1246773 B.C. Ltd. Announces Proposed Acquisition of Chilean Mining Properties from 2311548 Alberta Ltd. and Business Combination to Form Atacama Copper Holdings Corp.

Toronto, March 12, 2021 - 1246773 B.C. Ltd. ("773") announces that it has agreed to complete a series of transactions with 2311548 Alberta Ltd. ("TargetCo") that will result in 773 (to be named "Atacama Cobre Ltd." as discussed below) indirectly acquiring the rights to the El Cofre Project, the Los Naranjos Project, the Caballo Muerto Project and the Placeton Project located in Chile (the "Chile Properties"). The proposed transactions will be effected through an amalgamation agreement (the "Amalgamation Agreement"). The transactions are conditional on TargetCo completing the Private Placement (as defined below) and the TSX Venture Exchange ("TSXV") approving the listing of the common shares of 773 ("Resulting Issuer Shares") and other customary conditions, with closing occurring by April 30, 2021.


Amalgamation Agreement

The Amalgamation Agreement between 773 and TargetCo provides for, among other things, a three-cornered amalgamation (the "Amalgamation") pursuant to which (i) TargetCo will amalgamate with a wholly-owned subsidiary of 773 incorporated pursuant to the provisions of the Business Corporations Act (Alberta), (ii) all of the outstanding common shares of TargetCo (each, a "TargetCo Share") will be cancelled and, in consideration therefor, the holders thereof will receive Resulting Issuer Shares on the basis of one TargetCo Share for one Resulting Issuer Share, and (iii) the amalgamated corporation will become a wholly-owned subsidiary of 773. After giving effect to the Amalgamation, the shareholders of TargetCo will collectively exercise control over 773. Pursuant to the Amalgamation, all securities of TargetCo convertible into TargetCo Shares will cease to represent a right to acquire TargetCo Shares and will provide for the right to acquire the same number of Resulting Issuer Shares at the same exercise price per share, reflecting the Exchange Ratio.

Prior to completion of the Amalgamation, it is intended that 773 will change its name to "Atacama Copper Corporation" or such other name as agreed to by 773 and TargetCo and accepted by the applicable regulatory authorities (the "Name Change").

Completion of the Amalgamation will be subject to certain conditions, including among others: (i) the requirement for TargetCo to obtain approval of all of the shareholders of TargetCo with respect to the Amalgamation by way of written resolution; (ii) the requirement for 773 to obtain approval the Name Change (which will be evidenced by a unanimous written consent resolution); (iii) completion of the Private Placement (defined below); (iv) obtaining conditional approval of the TSXV to the listing of the Resulting Issuer Shares; (v) the Exchange shall have granted an exemption or waiver from the sponsorship requirement or a sponsor shall have filed an acceptable report with the Exchange; and (vi) 773 shall not be in default of the requirements of the Exchange and any securities commission and no order shall have been issued that would prevent the Amalgamation or the trading of any securities of 773.


The Chile Properties

The Chile Properties are located approximately 650 kilometers north of Santiago close to the city of Vallenar in northern Chile. Placeton, Caballo Muerto and Los Naranjos are located within the Tertiary porphyry copper environment. El Cofre is located 30 kilometers west of Vallenar city on the Atacama fault trace on the northern extension of the San Juan Cu-Au-Co district.


Placeton Projects

The Placeton Projects which together include the Placeton, Caballo Muerto and Los Naranjos projects comprise of 7,257 hectares in thirty-nine exploitation tenements that are 100% owned by Aconcagua Minerals SpA.

Placeton is located directly between the Relincho (15 kilometers southeast) and the El Morro (25 kilometers west) projects owned by NuevaUnion, Teck Resources and Newmont Corporation's joint venture company.

Placeton shows geological features of a Cu-Mo-Au mineralized sub-volcanic complex with characteristics that are common in the upper part of many porphyry copper systems in the Andean Region. Copper mineralization is primarily hosted by an epizonal magmatic-hydrothermal system centered on small porphyritic felsic stocks and dacitic-rhyolitic dome complexes, within a cluster of at least four centers of mainly phyllic alteration within a broad propylitic background.

A number of small artisanal mines are located across the tenement area and have previously been worked in small vein structures for copper, silver and gold. Mineralization identified during the different exploration campaigns is related to small epizonal stocks and dikes of intermediate to acid nature.

Past exploration work at Placeton comprises surface mapping and geochemical sampling along defined profiles as well as two IP/resistivity profiles. No drilling has been performed up to date. This work has identified three targets of potential mineralization. Follow-up surface geological and structural mapping work, surface geochemistry, and geophysics is required to validate historical results and to define potential drill targets.

Caballo Muerto is located 10 kilometers east of the Placeton targets and 15 kilometers northwest of the El Morro project and the Los Naranjos project is located on non-contiguous tenements approximately 20 kilometers south of Relincho project. Past exploration work on both Caballo Muerto and Los Naranjos is limited to surface mapping and geochemical sampling.


El Cofre

The property comprises 7,429 hectares in thirty-seven exploration tenements (in the process of being converted to exploitation tenements) that are 100% owned by Cobalt Chile SpA.

The Cu-Au-Co mineralization at El Cofre is linked to an intense deformation zone related to the Atacama Fault System hosted within the shear zone. There are a large number of historical workings over the area. Previous exploration has included geological mapping, geochemical sampling and IP/resistivity profiles. This work has identified three targets of potential mineralization and drill targets on these areas of potential mineralization have been outlined.

As a condition of the Amalgamation, 773 is currently working to complete a technical report for the Property pursuant to the requirements of National Instrument 43‐101 - Standards of Disclosure for Mineral Projects (the "Technical Report") which will cover the Placeton and Caballo Muerto projects.


Financing Matters

TargetCo intends to complete a brokered private placement of subscription receipts at an issuance of $0.50 per subscription receipt (the "Subscription Receipts") for aggregate gross proceeds of at least CAD$4,000,000.00 (the "Private Placement"). Immediately prior to the Amalgamation, the Subscription Receipts are expected to convert into TargetCo Shares which will subsequently be exchanged pursuant to the Amalgamation for Resulting Issuer Shares. The net proceeds of the Private Placement will be placed into escrow and released to TargetCo subject to the satisfaction or waiver of a number of conditions including the completion of the Amalgamation.

The net proceeds of the Private Placement will be used by TargetCo to advance exploration on the Placeton and El Cofre projects and for general corporate purposes following completion of the Amalgamation.

The securities to be offered in the Private Placement have not been, and will not be, registered under the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act") or any U.S. state securities laws, and may not be offered or sold in the United States or to, or for the account or benefit of, United States persons absent registration or any applicable exemption from the registration requirements of the U.S. Securities Act and applicable U.S. state securities laws. This news release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.

Further details in respect of the Private Placement will be announced by 773 in a separate press release.


Stock Exchange Matters

As at the date hereof, neither the common shares of 773 nor the TargetCo Shares are listed on any stock exchange. A condition to completion of the Amalgamation is the conditional approval for the listing of the Resulting Issuer Shares on the TSXV. A listing application in respect of the Resulting Issuer Shares, which will include further details of the Amalgamation, will be filed on 773's issuer profile on SEDAR at www.sedar.com provided TSXV's conditional approval of the listing of the Resulting Issuer Shares has been obtained. There can be no assurance that the TSXV will grant such conditional approval of that the Amalgamation will be completed as proposed or at all.

773 intends to apply to the TSXV for an exemption from the sponsorship requirements for the Amalgamation based upon the Private Placement and/or other exemptions available in TSXV policies.
