  index shall be the index published for April 2015. However, in no case will
  the Advance Royalty drop below the Advance Royalty base amount of $50,000.
                 Advance
  Royalties shall be paid on or before the date due. Advance Royalties paid hereunder
  shall be credited against and fully recoupable from any and all Production Royalty
  that may accrue under Section 2.2, regardless of whether such Production Royalty
  accrues or is made in the same or any subsequent year to the year of payment
  of the Advance Royalties.

2.2        Production
  Royalty.

(a)      Percentage and Calculation.Subject to applicable credits and adjustments, Lessee, in accordance with
  its usual practice, shall pay to Lessor a production royalty (the “Production
  Royalty”) equal to the applicable percentage of Net Value as defined,
  calculated and paid as set forth in Exhibit B, attached hereto and by this reference
  made a part hereof. Said percentages shall be as follows:

---

| | Gold Price                  | Royalty Percentage
| | --------------------------- | ------------------
| | $275 or less per ounce      | 2.5%              
| | $275.01 to $ 375  per ounce | 3.0%              
| | $375.01 to $ 475  per ounce | 4.0%              
| | $475.01 or greater          | 5.0%              

(b)      Option to Reduce Production
  Royalty.At any time during the term of this Lease and as to all Production
  Royalty payments not yet paid, Lessee shall have the right to reduce the Production
  Royalty by purchasing a portion of the Lessors Production Royalty such that
  the Lessor retains a minimum 2% Production Royalty. The purchase price of the
  Production Royalty shall be $1,000,000 US for each 1% Production Royalty,
  $500,000 for each 0.5% Production Royalty, and $250,000 for each 0.25%
  Production Royalty. Such a Production Royalty buy down may take place all at
  one time or piecemeal.
                 The
  right to purchase the said Production Royalty interest shall be exercised by
  Lessee providing the Lessor with notice of the purchase accompanied by payment
  in full for the amount of the Production Royalty interest being purchased.
                 If
  only a portion of the Production Royalty is purchased, then in the event of
  changes in the gold price the Lessor shall retain the remaining unpurchased
  Production Royalty percentage points on the sliding scale Production Royalty,
  as outlined in Section 2.2(a) herein.

Example:Example: Gold is selling at $370.00 an
  ounce. Lessee purchases 1.0% of the Production Royalty for 1 million dollars
  reducing the Production Royalty from 3.0% to 2.0% . Later Gold rises to $500
  an ounce and the effective Production Royalty becomes 4.0% . Gold then falls
  to $250.00 an ounce. The effective Production Royalty would be 2.0% not 1.5%
  .

(c)      Disputes.Lessor
  shall be deemed to have waived any right it may have had to dispute any payment
  of Production Royalty unless Lessor notifies Lessee in writing of such dispute
  within six (6) months after the date of Lessee’s payment, providing reasonable
  detail as to the nature of the dispute.

III.        OPERATIONS

3.1        No Implied
  Covenants.

  obligations of Lessee under this Agreement exclude and negate, any express or
  implied covenant or duty of Lessee to conduct any activity upon or for the benefit
  of the Property, including without limitation any activities related to the
  exploration, development or mining of the Property. Whether or not any such
  exploration, development, mining or other activities shall at any time (including,
  without limitation, during the primary term or any extended term of this Agreement)

VI.        Termination

6.1        By
  Lessor.

At the election of Lessor, the failure of Lessee to perform
  any material obligation according to the terms or provisions of this Agreement,
  which substantially affect the rights of the Lessor under this Agreement, shall
  constitute an event of default. Upon an event of default, Lessor shall give
  to Lessee written notice of default, specifying in reasonable detail the particular
  default or defaults relied on by Lessor. Lessee shall have thirty (30) days
  after receipt of Lessor’s notice in which to contest, cure, or commence
  to cure (and diligently thereafter proceed to cure) the alleged default or defaults.
  If Lessee contests that default occurred, it shall so advise Lessor in writing
  within thirty (30) days after receipt of Lessor’s notice. If, within fifteen
  (15) days after Lessor’s receipt of Lessee’s notice the Parties
  have not resolved the dispute by mutual agreement, the issue of default may
  be submitted to a court of competent jurisdiction, and Lessee shall not be deemed
  to be in default until the matter shall have been determined finally by the
  court and all appeals have been waived or exhausted and all periods for appeal
  have expired. If the judicial process results in a final finding of default,
  Lessee shall have thirty (30) days thereafter in which to cure or commence to
  cure (and diligently thereafter proceed to cure) the default. Upon Lessee’s
  failure to cure or commence to cure the default within the time periods allowed
  above, Lessor may declare, by written notice to Lessee, a termination of this
  Agreement. Lessor’s sole remedy shall be the recovery of actual compensatory
  damages, including attorneys fees.

6.2        By
  Lessee.

Lessee shall have the right, at any time and from time to
  time, to surrender and terminate this Agreement by providing to Lessor written
  notice of such surrender. The termination

shall take effect upon the date notice is given. Upon such
  termination, Lessee’s right, title, interest and obligations with respect
  to the Property shall terminate, except as provided in this Agreement to the
  contrary. All Payments which have accrued as of the date of termination shall
  be payable to Lessor by Lessee. Partial termination of select claims is not
  allowed without Lessors written consent.

6.3        Removal
  of Property.

Lessee shall have the right, but not the obligation, for a
  period of one (1) year after expiration, surrender, or termination of this Agreement,
  to enter upon and remove from the Property any or all machinery, equipment,
  fixtures, buildings, improvements, concentrates, ore, tailings, residue and
  personal property of every kind and description erected or placed upon or extracted
  from the Property by Lessee. Any such property not removed by Lessee from the

PRODUCTION ROYALTY

1        Production
  Royalty.

The Production Royalty provided for in Section 2.2 of the
  Agreement and payable to Lessor shall be based upon: (a) the value of dor ́e
  produced from ores and minerals mined from the Property, determined at the Property
  or at such other facility producing such dor ́e, sold or deemed sold, determined
  by reference to published prices for refined gold and silver and other Precious
  Metals (as hereinafter defined), and (b) the value of all other Products produced
  from ores and minerals mined from the Property, determined at the Property or
  at such other facility producing such Product, sold or deemed sold, determined
  by reference to published prices for such “Other Products” all as
  hereinafter provided. It is acknowledged that it will be necessary to process,
  treat or upgrade Precious Metals or Other Products at a location or locations
  not on the Property before they are sold or deemed to be sold; and that to determine
  the value of such Precious Metals or Other Products of the Property or other
  facility producing dor ́e or Other Products, all costs incurred or deemed
  to be incurred by Miranda in paying the Production Royalty with respect to the
  transporting, processing, treatment or upgrading of the Precious Metals or Other
  Products after they have been processed shall be deducted from the proceeds
  received or deemed to be received by Miranda as hereinafter set forth.
                 Miranda
  shall pay to Lessor a Production Royalty as set forth in Section 2.2 of the
  Agreement as a percentage of the Net Value (as hereinafter defined) of Precious
  Metals or Other Products mined, removed and sold (or deemed sold as hereinafter
  described) from the Property. For purposes of this Agreement, the term “Precious
  Metals” shall mean gold, silver, platinum and palladium and “Other
  Products” shall mean all other metallic and non-metallic minerals of every
  kind except: (a) Precious Metals and (b) oil, gas, casinghead gas and associated
  liquid and gaseous hydrocarbon substances. The Production Royalty shall run
  with the land described as the Property. The Production Royalty shall specifically
  apply to unpatented lode mining claims that are a part of the Property and to
  any relocation or amendment thereof, to any patent issued covering such land
  and to any other right, title or interest acquired by, for, or on behalf of
  Miranda with respect to such land. The obligation to pay the Production Royalty
  shall accrue upon and not before: (a) the outturn of refined Precious Metals
  meeting the requirements of the specified published price and a credit for which
  is made to Miranda’s account (or to a third-party account for the benefit
  of Miranda) or (b) the sale of unrefined metals, dor ́e, concentrates,
  ores or Other Products, as hereinafter

---

provided, whichever is sooner.

2        Net Value Definition.

As used herein, “Net Value” means the Gross Value
  of Precious Metals or Other Products, less all costs, charges and expenses paid
  or incurred by Miranda after production of dor ́e, or, in the case of Other
  Products, after production of concentrates, whether at the Property or elsewhere
  with respect to the transportation, processing, treatment or upgrading of the
  dor ́e or concentrates such costs, charges and expenses to include, without
  limitation, the following: 
                 
  (a) charges for treatment in the smelting and refining processes (including
  handling, processing, interest and provisional settlement fees, sampling, assaying
  and representation costs, penalties and other processor deductions); 
                 
  (b) actual costs of transportation (including freight, insurance, security,
  transaction taxes, handling, port, demurrage, delay, and forwarding expenses
  incurred by reason of or in the course of such transportation) of dor ́e
  or concentrates from the Property or other facility producing dor ́e or
  concentrates to the place of additional treatment and to the place of sale;
  
                 
  (c) actual sales and brokerage costs of Precious Metals or Other Products for
  which the Production Royalty is based on proceeds received by the Lessee as
  hereinafter provided in Section 3(d) below, and an allowance for reasonable
  sales and brokerage costs for refined Precious Metals subject to the Production
  Royalty hereinafter provided in Sections 3(a), (b) and (c) below;
                 
  (d) all royalties payable to any governmental agency, and sales, use, severance,
  net proceeds of mine, ad valorem taxes applicable under state, federal or local
  law and any other tax or governmental levy or fee on or measured by mineral
  production from the Property (other than taxes based on income).

3Gross
  Value Definition.

“Gross Value” shall have the following meaning:
                 (a)
  If Miranda causes refined gold which meets or exceeds generally accepted commercial
  standards for the sale of refined gold (it being understood that the specifications
  for refined gold published by the London Metal Exchange presently meet such
  standards) to be produced from ores and minerals mined from the Property and,
  if Section 3(d) shall not be applicable, for purposes of determining the Production
  Royalty, the refined gold shall be deemed to have been sold at the Monthly Average
  Gold Price for the month in which it was refined, and the Gross Value shall
  be determined by multiplying Gold Production during the calendar month by the
  Monthly Average Gold Price. As used in this Agreement, “Gold Production”
  means the quantity of refined gold in troy ounces outturned to Miranda’s
  pool account (or to a third-party account for the benefit of Miranda) by an
  independent third-party refinery from ores and minerals mined from the Property
  on either a provisional or final settlement basis

---

each calendar month. As used herein, “Monthly Average
  Gold Price” means the average London Bullion Market Association P.M. Gold
  Fix for a troy ounce of refined gold of a quality that is equal to or less than
  the quality of refined gold produced from the ores and minerals and meeting
  the standards applicable to the refined gold for which the Gross Value is to
  be determined hereunder, calculated by dividing the sum of all such prices reported
  for the month in question by the number of days for which such prices were reported.
                 In
  the event that the London Bullion Market Association P.M. Gold Fix ceases or
  quotes prices for refined gold of a quality that is greater than the quality
  of refined gold for which the Gross Value is being determined hereunder, all
  such references shall be replaced with references to prices of gold of a comparable
  quality for immediate delivery in the most nearly comparable established market
  selected by Miranda as such prices are published in “Metals Week”
  or a similar publication.
                 (b)
  If Miranda causes refined silver which meets or exceeds generally accepted commercial
  standards for the sale of refined silver (it being understood that the specifications
  for refined silver published by Handy & Harman presently meet such standards)
  to be produced from ores and minerals mined from the Property and, if Section
  3(d) shall not be applicable, for purposes of determining the Production Royalty,
  the refined silver shall be deemed to have been sold at the Monthly Average
  Silver Price for the month in which it was refined, and the Gross Value shall
  be determined by multiplying Silver Production during the calendar month by
  the Monthly Average Silver Price. As used herein, “Silver Production”
  means the quantity of refined silver in troy ounces outturned to Miranda’s
  pool account (or to a third-party account for the benefit of Miranda) by an
  independent third-party refinery from ores and minerals mined from the Property
  on either a provisional or final settlement basis each calendar month. As used
  herein, “Monthly Average Silver Price” means the average New York
  Silver Price as published daily by Handy & Harman for a troy ounce of refined
  silver of a quality that is equal to or less than the quality of refined silver
  produced from the ores and minerals meeting the standards applicable to the
  refined silver for which the Gross Value is to be determined hereunder, calculated
  by dividing the sum of all such prices reported for the calendar month in question
  by the number of days for which such prices were reported.
                 In
  the event that the Handy & Harman quotation ceases or quotes prices for
  refined silver of a quality that is greater than the quality of refined silver
  for which the Gross Value is being determined hereunder, all such references
  shall be replaced with references to prices of silver of a comparable quality
  for immediate delivery in the most nearly comparable established market selected
  by Miranda as published in “Metals Week” or a similar publication.
                 (c)
  If Miranda causes refined or processed Precious Metals, other than refined gold
  and refined silver, which meets or exceeds commercial standards for the sale
  of such Precious Metals, or refined or processed Other Products, to be produced
  from ores and minerals mined from the Property, and if Section 3(d) shall not
  be applicable, for purposes of determining the Gross Value of such Precious
  Metals (other than refined gold and refined silver) or refined or processed
  Other Products hereunder the same shall be deemed to have been sold at the Monthly
  Average Price for the same for the month in which it was refined, and the Gross

---

Value shall be determined by multiplying Production of the
  same during the calendar month by the Monthly Average Price for the same. As
  used herein, Production means the quantity of such Precious Metals (other than
  refined gold and refined silver) or refined or processed Other Products in standard
  commercial units outturned to Miranda’s pool account (or to a third-party
  account for the benefit of Miranda by an independent third-party refinery from
  ores and minerals mined from the Property on either a provisional or final settlement
  basis each calendar month. As used herein, “Monthly Average Metal Price”
  means the price for each such standard commercial unit of such Precious Metals
  (other than refined gold and refined silver) or refined or processed Other Products
  for immediate delivery in an established market selected by Miranda as such
  price is published in “Metals Week” or a similar publication.
                 (d)
  In the event Miranda sells raw ores of Precious Metals or Other Products or
  concentrates or dor ́e produced from such ores and minerals mined from
  the Property, then the Gross Value shall be calculated as set forth in Section
  3(a), (b) and (c), except that Gold Production, Silver Production or other Production
  shall, in each case, be equal to the amount of gold, silver, other Precious
  Metals and Other Products contained in such raw ores, concentrates or dor ́e
  sold in the specified month multiplied by (i) the recovery rate for such gold,
  silver, other Precious Metals and Other Products contractually determined between
  Miranda and a third party processor or (ii) if there is not a specifically contracted
  recovery rate, then by an assumed recovery rate equal to the average actual
  recovery rate experienced by Miranda from the beneficiation of such ores and
  minerals for such gold, silver, other Precious Metals and Other Products for
  the latest calendar quarter ended prior to such month. In the event that such
  ores and minerals have not been so beneficiated by Miranda during any such calendar
  quarter, the recovery rate shall be the actual recovery rate experienced by
  the purchaser of such ores and minerals determined in good faith by Miranda.
                 (e)
  Where outturn of Precious Metals or Other Products is made by an independent
  third-party refinery on a provisional basis, the Gross Value shall be based
  upon the amount of such provisional settlement, but shall be adjusted in subsequent
  statements to account for the amount of such Precious Metals or Other Products
  established by final settlement by such refinery.

4        Forward Sales.

Lessor acknowledges that Miranda shall have the right to market

  sales, futures trading or commodity options trading, and any other price hedging,
