ICONIC RELEASES POSITIVE PRELIMINARY ECONOMIC ASSESSMENT

REPORT ON

BONNIE CLAIRE INDICATING MINIMAL ENVIRONMENTAL SURFACE

DISTURBANCE

Vancouver, British Columbia – October 1 3, 202 1 – Iconic Minerals Ltd.

(the "Company" or "Iconic") (TSX-V: ICM) (OTC: BVTEF) (FSE: YQGB) is

pleased to announce it has released Preliminary Economic Assessment report (“PEA”) 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. Using the updated NI 43 -101 resource report released September 1 by the

Company GRE determined what portion of the resource is defined as borehole mineable.

This resource, as reported in the PEA is as follows:

3. The Qualified Person for the estimate is Terre Lane of GRE.

4. 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. Assumes 68% recovery by borehole

The economic model used in the PEA only covers the first 40 years of production. GRE

has the following conclusions from the modelling.

• Average annual production of 32.3 million kg (32,300 tonnes) of LCE

• Cash operating cost of $5,974/tonne LCE

• All-in sustaining cost of $6,057/tonne LCE

• A $1.5 billion after-tax Net Present Value (NPV) at an 8% discount rate

• A 23.8% after-tax Internal Rate of Return (IRR)

• Payback period of 6.7 years

• Break-even price (0% IRR) of $6,545/tonne LCE

GRE found positive economics using borehole mining and recovery of lithium carbonate

after thermal treatment and hot water leaching. GRE stated the following:

“The Project economics shown in the PEA are favorable and robust, providing positive

NPV values at varying lithium carbonate prices, capital costs, and operating costs.”

GRE determined that even though the project is only partia lly drilled out the current

resource will only be 27% mined in the first 40 years of production. The borehole mining

method being used starts by drilling a hole to the bottom of the mineralized zone which

consists of soft clay. High-pressure water is pumped through drill holes into the formation

while simultaneously pumping the resulting loosened material out. This material would be

transported to the mill as slurry. The resulting large cavity would be filled with tailings

from the mill. The process would continue up the drill hole until the top of the mineralized

zone is reached.

Borehole mining would eliminate the need for an open pit and reduce tailings because they

are injected back into the drill holes. The environmental disturbance footprint is greatly

reduced which is a big positive for the project. The Project also has the potential for

incorporating solar power into its development due to its location in sunny Nevada.

Metallurgical testing conducted by Hazen Research Inc. of Golden, Colorado was used to

design a mineral processing flowsheet. The mined slurry reports to the mill by pipeline

where it is subjected to size separation. Using a cut size of 45 microns (µm), the coarse

fraction contained approximately 90% of the calcite and less tha n 2% of the lithium, with

a mass rejection of approximately 25%. The resulting fine fraction is calcined in a rotary

kiln with the addition of Sodium Sulfate. The calcine is subjected to a hot water leach to

extract the lithium into solution . Lithium extraction of up to 80% have been achieved to

date.

The leach solution is subjected to conventional impurity removal using neutralization and

precipitation. The majority of the sodium sulfate (as Glauber’s Salt) is recovered and

recycled to the calcination stage. Additionally, a significant portion of the process water

is recovered and recycled. Final lithium carbonate production is achieved through soda

ash precipitation and bicarbonate purification. The target is to produce a 99.5% purity

lithium carbonate product . The anticipated overall lithium recovery is 75% as final

marketable product. Although, a dditional testing may result in minor changes to the

flowsheet, Iconic believes this process will be employed at Bonnie Claire.

Included in GRE’s conclusions are the following:

“The Project economics shown in the PEA are favorable, providing positive NPV values

at varying lithium carbonate prices, capital costs, and operating costs.”

“The Project has the potential to be a major supplier of lithium products in the world, and

additional work is warranted.”

Although significant additional testing and fine tuning is needed this very large lithium

resource is beginning to show its real potential. The technical report is anticipated to be

filed and available shortly on the Company’s SEDAR profile at www.sedar.com.

It should be noted that the above results were derived using mineral resources and not

“mineral reserves”. A prefeasibility study or feasibility study is required to state Mineral

Reserves. Iconic is diligently working toward an initial feasibility study.

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 resource from

the PEA report for borehole mineable portion of the resource is 3,407 million tonnes

grading 1,013 ppm Li or 18,372 million kilograms of lithium carbonate equivalent. (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 km 2 (28.6 mi 2) with potential for brine systems and further

sediment resources.
