AND:

             MAGELLAN GOLD CORP. (TO BE RENAMED "CENTRASIA MINING CORP."), a
             company having an office at 300 - 1055 West Hastings Street,

or before the closing (the "Effective  Date") of the RTO, Baradero will purchase
the Debt from the Creditor in  consideration  for the repayment of the Principal
Amount in common shares of Baradero (the  "Baradero  Shares") and the payment of
the Interest  Amount in cash, in the amounts as set out in Schedule "A" attached
hereto.

D.        Each Baradero Share will be issued at a deemed price of Cdn$0.20.

E.        Baradero's  obligation to complete the  transactions  contemplated  by
this Agreement will be subject to the concurrent completion of the RTO.

F.        The Creditor is prepared to accept the issuance of the Baradero Shares
in full satisfaction of the Principal Amount, and a cash payment with respect to
the full satisfaction of the Interest Amount.

THIS DEBT SETTLEMENT AGREEMENT made as of the ______ day of ________, 2005.


AMONG:

          BARADERO RESOURCES LIMITED., a company having an office at 1305 - 1090
          West Georgia Street, Vancouver, BC V6E 3V7

          ("Baradero")

AND:

l         MAGELLAN  GOLD  CORP.  (TO BE RENAMED  "CENTRASIA  MINING  CORP."),  a
          company  having  an  office  at  300  -  1055  West  Hastings  Street,
          Vancouver, British Columbia, V6E 2E9

          ("Centrasia")

AND:      INSERT NAME AND ADDRESS (Address is confidential)

          (the "Creditor")

WHEREAS:

A.        Centrasia  is indebted to the  Creditor in the amount (the  "Principal
Amount") plus accrued  interest (the  "Interest  Amount") as set out in Schedule
"A"  attached  hereto.   The  Principal  Amount  and  the  Interest  Amount  are
collectively, the "Debt".

B.        Baradero, Centrasia and all of the shareholders of Centrasia intend to
enter into a share purchase agreement,  pursuant to which Baradero will agree to
purchase all of the issued and outstanding  shares (the  "Centrasia  Shares") of
Centrasia in  consideration  for common  shares of Baradero,  such  agreement as
amended  from time to time  being  herein  referred  to as the  "Share  Purchase
Agreement".  The common  shares of  Baradero  are listed for  trading on the TSX
Venture Exchange (the "Exchange"), and the purchase of the Centrasia Shares will
constitute a reverse take-over (the "RTO") under the policies of the Exchange.

C.        It is a condition  precedent of the Share Purchase  Agreement that, on
or before the closing (the "Effective  Date") of the RTO, Baradero will purchase
the Debt from the Creditor in  consideration  for the repayment of the Principal
Amount in Units of Baradero  (as defined  below) and the payment of the Interest
Amount in cash, in the amounts as set out in Schedule "A" attached hereto.

D.        Each Unit will be issued at a deemed  price of Cdn$0.20 and consist of
one common  share in the capital of Baradero  (a "Share")  and one common  share
purchase warrant of Baradero (a "Warrant").  One Warrant will entitle the holder
to purchase one additional common share (a "Warrant Share") at an exercise price
of $0.40 per Warrant Share for a period of two years from the date of issuance.

E.        Baradero's  obligation to complete the  transactions  contemplated  by
this Agreement will be subject to the concurrent completion of the RTO.

                                       2



F.        The  Creditor is prepared to accept the  issuance of the Units in full
satisfaction  of the  Principal  Amount,  and a cash payment with respect to the
full satisfaction of the Interest Amount.

NOW THEREFORE  THIS  AGREEMENT  WITNESSES  that in  consideration  of the mutual
premises contained herein and other good and valuable consideration (the receipt
and  sufficiency  whereof is hereby  acknowledged)  the parties  hereto agree as

         derived therefrom, to Baradero.
3.       On the Effective Date,  Baradero agrees to purchase the Debt and all of
         the Creditor's estate,  right, title and interest in and to the Debt in
         consideration  for the  issuance  of Units in payment of the  Principal
         Amount and payment in cash with  respect to the payment of the Interest
         Amount, in the amounts as set out in Schedule "A" attached hereto.
4.       On the Effective  Date,  Centrasia  hereby  agrees to assume,  observe,
         perform,  discharge  and satisfy all  duties,  obligations,  covenants,
         terms,  conditions  and  liabilities  with  respect  to the  Debt to be
         observed,  performed,  discharged  and  satisfied  by  Centrasia  as if
         Baradero  had been the  original  lender  in the place and stead of the
         Creditor.

REPAYMENT OF DEBT

5.       Upon the Effective  Date,  Baradero will allot and issue the Shares and
         issue  the  Warrants  to the  Creditor,  in the  amounts  as set out in
         Schedule  "A"  attached  hereto,  in  full  and  final  settlement  and
         satisfaction of the Principal Amount.
6.       Upon  issuance,  the  Shares and the  Warrant  Shares,  when  issued in
         accordance  with the  terms  of the  Warrants,  will be fully  paid and
         non-assessable shares in the capital of Baradero.
7.       On the Effective  Date,  Baradero will pay to the Creditor all interest
         accrued to the Effective  Date pursuant to the terms of this  Agreement
         as set out in Schedule "A" in cash or by cheque or money order.
8.       On delivery by Baradero to the  Creditor of  certificates  representing
         the Shares  and the  Warrants  in  respect of payment of the  Principal
         Amount,  and payment in cash of the Interest  Amount in accordance with
         the provisions of this Agreement,  the Debt due to the Creditor will be
         fully  satisfied  and  extinguished  and the Creditor  will release and
         forever discharge Centrasia and Baradero and its respective  directors,
         officers and  employees  from any and all  obligations  relating to the
         Debt.

<PAGE>
                                       4



                  made as a result of any oral or written  representation  as to
                  fact or  otherwise  made by or on  behalf of  Baradero  or any
                  other person and is based  entirely upon  currently  available
                  public information concerning Baradero.


10.      The  Creditor  understands  and  acknowledges  that  it is  making  the
         representations,  warranties and agreements  contained  herein with the
         intent  that they may be relied upon by  Baradero  in  determining  its
         eligibility  hereunder  to  acquire  the  Units,  and  agree  that such
         representations  and warranties are true, accurate and correct and will
         survive the execution and delivery of this  Agreement and the Effective
         Date.

CONDITIONS PRECEDENT

11.      Each of the parties obligations under this Agreement including, without
         limitation,  its obligation to close this Agreement, are subject to the
         concurrent  closing  of the  transactions  contemplated  by  the  Share
         Purchase   Agreement  and  the  execution  of  other  debt   settlement
         agreements among Baradero, Centrasia and each of the other creditors of
         Centrasia.

CLOSING

12.      The completion of the  transactions  contemplated  under this Agreement
         shall be closed at the offices of Axium Law Group,  3350-1055  Dunsmuir
         Street,  Vancouver,  British  Columbia  at  10:00  a.m.  local  time in
         Vancouver,  British  Columbia  (the "Time of Closing") on the Effective
         Date, or on such other date as the parties may agree upon.

13.      At the Time of Closing on the Effective Date,  Baradero will deliver to
         the Creditor:

         (a)      certificates that represent the Shares and Warrants as set out
                  in Schedule "A"; and

         (b)      a cheque in payment of the Interest Amount.


RESTRICTIONS ON TRANSFERS

14.      The Creditor  agrees to only offer to sell, sell or transfer the Shares
         and Warrant Shares in accordance with the terms of this Agreement,  the
         rules of the  Exchange and in  accordance  with  applicable  securities
         laws.

15.      The Creditor acknowledges and agrees that the Shares,  Warrants and any
         Warrant  Shares issued upon  exercise of the Warrants,  as the case may
         be,  will be subject to such  trade  restrictions  as may be imposed by
         operation of  applicable  securities  legislation  and the rules of the
         Exchange and that  Baradero may be required to legend the  certificates
         representing such securities with those restrictions. This will prevent
         the Creditor from  reselling  these  securities  except in very limited
         circumstances.

16.      The  Creditor  acknowledges  and agrees that some or all of the Shares,
         Warrants  and  Warrant  Shares may be  subject  to escrow  restrictions
         imposed  by the  Exchange  (the  "Escrow  Requirement").  The  Creditor
         acknowledges and agrees that the Creditor will abide by whatever Escrow
         Requirement  is imposed by Exchange  and that the  Creditor  will enter
         into and execute the form of escrow agreement required by the Exchange.

<PAGE>



THIS DEBT SETTLEMENT AGREEMENT made as of the 30th day of March, 2005.


AMONG:

         BARADERO RESOURCES LIMITED.,  a company having an office at 1305 - 1090
         West Georgia Street, Vancouver, BC V6E 3V7

         ("Baradero")

AND:

         MAGELLAN GOLD CORP. (TO BE RENAMED "CENTRASIA MINING CORP."), a company
         having an office at 300 - 1055 West Hastings Street, Vancouver, British
         Columbia, V6E 2E9

         ("Centrasia")

AND:

         INSERT NAME AND ADDRESS [Address is confidential information]

         (the "Creditor")

WHEREAS:

A.       Pursuant to a confidential  private  placement  subscription  agreement
(the  "Subscription  Agreement")  between Centrasia and the Creditor dated on or
around  November 9, 2004 the Creditor  subscribed for shares of preferred  stock
(the "Shares") of Centrasia.  The Creditor advanced the subscription proceeds to
Centrasia as an interest bearing loan pending a change in Centrasia's authorized
share capital  structure to allow the issuance of the Shares.  Centrasia did not
issue the Shares to the Creditor.

B.       Centrasia  is  indebted to the  Creditor in the amount (the  "Principal
Amount") plus accrued  interest (the  "Interest  Amount") as set out in Schedule
"A"  attached  hereto.   The  Principal  Amount  and  the  Interest  Amount  are
collectively, the "Debt".

C.       Baradero,  Centrasia and all of the shareholders of Centrasia intend to
enter into a share purchase agreement,  pursuant to which Baradero will agree to
purchase all of the issued and outstanding  shares (the  "Centrasia  Shares") of
Centrasia in  consideration  for common  shares of Baradero,  such  agreement as
amended  from time to time  being  herein  referred  to as the  "Share  Purchase
Agreement".  The common  shares of  Baradero  are listed for  trading on the TSX
Venture Exchange (the "Exchange"), and the purchase of the Centrasia Shares will
constitute a reverse take-over (the "RTO") under the policies of the Exchange.

D.       It is a condition precedent of the Share Purchase Agreement that, on or
before the closing (the "Effective Date") of the RTO, Baradero will purchase the
Debt from the  Creditor in  consideration  for the  repayment  of the  Principal
Amount in Units of Baradero  (as defined  below) and the payment of the Interest
Amount in cash, in the amounts as set out in Schedule "A" attached hereto.

E.       Each Unit will be issued at a deemed  price of Cdn$0.20  and consist of
one common  share in the capital of Baradero  (a "Share")  and one common  share
purchase warrant of Baradero (a "Warrant").  One Warrant will entitle the holder
to purchase one additional common share (a "Warrant Share") at an exercise price
of $0.40 per Warrant Share for a period of two years from the date of issuance.

                                       2


F.       Baradero's obligation to complete the transactions contemplated by this
Agreement  will be  subject  to the  concurrent  completion  of the RTO.

G.       The  Creditor is  prepared to accept the  issuance of the Units in full
satisfaction  of the  Principal  Amount,  and a cash payment with respect to the
full satisfaction of the Interest Amount.

NOW THEREFORE  THIS  AGREEMENT  WITNESSES  that in  consideration  of the mutual
premises contained herein and other good and valuable consideration (the receipt
and  sufficiency  whereof is hereby  acknowledged)  the parties  hereto agree as
follows:

ACKNOWLEDGEMENT OF DEBT

1.       Centrasia  acknowledges  and agrees that it is indebted to the Creditor
         in the amount of the Debt.

PURCHASE OF DEBT

2.       On the Effective Date, the Creditor will sell,  assign and transfer all
         of its estate, right, title and interest in and to the Debt, as set out
         in Schedule "A" attached hereto and in the Subscription Agreement,  and
         all benefit and advantage to be derived therefrom, to Baradero.

3.       On the Effective Date,  Baradero agrees to purchase the Debt and all of
         the Creditor's estate,  right, title and interest in and to the Debt in
         consideration  for the  issuance  of Units in payment of the  Principal
         Amount and payment in cash with  respect to the payment of the Interest
         Amount, in the amounts as set out in Schedule "A" attached hereto.

4.       On the Effective  Date,  Centrasia  hereby  agrees to assume,  observe,
         perform,  discharge  and satisfy all  duties,  obligations,  covenants,
         terms,   conditions  and  liabilities  contained  in  the  Subscription
         Agreement  to be  observed,  performed,  discharged  and  satisfied  by
         Centrasia  as if Baradero  had been  originally  named as the  Creditor
         thereto in the place and stead of the Creditor.

REPAYMENT OF DEBT

5.       Upon the Effective  Date,  Baradero will allot and issue the Shares and
         issue  the  Warrants  to the  Creditor,  in the  amounts  as set out in
         Schedule  "A"  attached  hereto,  in  full  and  final  settlement  and
         satisfaction of the Principal Amount.

6.       Upon  issuance,  the  Shares and the  Warrant  Shares,  when  issued in
         accordance  with the  terms  of the  Warrants,  will be fully  paid and
         non-assessable shares in the capital of Baradero.

7.       On the Effective  Date,  Baradero will pay to the Creditor all interest
         accrued to the Effective  Date pursuant to the terms of this  Agreement
         as set out in Schedule "A" in cash or by cheque or money order.

8.       On delivery by Baradero to the  Creditor of  certificates  representing
         the Shares  and the  Warrants  in  respect of payment of the  Principal
         Amount,  and payment in cash of the Interest  Amount in accordance with
         the provisions of this Agreement,  the Debt due to the Creditor will be
         fully  satisfied  and  extinguished  and the Creditor  will release and
         forever discharge Centrasia and Baradero and its respective  directors,
         officers and  employees  from any and all  obligations  relating to the
         Debt.

                  of any material  information  concerning Baradero that has not
                  been publicly disclosed and the Creditor's decision to acquire
                  the Units has not been made as a result of any oral or written
                  representation as to fact or otherwise made by or on behalf of
                  Baradero  or any  other  person  and is  based  entirely  upon
                  currently available public information concerning Baradero.

10.      The  Creditor  understands  and  acknowledges  that  it is  making  the
         representations,  warranties and agreements  contained  herein with the
         intent  that they may be relied upon by  Baradero  in  determining  its
         eligibility  hereunder  to  acquire  the  Units,  and  agree  that such
         representations  and warranties are true, accurate and correct and will
         survive the execution and delivery of this  Agreement and the Effective
         Date.

CONDITIONS PRECEDENT

11.      Each of the parties obligations under this Agreement including, without
         limitation,  its obligation to close this Agreement, are subject to the
         concurrent  closing  of the  transactions  contemplated  by  the  Share
         Purchase   Agreement  and  the  execution  of  other  debt   settlement
         agreements among Baradero, Centrasia and each of the other creditors of
         Centrasia.

CLOSING

12.      The completion of the  transactions  contemplated  under this Agreement
         shall be closed at the offices of Axium Law Group,  3350-1055  Dunsmuir
         Street,  Vancouver,  British  Columbia  at  10:00  a.m.  local  time in
         Vancouver,  British  Columbia  (the "Time of Closing") on the Effective
         Date, or on such other date as the parties may agree upon.
13.      At the Time of Closing on the Effective Date,  Baradero will deliver to
         the Creditor:

         (a)      certificates that represent the Shares and Warrants as set out
                  in Schedule "A"; and

         (b)      a cheque in payment of the Interest Amount.


RESTRICTIONS ON TRANSFERS

14.      The Creditor  agrees to only offer to sell, sell or transfer the Shares
         and Warrant Shares in accordance with the terms of this Agreement,  the
         rules of the  Exchange and in  accordance  with  applicable  securities
         laws.

15.      The Creditor acknowledges and agrees that the Shares,  Warrants and any
         Warrant  Shares issued upon  exercise of the Warrants,  as the case may
         be,  will be subject to such  trade  restrictions  as may be imposed by
         operation of  applicable  securities  legislation  and the rules of the
         Exchange and that  Baradero may be required to legend the  certificates
         representing such securities with those restrictions. This will prevent
         the Creditor from  reselling  these  securities  except in very limited
         circumstances.

16.      The  Creditor  acknowledges  and agrees that some or all of the Shares,
         Warrants  and  Warrant  Shares may be  subject  to escrow  restrictions
         imposed  by the  Exchange  (the  "Escrow  Requirement").  The  Creditor
         acknowledges and agrees that the Creditor will abide by whatever Escrow
         Requirement  is imposed by Exchange  and that the  Creditor  will enter
         into and execute the form of escrow agreement required by the Exchange.
