EARLY WARNING PRESS RELEASE

Erich Kopple and Jordan Greenhut, as trustees for the Robert and Carole Kopple Grandchildren's Trust (the acquiror), dated Dec. 28, 2007, make the following disclosure regarding its World Copper Ltd. holding, in accordance with National Instrument 62-103, The Early Warning System and Related Take-Over Bid and Insider Reporting, and National Instrument 62-104, Take-Over Bids and Issuer Bids (NI 62-104).

The acquiror advises that on May 20, 2022, it acquired ownership of and control over 7,731,286 common shares in the capital of World Copper at a deemed issuance price of 40 cents per acquired share. The acquisition was made pursuant to the buyback by World Copper of a 1-per-cent net smelter return (NSR) royalty on future production from World Copper's Zonia project for the purchase price of $3,092,514, which purchase price was paid by World Copper through the issuance of the acquired shares to the acquiror. The acquisition did not take place on a stock exchange or other market that represents a published market for securities.

Immediately before the completion of the acquisition, the acquiror owned and had control and direction over an aggregate of 4,283,150 common shares in the capital of World Copper and 1,204,771 common share purchase warrants, representing approximately 4.50 per cent of the issued and outstanding common shares in the capital of World Copper on a non-diluted basis (5.69 per cent on a partially diluted basis). After the acquisition, the acquiror owned and had control and direction over an aggregate of 12,014,436 common shares, representing approximately 9.61 per cent of the issued and outstanding common shares on a non-diluted basis (10.47 per cent on a partially diluted basis), based on the current number of outstanding common shares. The change in the acquiror's security holding percentage of common shares is an increase of approximately 5.11 per cent (4.78 per cent on a partially diluted basis).

The acquiror acquired the shares pursuant to World Copper's buyback of the royalty. However, the acquiror will review its holdings from time to time and may, in the future, increase or decrease its ownership or control over securities of World Copper as circumstances dictate.

The acquiror will file an early warning report under World Copper's profile on SEDAR. A copy of the early warning report can also be obtained from 1520 Tower Grove Dr., Beverly Hills, Calif., 90210, attention Kathleen Kuhn (phone: 310-860-9797).
