SCANDIUM INTERNATIONAL UPDATE ON PATENT FILINGS

Scandium International Mining Corp. has provided an update on its United States patent office and select foreign patent office filing program, securing rights to company intellectual property in relation to the extraction and recovery of scandium values from ores, solutions and byproducts, the conversion of scandium intermediates into master alloy, and the composition and manufacturing of certain commercial scandium-containing alloys.

Highlights of Scandium International patent program:

• Three granted U.S. patents, all of planned or potential use to the Nyngan scandium project flowsheet and potentially to other scandium project flowsheets;
• Six pending U.S. patent applications, covering various scandium recovery options applicable to the Nyngan project resource. One pending U.S. patent application, covering scandium recovery from low-grade solutions;
• Three pending U.S. patent applications, related to the production of scandium master alloy, from intermediary products or scandium oxide product;
• Certain corresponding patent applications have also been filed as a foreign or a specific country application (in example, Australia).

Discussion

The company has received three approved (granted) United States patents on scandium recovery processes that are currently in the definitive feasibility study flowsheet, or are anticipated to be of potential future use at the Nyngan scandium project, or other possible scandium projects.

Details on these granted patents are as follows:

• USP 9,982,325 -- "Systems and methodologies for direct acid leaching of scandium-bearing ores," granted in May, 2018, to Scandium International. This patent covers and protects various hot-tank and heap leaching techniques for scandium ores, employing heat and acids under atmospheric conditions.
• USP 9,982,326 -- "Solvent extraction of scandium from leach solutions," granted in May, 2018, to Scandium International. This patent covers and protects novel and scandium-specific solvent extraction techniques, chemistries and reagents employed in the Nyngan feasibility study.
• USP (number not yet assigned) -- "Method and recovery of scandium values from leach solutions." Granted in January, 2019, to Scandium International. This patent is closely related to SX patent No. 326, as mentioned before in this news release, although it extends scandium-specific SX protections, when coupled to select upstream acid leaching processes or for use of organic solvents in SX systems.

These three granted patents either have direct, planned use or potential use for the Nyngan scandium project, or for other possible projects related to scandium. Separate patent applications related to the high-pressure leaching (autoclave) systems planned to be employed at Nyngan are still being reviewed by the U.S. patent office.

Further patent applications will be filed as needed to continue to protect Scandium International's interest in scandium recovery from various resources and marketing scandium products, especially as they relate to novel applications for scandium. Copies of its granted patents will be made available shortly on the company's website

George Putnam, chief executive officer of Scandium International, commented:

"The company has made considerable investment in the study and development of flowsheet designs for scandium recovery, and also for scandium product upgrades matching customer preferences. This intellectual property is being secured through the U.S. patent system, and corresponding foreign patent systems, for our shareholders and for our projects, current and future."

About Scandium International Mining Corp.

The company is focused on developing its Nyngan scandium project, located in New South Wales, Australia, into the world's first scandium-only producing mine. The project, owned by its 100-per-cent-held Australian subsidiary, EMC Metals Australia Pty. Ltd., has received all key approvals, including a mining lease, necessary to proceed with project construction.

The company filed a National Instrument 43-101 technical report in May, 2016, titled "Feasibility Study -- Nyngan Scandium Project." That feasibility study delivered an expanded scandium resource, a first reserve figure and an estimated 33.1-per-cent internal rate of return on the project, supported by extensive metallurgical testwork, and an independent, 10-year global marketing outlook for scandium demand.

Willem Duyvesteyn, MSc, AIME, CIM, a director and chief technical officer of the company, is a qualified person for the purposes of NI 43-101. He has reviewed and approved the technical content of this press release on behalf of the company.
