If the filing person has previously filed a statement on Schedule 13G to report the acquisition which is the subject of this Schedule 13D, and is filing this schedule because of Rule 13d-1(b)(3) or (4), check the following box ¨.

*The remainder of this cover page shall be filled out for a reporting person's initial filing on this form with respect to the subject class of securities, and for any subsequent amendment containing information which would alter the disclosures provided in a prior cover page.

The information required in the remainder of this cover page shall not be deemed to be "filed" for the purpose of Section 18 of the Securities Exchange Act of 1934 ("Act") or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

The class of equity securities to which this Statement relates is shares of common stock, par value $0.00001 per share (the "Company Shares"), of XLR Medical Corp., a Nevada Corporation (the "Company"). The principal executive offices of the Company are located at Suite 3400, 666 Burrard Street, Vancouver, British Columbia, Canada, V6C 3P6.

On September 13, 2004, the Company issued to Mr. Van Laare 850,000 Company Shares in consideration for 850,000 shares in the common stock of TSI Medical Corp. ("TSI") in connection with a merger (the "Merger") between TSI and TSI Med Acquisition Corp. ("Merger Sub"), a wholly owned subsidiary of the Company. The TSI shares exchanged by Mr. Van Laare were held by Mr. Van Laare for his own benefit and have been cancelled in connection with the Merger.

Also in connection with the Merger, the Company issued to Mr. Van Laare options to purchase 375,000 Company Shares at a price of $0.50 per share and expiring on May 31, 2009 in exchange for options issued by TSI to purchase 375,000 shares of TSI common stock at the same exercise price and expiration date. The TSI options exchanged by Mr. Van Laare were held by Mr. Van Laare for his own benefit and have been cancelled in connection with the Merger.

On September 13, 2004, TSI merged with and into Merger Sub pursuant to an Agreement and Plan of Merger (the "Merger Agreement") between the Company, Carlo Civelli, Bruno Mosimann, TSI and Merger Sub, dated effective August 12, 2004. On September 15, 2004, Merger Sub was merged with and into the Company and the Company changed its name from Relay Mines Limited to XLR Medical Corp. The purpose of the Merger was to allow the Company to acquire rights to a technology being developed by Exelar Medical Corporation, a joint venture corporation set up by TSI and Exelar Corporation, and to allow TSI to access public equity markets.

In connection with the Merger, each share of TSI common stock was exchanged for one Company Share and each option and warrant to acquire TSI common stock (the "TSI Options") was exchanged for options and warrants to acquire Company Shares on the same terms and conditions and with the same exercise price as the TSI Options. As a result, Mr. Van Laare exchanged 850,000 shares of TSI common stock and TSI Options to acquire 375,000 shares of TSI common stock at an exercise price of $0.50 per share for 850,000 Company Shares and options to acquire 375,000 Company Shares at the same exercise price. As a result of the Merger, Mr. Van Laare is now the beneficial owner, as that term is defined by section 13(d) of the Securities Exchange Act of 1934 and Regulation 13D thereto, of 5.3% of the Company's common stock.

Also in connection with the Merger, effective on September 13, 2004, Mr. Civelli resigned as President, Principal Executive Officer, Treasurer, Principal Financial Officer and as a director of the Company and Mr. Mossiman resigned as Secretary and as a director of the Company and new officers and directors were appointed as follows:

The Bylaws of the Company were amended and restated on September 12, 2004 in order to adopt a form of Bylaws consistent with those of TSI. The Company believes that the amendments to its Bylaws do not create a material impediment to any person seeking to acquire control of the Company.

Under Rule 13d-3, a beneficial owner of a security includes any person who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares: (i) voting power, which includes the power to vote, or to direct the voting of shares; and (ii) investment power, which includes the power to dispose or direct the disposition of shares. Certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by such person (and only such person) by reason of these acquisition rights. As a result, the percentage of outstanding shares of any person as shown in this table does not necessarily reflect the person's actual ownership or voting power with respect to the number of shares of common stock actually outstanding on the date of this Statement. As of September 13, 2004, there were 22,859,875 Company Shares issued and outstanding.

The number of Company Shares listed as beneficially owned by Mr. Van Laare include 850,000 Company Shares and options to acquire 375,000 Company Shares exercisable at $0.50 per share.
