, respectively, as per the previous Option Agreement).

These arrangements are intended to ensure that key project milestones, and the certainty associated with them,

will have been achieved before Star Diamond has to contribute any additional capital.

Activities relating to the Star - Orion South Diamond Project and Fort à la Corne mineral properties

During 2019, the Company announced that Rio Tinto Canada completed the drilling of ten bulk sample holes

(trenches) on the Company’s Star Kimberlite using the Trench Cutter Sampling Rig. These ten trench cutter holes

included a total of 2,351 metres of tre nch cutter drilling and intersected a total of 1,215.5 metres of kimberlite.

2

Kimberlite was pumped to the surface and recovered using a Kimberlite Separation Unit, with samples loaded

and stored in cubic metre bulk bags. During the second quarter of 2020, the Company announced that Rio Tinto

Canada had commenced the processing of bulk samples from Rio Tinto Canada’s trench cutter program on the

Star Kimberlite (see News Release dated April 23, 2020). The mineral concentrates produced by the on -site bulk

sample plant were shipped by Rio Tinto Canada to an off-site facility for diamond recovery and reporting of such

recovery to Star Diamond and Rio Tinto Canada. The results reported from the ten trench cutter holes were

reported by Star Diamond in 2020 and 2021. The results reported from these ten reported trenches continue to

validate the grades outlined in the independent Preliminary Economic Assessment (the “ PEA”) which was based

upon Star Diamond’s own prior underground bulk sampling and large diameter drilling programs. The recovery of

larger diamonds from Rio Tinto Canada’s bulk sample program, including larger Type IIa diamonds, also continues

to strengthen the expectation for recovery of large, high value diamonds in a future producing diamond mine.

During February 2021, Rio Tinto Canada provided written notice to Star Diamond that Rio Tinto Canada had

successfully completed its ten-trench cutter hole bulk sample pro gram (see News Release dated February 22,

2021). Rio Tinto Canada also confirmed to Star Diamond that this bulk sample program had met Rio Tinto Canada’s

objective of improving confidence in the diamond grade of the Project.

During the first quarter of 20 21, the Company announced that Rio Tinto Canada had commenced an eight -hole

geotechnical drilling program on and in proximity to the Orion North Kimberlite (see News Release dated January

19, 2021). The drill rigs utilized were capable of sonic drilling to obtain representative samples of the glacial

overburden and core drilling for the underlying kimberlite or host rock sediments. Star Diamond was advised that

the aim of this drilling was to investigate the geotechnical properties of the overburden, kimberlite and host rock

sediments, with this information to be used for open pit design. Parts of the Orion North Kimberlite have

shallower overburden than the Star and Orion South Kimberlites.

Rio Tinto Canada has indicated to the Company that a number of des ktop studies have been undertaken to

evaluate the mineability and economic viability of the Project (see News Release dated February 17, 2022) . Star

Diamond recently received presentations from both R io Tinto Canada and Rio Tinto personnel concerning data

analysis and exploration activities that have been underway by Rio Tinto Canada over the last two years (see News

Release dated March 9, 2022) . Topics of interest covered during these technical meetings included : 1) Star

Kimberlite trench cutter bulk sampling program results, 2) D iamond size and quality analysis, 3) ‘ Orbit’ project

update, 4) Mineability study, 5) G eological model and resource update, 6) C ommunity and stakeholder

engagement, 7) Environmental and permitting and, 8) Green energy and carbon mineralization.

Rio Tinto Canada has informed Star Diamond that it intends to submit an additional program and b udget to the

“FalCon Project Joint Venture Management Committee” of the Fort à la Corne project (the “JVMC”) for the period

commencing May 31, 2022. Star Diamond will be reviewing materials relating to these topic areas with Rio Tinto

Canada as the Company collaborates on 2022 programs and the budget to be approved by the JVMC.

Star Diamond, in concert with a number of external consultants, is also in the process of completing a diamond

breakage study.

Year to Date Results

For the year ended December 31, 2021, the Company recorded a net loss of $7.7 million or $0.02 per share (basic

and fully diluted) compared to a net loss of $6.1 million or $0.01 per share in 20 20. The losses during 2021 and

2020 were primarily due to ongoing operating costs and exploration and evaluation expenditures incurred by the

Company exceeding interest and other income earned.

Outlook

The provincial environmental approval of the Project received in 2018, alongside the previous positive federal

decision, marked a major milestone for the Project. In addition, the positive results of the 2018 independent PEA

show that the Project can be economically developed and operated while providing direct employment for

hundreds of people throughout the construction phase and hundreds of people continuously over its estimated

38 year mine life.

The successful completion of the 2017 consolidation of the Fort à la Corne mineral properties (including the

Project) and the amended Fort à la Corne joint venture agreement that was announced in December 2021 defines

a new phase for the Company. Under the amended Fort à la Corne joint venture agreement , expenditures

incurred at the Fort à la Corne properties ("carried interest costs") from and after January 1, 2022 are to be 100%

advanced by Rio Tinto Canada in the first instance until, among other thin gs: (a) the completion of a feasibility

study demonstrating that extraction of diamonds is reasonably justified (economically mineable) and that

contemplates the construction and operation of a diamond mining operation having certain minimum

requirements; (b) a positive decision has been made to develop such mine ; (c) a development program and

budget for the construction of such mine has been approved ; and (d) public disclosure has been made of the

decision to develop such mine. Star Diamond will have no obligation to fund or contribute to carried interest costs

until the commencement of commercial production, which will not occur until after the completion of

construction of the diamond mine with it generally operating at certain specified thresholds for 9 0 days. Once a

decision to develop the mine has been made and publicly announced, Star Diamond will have six months before

it is required to begin contributing to its share of capital costs and expenditures incurred for construction of the

mine. As part of the December 2021 amendments, the respective participating interests of Rio Tinto Canada and

Star Diamond were adjusted to 75% for Rio Tinto Canada and 25% for Star Diamond.

As of March 29, 2022, the Company had approximately $ 1.3 million in cash and cash equivalents (excluding $0.6

million in restricted cash). A portion of the Company’s cash and cash equivalents will be used for programs

4

(including remaining flow-through commitments) to further assess, evaluate and advance certain aspects of the

Company’s mineral properties, as well as for general corporate matters.

The Company recently announce d that it intends to raise up to $ 5 million by way of a non -brokered private

placement of units of the Company (collectively, the "Units") at a price of $ 0.30 per Unit (the "Offering") (see

News Release dated March 16, 2022). Each Unit will consist of one common share in the capital of the Company

(each, a " Common Share ") and one Common Share purchase warrant ( each, a "Warrant"). Each Warrant will

entitle the holder thereof to purchase one Common Share at a price of $0.40 for a period of 24 months from the

date of issuance.
