Exhibit 10.1


                           MINERALS PURCHASE AGREEMENT

     This Agreement is dated effective July 1, 2005, and entered into this 24th
Day of June, 2005, by and between Zephyr Bay Sports Partners, LLC., a Colorado
Limited Liability Company (the "Seller") and Colorado Oil and Gas, Inc., a
Colorado Corporation (the "Buyer").

                                    RECITALS

I.   Seller is owned by William W. Stewart, President, Director and Shareholder
     of Buyer. Seller owns a pool of minority mineral interests in certain oil
     and gas leases located in Colorado, Wyoming, Texas and Oklahoma and has
     offered to sell these interests to the Buyer for $200,000 (the "Purchase
     Price") in the form of a Secured Promissory Note. The leases and interests
     are set forth in detail in Schedule A, attached hereto and incorporated
     herein by reference (the "Mineral Interests.")

II.  Buyer is a majority owned subsidiary of Arete Industries, Inc., a Colorado
     corporation that is publicly traded on the NASDAQ over the counter market.
     Buyer is a development stage company seeking to acquire small interests in
     oil and gas leases including passive investments as well as developmental
     properties. Buyer's board of directors has authorized the Buyer to engage
     in the proposed transaction set forth in this Agreement, as follows:

                                    AGREEMENT

1.   Seller agrees to sell to Buyer and the Buyer agrees to buy the Mineral
     Interests for the Purchase Price on the terms set forth below.

2.   Seller grants, bargains and conveys the Mineral Interests described in
     Schedule A to Buyer free and clear of any and all encumbrances, liens,
     claims and judgments, for consideration payment of the Purchase Price of
     $200,000 subject to adjustment, as provided in Paragraph 4, below.

3.   The Purchase Price will be paid with a Secured Promissory Note in favor of
     Seller in the amount of the Purchase Price, plus 12% simple interest,
     payable interest only on a monthly basis for 12 months beginning one month
     following the Effective Date. Interest payments may deferred if the Buyer
     does not have sufficient revenue to make payments for up to 120 days before
     the Secured Promissory Note will be deemed in default. There will be a
     balloon payment of all principal amounts and accrued interest due 12 months
     from the Effective Date (the "Due Date.") There will be no prepayment
     penalty in the event of partial payments of principal during the term of
     the Note. The Secured Promissory Note shall be secured exclusively by a
     first lien or mortgage on the Mineral Rights themselves. In the event of
     dissolution or liquidation of the Buyer during the term of the Note, such
     event would be deemed an event of default and the Mineral Interests would
     be reconveyed to Seller in cancellation of the indebtedness,

     EXCEPT, that in the event the Buyer makes any principal payments in excess
     of 30% of the Purchase Price during the term of the Secured Promissory
     Note, the Buyer shall have the option, upon such event of default, to sell
     the Mineral Interests to a third party or to the Seller (who shall have a
     first right of refusal to match any bona-fide third-party offer). If Buyer
     has made such principal payments and elects not to sell the Mineral
     Interests as provided in the preceding sentence, then Seller shall repay
     Buyer any amount of such principal payments, less any accrued and unpaid
     interest on the Secured Promissory Note as of the date of default.

4.   The Purchase Price shall be subject to adjustment to actual market value as
     determined by a third party appraiser selected by mutual agreement of the
     Seller and Buyer (with Mr. Stewart abstaining from any board of directors'
     vote in making such selection.) The appraisers' valuation shall be binding
     on both Parties hereto. Such adjustment shall be to not less than $150,000
     nor more than $250,000 and the original principal amount of the Secured
     Promissory Note and Purchase Price shall be retroactively restated to such
     amount. In the event that the appraised value is less than $150,000, the
     Buyer may reject the purchase without penalty or obligation to the Seller
     whatsoever. In the event that the appraised value is greater than $250,000,
     the Purchase Price shall be reset to $250,000 without any further or other
     obligation arising from such circumstance to the Seller other than the
     referenced interest only payments of the Secured Promissory Note, and the
     principal amount on the Due Date.

5.   Buyer may sell all or any portion of the Mineral Interests to a third party
     for cash consideration at any time, PROVIDED that, Seller shall have a
     first right to match any bona-fide third party offer within 15 days of
     receipt of written notice from Buyer of such bona-fide third party offer.
     Buyer may also refinance the Mineral Interests at any time provided that
     Seller receives full payment of all outstanding principal and accrued
     interest at the time of closing of such refinance. Buyer may not pledge any
     or all its right title and interest in the Mineral Interests except subject
     to the lien of the Seller evidenced by this Agreement, and any subsequent
     security interests recorded subsequent to the date of this Agreement, nor
     without first obtaining a written subordination agreement, subordinating
     the lien of the Seller to the Pledgee, from the Seller.

6.   Seller shall provide Buyer with Assignment Agreements for the Mineral
     Interests in such form as is required to properly record such Assignment of
     the Mineral Interests in the proper county office in each county and state
     in which the Mineral Interests are located on or before the Effective Date,
     or within a reasonable time thereafter, with the consent of the Buyer,
     which consent shall not be unreasonably withheld. Buyer shall execute and
     deliver any security agreements and financing statements, or Mineral
     Interest Mortgages, necessary to perfect Seller's security interest in the
     Mineral Interests, through proper recording in appropriate county offices
     where the Mineral Interests are located. In the event that circumstances
     prevent the proper recording of Mineral Interest Assignments or perfection
     of security interests as the means for carrying out the provisions of this
     Agreement, Seller shall provide the Parties with appropriate legal
     agreements binding the operator or manager of the total pool of mineral
     interests in which the Mineral Interests are included, sufficient to
     transfer title to the Mineral Interests to the Buyer and perfect the
     Seller's security interest under the Secured Promissory Note.

7.   In no event shall either Party cause any liens or encumbrances to attach to
     the Mineral Interests prior to or subsequent to the Effective Date of this
     Agreement except with the knowledge and consent of the other Party, and the
     Parties hereto agree to indemnify and hold harmless, the other from and
     against any such claims, liens, encumbrances, and agree to sue and defend
     any claim or cause of action which may give rise to an encumbrance or
     imposition of the lien of any judgment, claim, assessment or encumbrance
     upon the Mineral Interests at their sole cost and expense.

8.   This Agreement shall be binding upon the Parties, their respective
     officers, directors, managers, members, shareholders, and their successors,
     trustees, receivers and permitted assigns. Seller may not assign the
     Secured Promissory Note, nor any security interest arising therefrom in
     whole or in part without the express written permission of the Buyer. This
     Agreement will survive and be deemed not to have merged into any Assignment
     Agreements as to the Mineral Interests, as well as any Mortgage or
     Collateral Agreement providing security to the Secured Promissory Note. In
     the event of any real or apparent conflict of terms between the various
     agreements and undertakings described herein, the more specific term of one
     such document will govern over a general term in any of the others. If any
     of the terms and conditions of this Agreement shall be deemed unenforceable
     by operation of statute, by the common law, or by any judgment or decree of
     court, such event shall not affect the enforceability of any other term of
     provision herein, or in any of the collateral documents described herein.

9.   Each Party agrees to execute such other and further documents to carry out
     the purpose and intent of this Agreement and of the collateral agreements
     and undertakings contemplated herein, including any documents required by
     way of further assurances of any Party reasonably required in furtherance
     of the purposes stated herein.

10.  Notices: Any notices required to be given, shall be given for any purpose
     to the last known address of the Party to receive the notice: if by first
     class mail, three days after posting in the US Mail shall be the effective
     date of the notice, or by courier if a delivery receipt is provided, the
     date delivered by the courier to the office address of the recipient; or if
     by facsimile, the latter of the date of the facsimile or the date that a
     confirmed copy was posted in the US Mail. No notices by email shall be
     deemed given unless followed with a conformed copy, and then shall be
     effective three days after posting the conformed copy in the US Mail.
