4. STRATEGIC RATIONALE
Creates a new zinc company that has:
• Immediate Production and Robust Growth
• Expected production from two operating mines in 2011 – 2012
• Cash flow anticipated in mid-2011 once Halfmile begins supplying ore on a toll
milling basis to Xstrata Zinc’s Brunswick 12 Mill (“BMS”) and Santander begins
commissioning its mill in late-2011
• Robust project pipeline in the short and medium term, including a potential mill
expansion at Santander, and construction of a new mill at Halfmile-Stratmat after
BMS closes
• Resource and Production Growth, Re-rating Opportunity
• Strong re-rating potential via a portfolio of mines, near-term cash flow, increase in
resources and a strong production growth profile
• High potential to increase the current pro-forma NI 43-101 resources of 4.5 billion
lbs zinc, 1.1 billion lbs lead, 31.4 million ounces silver and 625 million lbs copper1
• Operations diversified across two world-leading mining jurisdictions
• Diversified Commodity Mix – Zinc, Silver, Lead, Copper, Gold
• Company is well positioned for the current strong commodity price environment,
and the anticipated near-term zinc commodity price increase
• Proven Management Team and Strong Partners
• World leading partners – Glencore International and Xstrata Zinc
• Experienced management team and board of directors

5. VALUE FOR KRIA SHAREHOLDERS
• Attractive premium of 33.6% over the Kria closing price on December 15, 2010
• Attractive premium of 25.2% based on the 30-day VWAPs of both companies for the
period ended December 15, 2010
• Will own approximately 25.8% of the outstanding shares of the combined company
on a basic basis and approximately 26.9% assuming options and warrants in the
money, on a fully-diluted basis
• Cardero, an insider of both Kria and Trevali, provides an US$8.0 million loan to Kria,
in order to pay the January 2011 Halfmile Lake and Stratmat Property Payment due
to Xstrata Zinc
• Trevali’s balance sheet and its cooperation with Cardero, greatly improve Kria’s
financing alternatives and balance sheet
• Kria’s shareholders gain access to Trevali’s Santander development project, with
restart capital costs estimated at approximately US$19 million (US$12 million
financed by Glencore, the operator and Trevali’s partner)
• Considerable upside potential exists in growing the Santander resource
• Participation in Trevali’s potential growth through further acquisitions
5

6. SECURED DEBENTURE
• Cardero will issue to Kria a secured term loan
• Amount of US$8.0 million
• Proceeds to be used to pay the January 2011 Halfmile Lake and Stratmat Property
Payment due to Xstrata Zinc
• One year term loan, payable in full, plus interest, one year after advance (repayable
on or before January 14, 2012)
• Coupon of 10.0% per annum, calculated monthly, not in advance
• Subject to the approval of shareholders of Kria, other than Cardero, the loan terms
will be retroactively modified to bear interest at 8.0% per annum, and Kria will issue
to Cardero approximately 6.4 million warrants, exercisable into common shares of
Kria for a period of one year after the date of issuance of the warrants at a price of
C$0.25/share
• Security is a first charge, mortgage and security interest over all of the assets and
undertaking of Kria
• Subject to completion of satisfactory corporate, technical and legal due diligence by
Cardero on Kria and its assets

7. ABOUT TREVALI RESOURCES CORP.
• 2,000 tpd Zinc-Silver-Lead production targeted for 2011 from the Santander Project located 215 km
by road from Lima in Peru’s Central Mineral Belt
• Strategic partnership with Glencore International AG providing 2000 tpd plant, contract mining and
manpower in exchange for LOM concentrate offtake agreement – mitigates both financial and
technical risks
• Trevali retains full 100% ownership in Santander project and can acquire ownership of Glencore’s
processing plant via toll charge
• CAPEX – modest due to existing infrastructure and Glencore providing 2,000 tpd processing plant
and contract mining fleet
• OPEX expected to be lower quartile – significant silver/lead credits
• Very significant exploration potential to expand silver-lead-zinc resource. Exploration in 2009 –
2010 resulted in indicated tonnage increasing 53%, inferred up 452%
• Tingo hydroelectric power generating facility – low cost, renewable power supply – surplus capacity
can provide significant future revenue stream or sufficient power for a 4,000 tpd operation

• Planning to fast-track development of Halfmile Lake deposit by beginning to custom mill
at Xstrata’s Brunswick 12 mill in mid 2011
• Excellent leverage to rising metal prices

prices of US$1.03/lb Zn, US$3.03/lb Cu, US$0.92/lb Pb and US$15.08/oz Ag
• IRR and NPV increased 28% and 82% respectively over the previous Halfmile PEA
completed in July 2009
Phase I Production – Phase 2 Production –
2011-2012 2012 and beyond
Develop Halfmile Build mill and operate Halfmile/Stratmat
 Provide feed to Xstrata’s Brunswick 12 mill in  Complete feasibility

12. SANTANDER PROJECT
• 44-sq. km property in the world-class Central Peruvian Polymetallic Belt
• 215 km from Lima by road – government upgrading all access routes
• Multiple exploration targets, including all deposits open at depth
• Fully supported 200-man camp currently being expanded to support mine construction and operation
• Coarse grained mineralogy provides good recoveries to produce clean concentrates
• 90% Lead recovery at 50% concentrate grade with 40-50 oz/t silver
• 85% Zinc recovery at 50-52% concentrate grade
• 80-85% Silver recovery (to lead concentrates)
• Production starts at 2,000 tpd and is to be expanded to 4,000 tpd, with a 20+ year mine life
• Local communities on board, and highly supportive
• All required surface land rights obtained, tailings permitted, water rights permitted and the mine plan
submitted – permit pending
• Detailed processing plant engineering underway – basis for final plant permit
• Glencore has commenced construction with plant commissioning scheduled for approximately Q4 –
2011
• Glencore is financing the US$12M plant construction, and will be repaid US$5.95/tonne milled
• Trevali has secured a long-term concentrate off-take sales agreement whereby Glencore will buy 100%
of the Santander project area life-of-mine production at benchmark terms
12

13. TINGO POWER GENERATING STATION
• The Tingo run-of-river hydroelectric generating station is situated 17 km west, down-valley,
from the Santander mine site and has operated since 1958 generating up to 1.6 MW of
electricity – partly servicing the power needs at the Santander mine
• Advanced discussions are underway with several banks for debt financing to increase
generating capacity from current 1.6 MW to approximately 8.8 MW (10 MW peak), upgrade
the existing transmission line, and extend the line to connect to the Peruvian National Energy
Grid allowing for sale of excess power and cash flow to Trevali
• Expansion capital expected to be of US$20-22M (~US$15M expected through debt financing)
