BUFFALO HILLS JOINT VENTURE

TSX: DIAM

HIGH DIAMOND PRICES AND ELEVATED PROPORTIONS OF TYPE IIa DIAMONDS

Star Diamond Corporation (TSX: DIAM) ("Star Diamond" or the company) is pleased to announce that the company has completed an estimate of the diamond valuation and the abundance of Type IIa diamonds from the from K6, K14, K91 & K252 kimberlites of Buffalo Hills Joint Venture in north-central Alberta . Star Diamond and Canterra Minerals Corporation (CTM: TSX.V) each hold a 50 percent interest in the Buffalo Hills project.

Highlights

  • The diamond valuation exercise has shown that kimberlites K14 and K6 have elevated modelled diamond prices, US$ 160 per carat and US$ 180 per carat, respectively. The K6 parcel includes three fancy yellow stones, the K14 four fancy yellow and the K252 a fancy orange stone. The two highest value stones, which are both from the K6, are 1.06 carats (US$ 532) and 1.07 carats (US$ 506) . These diamond parcels are too small (carats and stones) for rigorous diamond value estimates.
  • The diamond typing exercise has shown presence of Type IIa diamonds, in elevated proportions, in all four of these Buffalo Hills kimberlites. The diamonds analysed represent a spectrum of diamond sizes from +3 DTC (+0.026 carats) to 5 grainer (1.2 carats).

Ewan Mason , Interim CEO said: "We are encouraged that the high diamond price estimates for these kimberlites are significantly above the world average rough price of US$116 (2021). This work has also shown elevated proportions of Type IIa diamonds, in addition to the stunning colours in these sample parcels. We will be discussing with our partner what further work may be warranted at site."

*Very speculative due to the small sample size

As observed by Mr. Karun, diamonds from these kimberlite bodies exhibit good quality, colour and very low to no fluorescence. All the parcels of diamonds appear to be statistically very similar in terms of their graded characteristics. There is an inadequate sample size for K91 to model the average diamond price. Extremely speculative model prices are given for samples K6 and K252, due to the small parcel size. K14 is a larger parcel size, and a price can be modeled, but should still be used with caution.

Diamond Typing

These four kimberlites have diamond parcels with sufficient diamonds to conduct preliminary diamond typing studies. The number and the percentage of Type IIa diamonds for the Buffalo Hills kimberlites studied are documented in the table below and shows that these kimberlites have an anomalously high percentage of Type IIA diamonds.

Senior Technical Advisor to Star Diamond , George Read , states: "The presence of Type IIa diamonds in the Buffalo Hills kimberlites increases the potential for the recovery of large (plus 100 carat), high-value diamonds from a future mine. Many high-value, top colour, large specials (greater than 10.8 carats) found in existing diamond deposits are Type IIa diamonds, including all ten of the largest known rough diamonds recovered worldwide. The presence of Type IIa diamonds strengthens the future potential diamond pricing of these Buffalo Hills kimberlites."

Type IIa diamonds are very rare and generally account for less than 2 percent of all natural rough diamonds mined world-wide from kimberlite deposits. Only a small number of active diamond mines regularly produce Type IIa diamonds with the most important of these mines being Cullinan Diamond Mine in South Africa , Letseng Diamond Mine in the Kingdom of Lesotho and, more recently, Karowe Diamond Mine in Botswana .

Fourier Transform Infrared ("FTIR") Spectrometry is used to determine the concentration and aggregation state of nitrogen within the diamonds using industry standard methods. All analyses of nitrogen content and aggregation state were carried out at the SRC high security diamond facility, with 24-hour video surveillance. The SRC's Geoanalytical Laboratories is accredited to the ISO/IEC 17025 standard by the Standards Council of Canada as a testing laboratory.

The Buffalo Hills Kimberlite District, which contains at least 38 individual kimberlite bodies, a number of which outcrop at surface, is located within the East Peace District of north-central Alberta, Canada . Exploration on these kimberlites started in 1996, from which small parcels of diamonds have been collected from various exploration programs on many of those considered most prospective.

Star Diamond Corporation is a Canadian based corporation engaged in the acquisition, exploration, and development of mineral properties. Shares of the Corporation trade on the TSX Exchange under the trading symbol "DIAM".

All technical information in this press release has been prepared under the supervision of George Read, Senior Technical Advisor to Star Diamond, a registered Professional Geoscientist in the Provinces of Saskatchewan and British Columbia and Mark Shimell, Project Manager, a registered Professional Geoscientist in the Province of Saskatchewan and Alberta , who are the Corporation's "Qualified Persons" under the definition of NI 43-101.

Star Diamond Logo (CNW Group/Star Diamond Corporation)

Overview
Star Diamond Corporation is a Canadian natural resource company focused on exploring and developing Saskatchewan's diamond resources. Star Diamond currently holds, through a joint venture arrangement with Rio Tinto Exploration Canada Inc. ("RTEC"), a wholly-owned subsidiary of Rio Tinto plc, a 25% interest in certain mineral properties (which include the Star – Orion South Diamond Project, or the "Project") within the Fort à la Corne diamond district of central Saskatchewan, Canada . These properties are in close proximity to established infrastructure, including paved highways and the electrical power grid, which provide significant advantages for future mine development.

The Company also holds a 50% interest in the exploration and evaluation properties and assets of the Buffalo Hills JV located in north-central Alberta, Canada . Canterra Minerals Corporation ("Canterra") holds the remaining 50% interest. Canterra is the operator of the Buffalo Hills JV.

Fort à la Corne mineral properties
On November 28, 2023 , the Company entered into a binding agreement (the "Agreement") with RTEC, providing for the transfer by RTEC to Star Diamond all of RTEC's 75% interest in the Project.

The Agreement provides that, upon closing:

  • RTEC will transfer to Star Diamond all of RTEC's 75% interest in the Project, such that the Project will be 100% owned by Star Diamond ;
  • RTEC will transfer to Star Diamond ownership of the trench cutter drill rig used by RTEC to complete its prior bulk sampling program at the Project;
  • RTEC will transfer to Star Diamond the Bulk Sample Plant located at the Project, including the TOMRA XRT diamond sorting machine that is on-site;
  • Star Diamond will issue to RTEC and/or an affiliate that number of common shares of Star Diamond that results in RTEC and its affiliates owning 19.9% of the then outstanding common shares of Star Diamond (RTEC and its affiliates currently own approximately 2.3% of Star Diamond's outstanding common shares); and
  • RTEC and Star Diamond will enter into an Investor Rights Agreement whereby, among other things, RTEC will be granted certain pre-emptive rights to maintain its 19.9% ownership interest in Star Diamond in connection with future financings undertaken by Star Diamond , and RTEC will agree to certain standstill protections provided that RTEC will have the right to increase its 19.9% ownership position in the event that Star Diamond receives an acquisition proposal.

Upon completion of the transactions that are the subject of the Agreement, Star Diamond will have full control and responsibility for the Project, the existing joint venture agreement between RTEC and Star Diamond will terminate, and Star Diamond will release and indemnify RTEC for liabilities arising from or relating to the Project, all in exchange for a $4 million payment from RTEC to Star Diamond . RTEC has agreed that it will provide on Star Diamond's behalf, for up to five years following closing, letters of credit in the aggregate amount of no more than $9.9 million to secure certain environmental remediation and reclamation obligations related to the Project. Star Diamond will be obliged to repay any amounts drawn on these letters of credit and such repayment obligations will be secured against the Project and its assets.

As of the date of this News Release, the Agreement is expected to close in the near future.

Recent activities relating to the Star - Orion South Diamond Project and Fort à la Corne mineral properties
During the first quarter of 2024, Star Diamond continued to work with RTEC and Saskatchewan Ministry of Environment representatives to ensure an orderly close to the Agreement between Star Diamond and RTEC.

Year End Results
For the year ended December 31, 2023 , the Company recorded a net loss of $2.8 million or $0.01 per share (basic and fully diluted) compared to a net loss of $68.8 million or $0.15 per share in 2022. The decrease in net loss year over year was due primarily to the prior year's impairment charge of $66.3 million combined with the mark-to-market loss on the Wescan investment offset by the elimination of the $0.9 million contingent consideration.

At December 31, 2023 , the Company had $0.6 million (2022 – $2.6 million ) in cash and cash equivalents and a working capital deficit of $(0.3) million (2022 - $2.0 million ). The decrease in working capital was a result of administrative and exploration and evaluation expenditures offset by proceeds received from the December 2023 private placement. Subsequent to December 31, 2023 , the Company closed the second and final tranche of a non-brokered private placement. However, the ability of the Company to continue as a going concern and fund its expenses in an orderly manner will require additional forms of financings.
