Star - Orion South Diamond Project initial Results from Third Bulk Sample Trench: 2,822 Diamonds Weighing 130.26 Carats Recovered, Including 6.28 Carat Stone

Stock Symbol: DIAM: TSX

Star Diamond Corporation ("Star Diamond" or the "Corporation") announces that a total of 2,822 diamonds weighing 130.26 carats have to date been recovered from the third bulk sample trench (19FALCT003) excavated on the Star Kimberlite. These initial results are from the third of ten bulk sample trenches that were excavated by Rio Tinto Exploration Canada Inc. ("RTEC") in 2019 (see news releases dated June 3 and October 8, 2019 ). The breakdown of the kimberlite intercepted, and diamonds recovered to date from trench 19FALCT003, are detailed in Table 1 below.  The preliminary results from the first two bulk sample trenches were previously disclosed by Star Diamond on August 4, 2020 and August 20, 2020 respectively.

The average diamond grades from the first three trenches are similar to historical diamond grade results detected from the underground bulk sampling and large diameter drilling ("LDD") completed on the Star Kimberlite between 2004 and 2009.  These results are also similar to the overall weighted average grade (14 cpht) reported in Star Diamond's Preliminary Economic Assessment(" PEA") of the Star and Orion South kimberlites (the "Project") (see news release dated April 16, 2018 ).

The three largest diamonds recovered to date from 19FALCT003 are 6.28, 1.95 and 1.49 carats, respectively, and were all recovered from Early Joli Fou ("EJF") kimberlite. The 6.28 carat stone is a clivage fragment of a larger stone that was probably fragmented during the original kimberlite eruption as all surfaces of this stone have been resorbed by reaction with the kimberlite magma. The EJF is the dominant kimberlite unit within the Project in terms of ore volume and diamond grade.

As disclosed by Star Diamond on August 4, 2020 , there are indications that recent diamond breakage has occurred in the diamond parcels recovered thus far from RTEC's trench cutter bulk sampling program, suggesting that the extraction and/or processing systems being used by RTEC may be resulting in diamond breakage.  Comprehensive diamond breakage studies are required to assess the nature, extent and potential causes of the diamond breakage, and the possibility that larger diamonds would have been recovered absent such breakage.

Senior Vice President Exploration and Development, George Read , states: "The initial diamond results from 19FALCT004, 19FALCT001 and 19FALCT003 continue to show grades similar to the previous underground bulk sampling and LDD performed by Star Diamond on the Star Kimberlite. Individual EJF kimberlite samples recovered in the first three trenches exhibit a range of grades (9.81 to 21.22 cpht for 19FALCT004, 4.88 to 23.34 cpht for 19FALCT001 and 8.71 to 23.39 cpht for 19FALCT003), which are as expected for the EJF kimberlite."

To date, kimberlite material from six trenches (19FALCT001, 19FALCT004, 19FALCT003, 19FALCT010, 19FALCT008 and 19FALCT009) has been processed by RTEC through the on-site Bulk Sample Plant (the "BSP"), with concentrates forwarded to the Saskatchewan Research Council ("SRC") for diamond recovery and reporting.  Currently, only the initial diamond results for the first three trenches have been reported by the SRC.

1,094 carat rough diamond from Lucara Diamond's Karowe mine.

Lucara Continues Streak of Big Diamond Discoveries with 1,094 Carat Find at Karowe

Only a month after the discovery of the second largest diamond ever recorded, Lucara Diamond (TSX:LUC,OTC Pink:LUCRF) has announced the recovery of another significant stone from its Karowe mine in Botswana.

The new find is 1,094 carats compared to the massive 2,942 carat rough diamond uncovered by Lucara in August, solidifying Karowe’s reputation as one of the world’s most prolific sources of large diamonds.

The rough diamond is the sixth stone over 1,000 carats that Lucara has unearthed from the mine. According to the company, the EMPKS ore type at Karowe's South Lobe hosts these large, high-value stones.

Star Diamond Corporation ("Star Diamond" or the "Company") is pleased to announce that the Technical Report documenting the Revised Mineral Resources Estimate (see News Release dated July 24, 2024 ) for the Star Orion South Diamond Project (the "Project") has been filed on SEDAR+ ( www.sedarplus.ca ). This Technical Report has also been posted on the Star Diamond website: Technical Report 2024 .

Star Diamond Corporation logo (CNW Group/Star Diamond Corporation)

The scientific and technical information contained in this press release has been prepared and verified by A.C.A. Howe International Limited ("Howe"), under the supervision of Mr. Daniel C. Leroux, M.Sc., P. Geo. and the Mineral Resource estimation methodology under the supervision of Peter Ravenscroft , FAusIMM, of Ravenscroft Mining Advisors, an independent mining consultant, and a Qualified Person ("QP") within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") of the Canadian Securities Administrators. This Revised Mineral Resources estimate uses diamond industry standard methods which are rigorously applied to the Star and Orion South evaluation data, acknowledging the significant control that fundamental kimberlite geology has on the distribution of diamonds within these deposits.

The Revised Mineral Resources estimate will now be incorporated into a re-optimized open pit mine plan for the Project, which will include a re-evaluation of Mineral Reserves and an economic assessment based thereon. It is anticipated this work will be completed during 2024-25 and will result in an updated Pre-feasibility Study including a revised statement of Mineral Reserves for the Project, if warranted, and an economic assessment based thereon. Accordingly, the Mineral Resources and economic assessment previously disclosed by Star Diamond for the Project should no longer be relied upon.

Lucara Diamond (TSX:LUC,OTC Pink:LUCRF) announced the discovery of an "epic" 2,492 carat diamond at its Karowe mine in Botswana on Wednesday (August 21), saying it is one of the largest rough diamonds ever found.

Media reports indicate that it is second only to the 3,106 carat Cullinan diamond found in South Africa in 1905.

The site where the diamond was discovered is no stranger to producing large stones. Previous significant discoveries from Karowe include the 1,758 carat Sewelô and the 1,109 carat Lesedi La Rona diamonds.

STAR DIAMOND CORPORATION COMPLETES ACQUISITION OF BUFFALO HILLS DIAMOND PROJECT

Stock Symbol: DIAM: TSX

Star Diamond Corporation ("Star Diamond" or the "Company") is pleased to announce that further to its press release dated July 15, 2024 it has completed the acquisition of Canterra Minerals Corporation's ("Canterra") interest in the Buffalo Hills Diamond Project (the "Project"). Star Diamond now owns 100% of the Project.

Star Diamond logo (CNW Group/Star Diamond Corporation)

Star Diamond acquired Canterra's 50% interest in the Project, a land package consisting of 21 mineral leases covering approximately 4,800 hectares located 400 kilometres northwest of Edmonton, Alberta, Canada , in exchange for the issuance of 17,500,000 common shares of the Company (the "Consideration Shares"). One half of the Consideration Shares are subject to a 12-month lock-up arrangement. In addition to the Consideration Shares, Canterra was granted a 1% royalty interest in the Project.  All of the Consideration Shares are subject to a customary four month hold period.

About Buffalo Hills Diamond Project
Located approximately 400 kilometres northwest of Edmonton, Alberta, Canada , the Buffalo Hills Diamond Project includes 21 mineral leases covering 4,800 hectares and is a significant and accessible field of diamond bearing kimberlites, with similarities to the Fort á la Corne kimberlites in Saskatchewan, Canada . The Project is located in the Buffalo Hills Kimberlite District, which contains at least 38 individual kimberlite bodies, of which 26 kimberlites are diamond bearing and a number of which outcrop at surface. Exploration on these kimberlites started in 1996, and small parcels of diamonds have been collected from various exploration programs on many of those considered most prospective.
