Item 1. Security and Issuer.

This statement on Schedule 13D is hereby amended (this “Schedule 13D”) relates to:

	(1)	The common shares (“Common Shares”), of Jaguar Mining Inc. (the “Issuer”), a corporation organized under the laws of Ontario, Canada.

	(2)	Those certain convertible senior secured debentures (the “Debentures”) of the Issuer, issued October 27, 2015. The Debentures are convertible into Common Shares at a ratio of 1 Common Share per C$0.15 principal amount of Debenture converted.

The principal executive offices of the Issuer are located at 67 Yonge Street, Suite 1203, Toronto, ON M5E 1J8, Canada. This Schedule 13D amends and supplements the report previously filed by the Reporting Persons on May 2, 2014 (the “2014 Filing”).

Information contained in this Schedule 13D with respect to each Reporting Person and, if applicable, its executive officers, directors and controlling persons, is given solely by such Reporting Person, and no other Reporting Person has responsibility for the accuracy or completeness of information supplied by such other Reporting Person.

Except as set forth herein, the 2014 Filing is unmodified.

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

Item 3 of the 2014 Filing is hereby amended and supplemented by adding the following information:

Final share allocations in connection with the Plan resulted in an increase in OMF’s Common Share allocation thereunder from 36,044,388 Common Shares to 36,045,291 Common Shares, an increase of 903 Common Shares.

On October 27, 2015, OMF acquired Debentures in an aggregate principal amount of $5,350,000 for a purchase price of $5,350,000. OMF’s acquisition of the Debentures was funded by cash on hand.

Item 4. Purpose of Transaction.

This Item 4 is amended and restated in its entirety as follows:

The Common Shares held of record by OMF were acquired in connection with the restructuring of the Issuer in accordance with the Plan and are held for investment purposes.

The Issuer issued the Debentures to raise working capital. OMF acquired the Debentures for investment purposes.

The Reporting Persons intend to review on a continuing basis OMF’s investment in the Issuer. As a result of the Reporting Persons’ continuous review and evaluation of the business of the Issuer, the Reporting Persons may communicate with the board of the Issuer, members of management and/or other shareholders from time to time with respect to operational, strategic, financial or governance matters or otherwise work with management and the board with a view to maximizing shareholder value. The Reporting Persons may seek to sell or otherwise dispose of some or all of the Issuer’s securities (which may include, but is not limited to, transferring some or all of such securities to its affiliates or distributing some or all of such securities to such Reporting Person’s respective partners or members, as applicable) from time to time, and/or may seek to acquire additional securities of the Issuer (which may include rights or securities exercisable or convertible into securities of the Issuer) from time to time, in each case, in open market or private transactions, block sales or otherwise. Any transaction that the Reporting Persons may pursue may be made at any time and from time to time without prior notice and will depend on a variety of factors, including, without limitation, the price and availability of the Issuer’s securities, subsequent developments affecting the Issuer, the Issuer’s business and the Issuer’s prospects, other investment and business opportunities available to the Reporting Persons, general industry and economic conditions, the securities markets in general, tax considerations and other factors deemed relevant by the Reporting Persons.

CUSIP No. 47009M103		13D/A		Page 6 of 7

Except as described in this Item 4 of this Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, although the Reporting Persons, at any time and from time to time, may review, reconsider and change their position and/or change their purpose and/or develop such plans and may seek to influence management or the board of the Issuer with respect to the business and affairs of the Issuer, and may from time to time consider pursuing or proposing any such transactions and, in connection therewith, may discuss, evaluate and/or pursue any such transactions with advisors, the Issuer or other persons.

Item 5. Interest in Securities of the Issuer.

Items 5(a) and 5(b) of the 2014 Filing are hereby amended and supplemented by adding the following information:

OMF owns Debentures in an aggregate principal amount of $5,350,000. In the event that all Debentures owned by OMF were converted, OMF would have ownership and control of an additional 46,979,276 Common Shares, for a total of 83,024,567 Common Shares (representing approximately 52.5% of outstanding Common Shares on a post-exercise basis, assuming no conversions by other Debenture holders).7

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons (other than OMF, to the extent it directly holds Debentures reported on this Schedule 13D) is the beneficial owner of the Debentures referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and such beneficial ownership is expressly disclaimed. Each Reporting Person expressly disclaims any assertion or presumption that it and the other persons on whose behalf this statement is filed constitute a “group.”

(c) Except as set forth herein, none of the Reporting Persons have engaged in any transactions with respect to the Issuer’s Common Shares during the past sixty days.
