Overview
Star Diamond Corporation is a Canadian natural resource company focused on exploring and developing Saskatchewan's diamond resources. In June 2017, the Company announced that it had acquired (the "Newmont Acquisition") from Newmont Corporation ("Newmont") all of Newmont's participating interest in the Fort à la Corne joint venture (the "FalC JV"), resulting in the Company owning 100% of the Fort à la Corne mineral properties (including the Project), and concurrently entered into an Option to Joint Venture Agreement (the "Option Agreement") with RTEC, a wholly-owned subsidiary of Rio Tinto, pursuant to which the Company has granted RTEC an option to earn up to a 60% interest in the Company's Fort à la Corne mineral properties (including the Project) on the terms and conditions contained in the Option Agreement (see News Release dated June 23, 2017).

In November 2019, Star Diamond received notice (the "Exercise Notice") from RTEC advising that RTEC was exercising all four of its options under the Option Agreement (see News Release dated November 15, 2020). The Company has formed a Special Committee of non-management directors to review and consider the Exercise Notice, including whether the options have been validly exercised by RTEC, to oversee the Company's dealings with RTEC including in relation to the Exercise Notice and to consider the Company's alternatives in the context of the Exercise Notice. In February 2020, the Company notified RTEC that its purported exercise in November 2019 of its four options under the Option Agreement did not comply with the terms of the Agreement (see News Release dated February 18, 2020).

While Star Diamond has not to date been provided with any meaningful data from RTEC's operations at the Project, Star Diamond believes that RTEC's continuing actions and conduct in relation to the Project are consistent with a belief by Rio Tinto that the Project warrants significant continued investment. Star Diamond believes that RTEC has expended significant funds at the Project to date, and that RTEC intends to continue doing so during 2020.

Star Diamond is committed to taking all actions necessary to ensure that the interests of the Company, its shareholders and its many Saskatchewan-based and other stakeholders are protected in connection with the Project, including by enforcing all of Star Diamond's rights under the Agreement. The Company recently announced that it has commenced legal proceedings in the Court of Queen's Bench for Saskatchewan (Judicial Centre of Regina) against RTEC in relation to RTEC's purported exercise (see News Release dated March 5, 2020).

Activities relating to the Star - Orion South Diamond Project and Fort à la Corne mineral properties
During 2019, the Company announced the results of a study into the abundance of Type IIa diamonds in the diamond parcels recovered from the Star and Orion South Kimberlites (see News Release dated March 4, 2019). This study confirmed that unusually high proportions of Type IIa diamonds are present in both the Star (26.5 percent) and the Orion South (12.5 percent) kimberlites. The diamonds analysed in this study represent a spectrum of diamond sizes from +11 DTC (+0.32 carats) through all of the large stones, up to diamonds of nearly 50 carats. Type IIa diamonds are very rare and account for approximately less than two percent of all natural rough diamonds mined from kimberlites. Type IIa diamonds usually have anhedral crystal shape and exhibit a range of elongated, distorted or irregular morphologies. Most importantly, many high-value, top colour, large specials (greater than 10.8 carats) are Type IIa diamonds, which include all ten of the largest known rough diamonds recovered worldwide, from the 726 carat Jonker to the 3,106 carat Cullinan.

During 2019, the Company announced that RTEC completed the drilling of ten bulk sample holes (trenches) on the Company's Star Kimberlite using the Trench Cutter Sampling Rig (See News Release dated October 8, 2019). The ten holes completed on the Star Kimberlite included a total of 2,351 metres of trench cutter drilling and intersected a total of 1,215.5 metres of kimberlite. Kimberlite was pumped to surface and recovered using a Kimberlite Separation Unit ("KSU"), with samples loaded and in cubic metre bulk bags, which total 6,848 in number (estimated by RTEC to be approximately 8,271 wet tonnes). As the on-site Bulk Sample Plant ("BSP") was not constructed or commissioned prior to the completion of the ten Star kimberlite trench cutter holes, the resulting 6,848 sample bags are being stored by RTEC until the on-site BSP is fully  constructed and commissioned.

The Trench Cutter Sampling Rig being utilized by RTEC consists of a Bauer BC 50 Cutter mounted on a Bauer MC 128 Duty-cycle Crane. Cutter rigs by Bauer are used around the world for complex engineering projects. Bauer has indicated that this is the first time in the world that this technology is being used in an active project to sample kimberlite at depths of up to 250 meters. At each bulk sampling trench cutter hole location, the surface was first stabilized (See News Release dated May 23, 2019). Cement is mixed with the top 20 metres of near-surface sands in order to stabilize the unconsolidated sand overburden.

The Trench Cutter Sampling Rig excavates a rectangular hole of 3.2 by 1.5 metres. Bauer and RTEC have indicated that the Trench Cutter Sampling Rig's cutter head was designed to excavate kimberlite fragments of up to 80 millimetres in diameter, which are then pumped in a slurry to the surface to the KSU. The KSU was designed to recover kimberlite fragments between 80 and 0.85 millimetres from the Trench Cutter Sampling Rig slurry. The Trench Cutter Sampling Rig and associated KSU was designed to minimize diamond breakage during sample excavation, washing and bagging.

The trench cutter samples that were collected from RTEC's 2019 bulk sampling program of the Star Kimberlite is to be processed by RTEC following construction and commissioning of the BSP. RTEC is to proceed with the processing of t. Final diamond recovery from the concentrates produced by the BSP is to be conducted at a secure off-site facility.

During the second quarter of 2019, the Company announced that RTEC completed sonic and core drilling on the Orion South Kimberlite (see News Releases dated April 15, 2019 and December 11, 2017). The sonic drilling provides a detailed log of the overburden stratigraphy above the kimberlite, while the core holes were drilled to generate detailed logs of the kimberlite geology at each locality in preparation for RTEC's anticipated bulk sampling of the Orion South Kimberlite using the Trench Cutter Sampling Rig.

Year to Date Results
For the year ended December 31, 2019, the Company recorded a net loss of $4.1 million or $0.01 per share (basic and fully diluted) compared to a net loss of $4.6 million or $0.01 per share in 2018. The losses during 2019 and 2018 were primarily due to ongoing operating costs and exploration and evaluation expenditures incurred by the Company exceeding interest and other income earned.

Selected financial highlights include:

Outlook
The provincial environmental approval of the Star - Orion South Diamond 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 PEA shows 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 Company's Fort à la Corne mineral properties (including the Star - Orion South Diamond Project) and the concurrent earn-in arrangement with RTEC defined the start of a new phase for the Company. There are some 60 other kimberlites within the Company's Fort à la Corne diamond district, on mineral dispositions held 100 percent by the Company. The Company is also very pleased to continue to have Newmont Corporation as a significant shareholder.

As of March 26, 2020, the Company had approximately $7.2 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 2020 programs (including flow-through commitments) to further assess, evaluate and advance certain aspects of the Company's mineral properties, as well as for general corporate matters.
