Item 1. Security and Issuer.

This Schedule 13D relates to shares of common stock of Premier Royalty Inc. (the “Common Shares”). The address of the Premier Royalty Inc.’s principal executive office is 1100 Russell Street, Unit #6, Thunder Bay, Ontario, Canada P7B 5N2.

Item 2. Identity and Background.

(a)-(c) Premier Gold Mines Limited (“Premier Gold”) is a publicly traded corporation in Canada incorporated under the laws of the province of Ontario, Canada. Its principal business address is Suite 200, 1100 Russell Street, Thunder Bay, Ontario, Canada P7B 5N2. Premier Gold’s principal business is exploration and development of gold mining projects. The name, business address and present principal occupation of each executive officer and director of Premier Gold is set forth on Schedule I hereto.

(d) During the last five years, neither Premier Gold, nor to Premier Gold’s knowledge, any of its executive officers or directors named on Schedule I, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, neither Premier Gold, nor to Premier Gold’s knowledge, any of its executive officers or directors named on Schedule I, was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was, or is, subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) The citizenship of each executive officer and director of Premier Gold is set forth on Schedule I.

Item 3. Source and Amount of Funds or Other Consideration.

On December 4, 2012, Premier Gold acquired 33,655,821 Common Shares in connection with a business combination (the “Business Combination”) of Premier Gold’s subsidiary Premier Royalty Corporation and Bridgeport Ventures Inc., and Bridgeport Ventures Inc. changed its name to Premier Royalty Inc. Prior to the Business Combination, Premier Gold owned 33,655,821 common shares of Premier Royalty Corporation. The common shares of Premier Royalty Corporation were exchanged for Common Shares of Premier Royalty Inc. on a one-for-one basis resulting in Premier Royalty Corporation becoming a wholly-owned subsidiary of Premier Royalty Inc.

Item 4. Purpose of Transaction.

The Common Shares were acquired in connection with the Business Combination for investment purposes. Although Premier Gold does not have any specific plans or proposals to acquire or dispose of the Common Shares, it may from time to time acquire additional Common Shares or dispose of any or all of its Common Shares, depending upon on market conditions and any other relevant factors.

As repayment of the outstanding balance of a convertible bridge loan facility with Premier Royalty Corporation, and in connection with the Business Combination, Premier Royalty Corporation issued to Premier Gold (i) 14,688,471 common shares which were exchanged on a one-for-one basis for Common Shares of Premier Royalty Inc., (ii) warrants exercisable to acquire 5,508,176 Common Shares

of Premier Royalty Inc. at a price of $2.00 per Common Share until December 4, 2016, subject to early expiry, and (iii) warrants exercisable to acquire 1,457,500 Common Shares of Premier Royalty Inc. at a price of $2.00 per Common Share until October 7, 2014. Also in connection with the Business Combination, convertible debentures previously issued by Premier Royalty Corporation were mandatorily converted and, in connection with such conversion, Ewan Downie, the President, Chief Executive Officer and Director of Premier Gold, received (x) 369,041 common shares of Premier Royalty Corporation, which were exchanged on a one-for-one basis for Common Shares of Premier Royalty Inc., and (y) warrants exerciseable to acquire 138,390 Common Shares of Premier Royalty Inc. at a price of $2.00 per Common Share until December 4, 2016, exerciseable after June 4, 2013 and subject to early expiry.

Pursuant to the Business Combination, all existing directors of Bridgeport Ventures Inc. resigned, other than Hugh Snyder and Shastri Ramnath, who are continuing as directors of Premier Royalty Inc. Ewan Downie, Abraham Drost, George Faught, Steven Filipovic, Howard Katz and Julie Lassonde have been appointed as directors of Premier Royalty Inc.

Except as disclosed above, Premier Gold does not have any plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D. Premier Gold may, from time to time, review or reconsider its position and/or change its purpose and/or formulate plans or proposals thereto.

Item 5. Interest in Securities of the Issuer.

(a) Premier Gold is the beneficial owner of 33,655,821 Common Shares, representing 53.49% of the outstanding Common Shares of Premier Royalty Inc.

Ewan Downie beneficially owns 369,041 Common Shares as disclosed in Item 4, and further holds options to purchase 400,000 Common Shares, 133,333 of which are currently vested. An additional 133,333 of such options will vest in September 2013, and the remaining options will vest in June 2014. The options have an exercise price of $2.37 per Common Share and expire on December 11, 2017. Accordingly, Mr. Downie is the beneficial owner of 502,374 Common Shares, representing approximately 0.80% of the Common Shares of Premier Royalty Inc.

Steven Filipovic holds a vested option to purchase 150,000 Common Shares at an exercise price of $2.37 per Common Share. Such options expire on December 11, 2017. Accordingly, Mr. Filipovic is the beneficial owner of approximately 0.24% of the Common Shares of Premier Royalty Inc.

Except as disclosed above, to Premier Gold’s knowledge, no Common Shares are beneficially owned by any of the persons listed on Schedule I.

(b) Premier Gold has the sole power to vote or to direct to vote, and the sole power to dispose of or to direct the disposition of, 33,655,821 Common Shares of Premier Royalty Inc. Except as disclosed in Items 4 and 5, to Premier Gold’s knowledge, none of the persons listed on Schedule I have sole or shared power to vote or to direct to vote, to dispose of or to direct the disposition of any Common Shares.

(c) On December 4, 2012, Premier Gold acquired 33,655,821 Common Shares pursuant to the Business Combination described in Items 3 and 4 above. Except as disclosed in Item 4, neither Premier Gold, nor to Premier Gold’s knowledge, any person named on Schedule I, has effected any transaction in the Common Shares during the past 60 days.

(d) Except as disclosed above and in Items 3, 4 hereto, neither Premier Gold nor, to Premier Gold’s knowledge, any person named on Schedule I, has the right to receive or power to direct the receipt of dividends from, or proceeds from the sale of, the Common Shares.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Pursuant to an escrow agreement dated December 4, 2012 among Premier Gold, Premier Royalty Inc. and Valiant Trust Company, all of the Common Shares and warrants to purchase Common Shares owned by Premier Gold are subject to escrow, one-quarter of which were immediately released from escrow on December 4, 2012. One-third of the balance will be released from escrow every six months over an 18-month period. In the event Premier Royalty Inc.’s market capitalization is greater than $100 million for five trading days after the Common Shares begin trading on the Toronto Stock Exchange under the symbol “NSR”, the Toronto Stock Exchange may permit the early release from escrow of the Common Shares and warrants to purchase Common Shares owned by Premier Gold.

Except as disclosed above, in Items 3, 4, and 5 hereto and in the agreements incorporated herein by reference and set forth as exhibits hereto, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between any of the persons named in Item 2 and any person with respect to the securities of Premier Royalty Inc., including, without limitation, the transfer or voting of any of the securities, finders fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses or the giving or withholding of proxies, the occurrence of which would give another person voting or investment power over the securities of Premier Royalty Inc.
