We plan to use Ultra’s US $6M investment in Appia Brasil to continue drilling to expand the carbonite high grade RE mineralization with a view to completing a mineral resource estimate in the following months. The funds will also help us advance the PCH Ionic Clay project to the prefeasibility study stage. PCH is a unique project because it contains high grade rare earths in both ionic clay and carbonatitic breccia.”

Pursuant to the Transaction:

1. Ultra acquired a 45% interest in Appia Brasil from Appia and a 5% interest from Antonio for a 50% interest in Appia Brasil with Appia now holding a 25% interest and Antonio now holding a 25% interest in Appia Brasil.
2. Ultra advanced US $3 million to Appia Brasil and will advance a further US $3 million to Appia Brasil within three months or within 5 Business Days following a request from the Management Committee (as defined below) to advance the funds. The aggregate of US $6 million will be used to fund exploration on the Property, prepare a mineral resource estimate in respect of the hard rock carbonatitic breccia deposit prepared in compliance with the standards set out in NI 43-101 and advance the Property to the point of a prefeasibility study.
3. Each WC Unit consists of one (1) common share of the Company priced at $0.50 per common share and one-half (0.5) of a common share purchase warrant. Each full warrant entitles the holder to purchase one (1) common share at a price of $0.70 per WC Warrant Share until October 31, 2027.

4. Appia issued 1 million common shares of Appia to Beko and was released from any further obligations under the existing Quotaholders Agreement dated July 20, 2023 among Appia, Beko and Antonio. Appia has a right of first refusal in respect of the 1% NSR on the Property granted to Beko pursuant to the Quotaholders Agreement. If Appia exercises its right of first refusal and acquires the 1% NSR, Ultra will have a right of first refusal with respect to any subsequent sale of the 1% NSR by Appia.

Mr. Don Hains, P.Geo, Consulting Geologist, will be the fifth member of the Management Committee and in the event of a tie vote, will have a vote to break the tie.
