Lithium Chile Signs Letter of Intent to Option 50.01% of the Salar de Turi Project to Monumental Minerals

To earn the 50.01% interest in the Project, Monumental must pay Lithium Chile C$700,000 over two years, incur minimum expenditures on the Project of C$1.4 million over two years and issue to Lithium Chile that number of common shares of Monumental that would result in Lithium Chile holding, on a non-diluted basis, 9.9% of the issued and outstanding common shares of Monumental after completion of their next financing.

The Lithium Triangle is an area within the central Andes high desert that includes Chile, Argentina, and Bolivia (Fig. 1) and is estimated to contain more than half of the world's lithium supply beneath the many salt flats, also known as salars, that are common to the region. The Project is comprised of 31 exploration concessions totaling 8,500 hectares, 100% owned by Lithium Chile through its wholly owned Chilean subsidiary Minera Kairos Chile Limitada ("Minera Kairos"). The Project is accessible from the city of Calama via the paved roads and is close to infrastructure.

Jamil Sader, CEO and Director of Monumental Minerals comments "The relationship we have built with Lithium Chile continues to develop into a growing joint effort to advance high value salars towards a lithium brine resource. The Salar de Turi Project represents a great opportunity, with highly compelling geophysics and geochemistry, excellent infrastructure, and year-round access. Monumental plans to move forward with exploration activities with the same vigour as we have with our other two critical metals projects, Laguna Blanca lithium brine, and Jemi heavy rare earth elements."

Steve Cochrane, President & CEO of Lithium Chile comments "During a recent trip to Chile, I met with Monumental Minerals technical and social governance team, and I feel that they have the capability as demonstrated with Laguna Blanca, to advance the Salar de Turi Project. This joint venture will benefit both parties substantially with Lithium Chile being the largest shareholder of Monumental Minerals. The Joint venture is consistent with our desire to maximize the return on our Chilean assets while our focus is on our Arizaro Argentinian development program."

During 2019, Minera Kairos completed preliminary reconnaissance and detailed geochemical and geophysical surveys:

• Transient electromagnetic (TEM) geophysics exploration work conducted by Lithium Chile delineated highly prospective brine aquifers that could contain economic grades of lithium over a 63 square kilometer (km2) area. These geophysical anomalies are shallow NE-dipping at 150 - 300 meters (m) below surface and are at least 200 to 300 m thick, often open at depth (Lithium Chile Press Release April 30, 2019) (Fig. 2).

• Near surface brine samples demonstrate return values of lithium to 590 mg/L (Lithium Chile Press Release Jan. 16, 2019). The samples also reveal favourable chemistry with ratios of lithium to potassium of 0.06; and magnesium to lithium of 7.8.

Terms of the Proposed Transaction

Subject to the execution of a definitive agreement ("Definitive Agreement"), Monumental will have the option to earn-in a 50.01% interest in the Project by making certain staged cash payments and issuing common shares to Lithium Chile and incurring exploration expenditures on Project as follows:

(a) Make cash payments of an aggregate of C$700,000 according to the following schedule:

(i) $200,000 upon final TSX Venture Exchange approval of this proposed transaction (the "Acceptance Date");

(ii) $250,000 on or before the fourteenth (14) month anniversary of the Acceptance Date; and

(iii) $250,000 on or before the second anniversary of the Acceptance Date.

(b) Incur minimum expenditures on the Project of not less than an aggregate of C$1,400,000 according to the following schedule:

(iv) $700,000 on or before the first anniversary of the Acceptance Date; and

(v) $700,000 on or before the second anniversary of the Acceptance Date.

(c) Issue and deliver to Lithium Chile, that number of common shares of Monumental that would result in Lithium Chile holding, on a non-diluted basis, 9.9% of the issued and outstanding common shares of Monumental (the "Payment Shares"), within ten (10) days of the closing of Monumental's next completed financing (if any occurs) following the Acceptance Date, but no later than the twelve (12) month anniversary of the Acceptance Date, unless otherwise mutually agreed to by both parties.

In addition to the statutory hold period of four months and a day from the date of issuance, the Payment Shares will be subject to a 12-month voluntary hold period from the date of issuance. Upon Monumental earning a 50. 01% interest in the Project, Monumental and Lithium Chile will use commercially reasonable efforts to negotiate and execute a joint venture agreement for the purpose of jointly carrying out exploration, evaluation, and development of the Project.

The proposed transaction between Monumental and Lithium Chile is subject to, among other things, the execution of the Definitive Agreement and Monumental receiving TSX Venture Exchange approval.
