Iconic Releases Resource Report That May Indicate Bonnie Claire Is the Largest Known Lithium Resource in North America

Vancouver, British Columbia--(Newsfile Corp. - September 1, 2021) - Iconic Minerals Ltd. (TSXV: ICM) (OTC Pink: BVTEF) (FSE: YQGB) (the "Company" or "Iconic") is pleased to announce it has released an updated NI 43-101 resource report for the Bonnie Claire project (the "Property") located 48 km (30 miles) north of Beatty, Nevada. The report was done by Global Resource Engineering Ltd. ("GRE") of Denver, Colorado. Modelling the resource using two open pits in areas of shallow higher grade lithium mineralization along with borehole mining of deeper high grade mineralization GRE calculated an Inferred Resource estimate of 18.68 million tonnes of Lithium Carbonate Equivalent (LCE) (the "Resource"). This Resource is significantly larger than identified resources reported by other lithium companies in Nevada.

GRE reported using data collected from drilling results of three deep drill holes (average 550 meters or 1,800 feet) and seven shallow drill holes (average 90 meters or 300 feet) drilled to date. The resource estimate was completed using Leapfrog® Geo and Leapfrog® Edge software. GRE used three estimation methods to model Li grade into a block model: inverse distance to the second power (the "ID2"), ordinary Kriging (Kr), and nearest neighbor (NN). The block model was validated and classified as the inferred resource."

For the shallow, pit constrained resource, GRE generated pit shells using Lerchs-Grossman "pit optimizer" software, where two open pits on the Property were defined. The first identified pit is located under the shallow portion of deep hole BC 1601 and the second identified pit is located under the shallow drill holes BC 2001C, BC 2003 and BC 2006, at 3,000 meters (9,800 feet) to the south. GRE designed the pits based on experience and benchmarking against similarly defined projects. GRE states it "considers that the two blocks located within the resulting conceptual pit envelope show "reasonable prospects for economic extraction" and can be reported as a mineral resource". The Resource is reported in the table below which was extracted from the NI 43-101 technical report.

For the deeper, potentially borehole mineable and much larger resource, GRE used past experience with the technique to define the resource. Pressurized water is pumped down a large diameter drill holes and used to liquify the soft lithium-bearing sediment that is then pumped to the surface for milling or treated by in situ leaching. A large void is formed which is then filled with waste rock. For the mineral resource that may be potentially borehole mineable GRE assumes a 60% mining recovery, but do not include mining dilution, plant recovery, refining penalties, or pit constraints. This resource is also reported in the table. It should be noted that these results are mineral resources and not "mineral reserves". A prefeasibility study or feasibility study is required to state Mineral Reserves. Iconic and its JV partner, Nevada Lithium Resources Inc. have nearly completed a Preliminary Economic Assessment (PEA) also being done by GRE. Results will be released as soon as the report is finalized.

Richard Kern, Iconic's President and CEO, stated, "I am pleased that the updated 43-101 report shows such a significant mineral resource at Bonnie Claire from such a small number of drill holes. This project is beginning to get the attention it deserves, and I look forward to our upcoming PEA."

Bonnie Claire Mineral Resource Estimate

1. Cut-off grade of 500 ppm Li
2. The effective date of the Mineral Resource is May 3, 2021.
3. The Qualified Person for the estimate is Terre Lane of GRE.
4. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
5. Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.
6. The Mineral Resource is based on an assumed lithium price of 9,000 $/tonne Li2CO3, and Li2CO3 to lithium ratio of 5.323
7. For the Open-pit constraint - assumed mining cost of 2.0 $/tonne, assumed processing cost of 17.00 $/tonne , an assumed metallurgical recovery of 83%, pit slopes of 18 degrees,.
8. For the Borehole constraint - Assumes 60% recovery by borehole

Bonnie Claire Property

The Bonnie Claire Property is located within Sarcobatus Valley, which is approximately 30 km (19 miles) long and 20 km (12 miles) wide. Quartz-rich volcanic tuffs containing anomalous amounts of lithium occur within and adjacent to the valley. Drill results from the salt flat have included lithium values as high as 2550 ppm Li and a 1560 foot (roughly 475 meter) vertical intercept that averaged 1153 ppm Li. The current 43-101 report on the project notes that, with a cutoff grade of 600 ppm Li and average grade of 1,027 ppm Li, one square mile contains an inferred resource of 5.025 billion kilograms Li (though this is a resource, not a reserve, and has not yet proven economic viability). The gravity low within the valley is 20 km (12 miles) long, and the current estimates of depth to basement rocks range from 600 to 1,200 meters (2,000 to 4,000 feet). The current claim block covers an area of 74 km² (28.6 mi²) with potential for brine systems and further sediment resources.
