TORONTO, ON / ACCESS Newswire / August 11, 2026 / Prospectiva Resources Ltd. ("Prospectiva" or the "Resulting Issuer") (formerly Pentagon I Capital Corp. ("Pentagon")) is pleased to announce the completion of its previously announced business combination (the "Transaction") with Prospectiva Resources Ltd. ("Prospectiva UK"), a privately-held mineral exploration company focused on copper and gold exploration in Brazil. The Qualifying Transaction constitutes Pentagon's "Qualifying Transaction" under Policy 2.4 - Capital Pool Companies (the "CPC Policy") of the TSX Venture Exchange (the "TSXV").

The Resulting Issuer has changed its name from "Pentagon I Capital Corp." to "Prospectiva Resources Ltd." (the "Name Change"). Prospectiva has made its final submission to the TSXV pursuant to CPC Policy to seek final TSXV acceptance of the Transaction. It is anticipated the common shares of the Resulting Issuer (the "Resulting Issuer Shares") are expected to commence trading on the TSXV under the symbol "PSVA" on or about August 14, 2026 (the "Trading Date"), subject to the Resulting Issuer fulfilling all of the requirements of the TSXV. Trading of Prospectiva's shares will remain halted until such time as the TSXV may determine, having regard to the completion of certain requirements pursuant to the CPC Policy.

The Transaction

The Transaction was completed in accordance with the terms of a definitive agreement dated July 7, 2026 (the "Definitive Agreement") among Pentagon, Prospectiva UK and the shareholders of Prospectiva UK. Pursuant to the Definitive Agreement, a wholly owned subsidiary of Pentagon incorporated under the laws of the Province of Ontario ("Subco") amalgamated with Prospectiva Canada Finco Inc. ("Finco"), a wholly owned subsidiary of Prospectiva UK, to form an amalgamated corporation ("Amalco"), and Pentagon acquired all of the issued and outstanding ordinary shares of Prospectiva UK (the "Prospectiva Ordinary Shares").

As consideration for the acquisition of all of the outstanding securities of Prospectiva UK, holders of Prospectiva Ordinary Shares received one (1) Resulting Issuer Share for each one (1) Prospectiva Ordinary Share held, on a post-Consolidation basis. As a result of the foregoing, Prospectiva UK and Amalco are each wholly owned subsidiaries of the Resulting Issuer, and Terra Firme Exploração Mineral Ltda., which owns a 100% interest in the Borborema Project, has become an indirect wholly owned subsidiary of the Resulting Issuer.

Prior to the completion of the Transaction, Pentagon consolidated the issued and outstanding common shares of Pentagon (the "Pentagon Shares") on the basis of one (1) post-consolidation Pentagon Share for every 5.8725 pre-consolidation Pentagon Shares (the "Consolidation") and completed the Name Change. Shareholder approval for the Consolidation and Name Change was obtained at Pentagon's annual general and special meeting of shareholders held on August 27, 2025.

Upon completion of the Transaction, the Resulting Issuer carries on the existing business of Prospectiva UK as a mineral exploration company focused on the exploration of the 100% owned Borborema Project located in the states of Pernambuco and Paraíba, in northeast Brazil (the "Borborema Project").

For further information regarding the Transaction, readers are referred to the filing statement of the Resulting Issuer dated July 31, 2026 (the "Filing Statement"), prepared in accordance with the requirements of the TSXV and available under the Resulting Issuer's SEDAR+ profile at www.sedarplus.ca.

The Offering

In connection with the Transaction, Prospectiva UK and Pentagon previously completed, through Finco, a private placement of an aggregate of 4,545,041 subscription receipts of Finco (the "Subscription Receipts") at a price of C$0.81 per Subscription Receipt for aggregate gross proceeds of $3,681,483 (the "Offering"). The Offering was comprised of a brokered private placement of 2,895,900 Subscription Receipts for gross proceeds of C$2,345,679 led by Paradigm Capital Inc., as sole agent and bookrunner (the "Agent"), and a non-brokered private placement of 1,649,141 Subscription Receipts for gross proceeds of C$1,335,804.21.

In connection with the completion of the Transaction, the escrow release conditions applicable to the Offering were satisfied and, accordingly, each Subscription Receipt was converted, without payment of additional consideration and without further action on the part of the holder, into one common share of Finco (a "Finco Share") and one common share purchase warrant of Finco (a "Finco Warrant"). Upon completion of the Transaction, each Finco Share was exchanged for one Resulting Issuer Share and each Finco Warrant was exchanged for one common share purchase warrant of the Resulting Issuer (a "Resulting Issuer Warrant"). Each Resulting Issuer Warrant is exercisable for one Resulting Issuer Share at an exercise price of C$1.13 per share for a period of twenty-four (24) months following the date of issuance, subject to adjustment in certain events.

Upon satisfaction of the escrow release conditions, the escrowed proceeds of the Offering, together with the balance of the Agent's cash commission held in escrow, were released. As consideration for its services in connection with the brokered portion of the Offering, the Agent received a cash commission of C$164,197.54 and 202,713 broker warrants of Finco, which broker warrants were exchanged for an equivalent number of common share purchase warrants of the Resulting Issuer on a one-for-one basis upon completion of the Transaction. Each such warrant is exercisable to purchase one Resulting Issuer Share at a price of C$0.81 per share for a period of twenty-four (24) months from the closing date of the brokered private placement.

The net proceeds of the Offering are expected to be used for exploration of the Borborema Project, property payments and for general corporate and working capital purposes.
