NOTE: Assuming US $1,415/oz Au and US $27/oz Ag Chesapeake Gold Corp. has completed an independent Preliminary Feasibility Study on its 100%-owned Metates goldsilver-zinc project located in Durango State, Mexico. The study updates a 2011 Preliminary Economic Assessment. Proven and probable reserves are pegged at 18.5 million ounces of gold, 526 million oz of silver and 4.2 billion pounds of zinc. The life-of-mine average annual production would be 659,000 oz gold, 15.9 million oz silver (954,000 oz gold equivalent) and 143 million pounds zinc. The average annual pre-tax cumulative net operating income is $7,731,313,000 in operating years two through seven for a cumulative life-of-mine pre-tax net operating income of $20,290,557,000. The project is envisaged as a conventional, truck and shovel, open pit, mining operation estimated to have a 25-year mine life. Crushed ore would be fed to a conventional SAG and ball mill circuit followed by a single stage flotation plant to produce a bulk sulfide concentrate. Initial production would start at 60,000 tonnes per day during year one with additional capital being spent to increase production to 120,000 tpd in year two. Water conservation practices used at both the Metates and Ranchito locations will enable the project to be generally self-sufficient using site surface water storage and locally sourced groundwater. After the pit has been mined, tailings from the processed low-grade stockpile will be backfilled and contribute to a sustainable, long-term pit lake. Chesapeake Gold is sufficiently financed to advance the Metates Project towards completion of a full feasibility study. JUNE 2013 Sulliden Gold Corporation Ltd. is focused on bringing to production its 100%-owned Shahuindo gold-silver project located in Peru. Since 2009, the company has delivered two resource updates, completed a PEA and Feasibility Study, and is now in the final stages of permitting. NI 43-101 compliant measured and indicated oxide gold resources total 2,438,000 oz with inferred gold resources at 1,628,000 oz. Company geologists believe there is excellent potential to expand resources as several prospective targets have yet to be drilled and the property remains largely unexplored. Based on a September 2012 Feasibility Study (includes only 40% of resources), the operation would be a shallow, openpit, heap leach mine. This initial 10,000 tpd scenario would produce approximately 90,000 oz of gold equivalent annually, and is easily scalable to accommodate all the defined resources and future mineral growth. Shahuindo stands out for its low CAPEX ($131.8M), low cash costs ($552/ oz; $826/oz all-in costs) and attractive IRR (Pre-tax: 52.2%; Post-tax: 37.8%). The life-of-mine strip ratio (waste:ore) would be 1.91:1 over 10.4 years. In April 2013, Sulliden received approval for its Environmental Impact Study (EIS) and obtained a construction permit from the Peruvian Ministry of Energy and Mines for a switchyard and electrical facilities, where it will draw power for the mine. The company expects to receive EIS approval and obtain a construction permit for its mine before the end of 2013. In April 2013, Agnico-Eagle Mines Ltd. [AEM-TSX; NYSE] signed a subscription agreement to make an investment of $24 M into Sulliden through a non-brokered private placement.  GOLD CANYON RESOURCES INC. [GCU-TSXV; GDCRF-PK] NPV (5% Discount)....................$579 million IRR (Pre-Tax)...................................... 25.4% Payback Period...............................1.7 years Cash Costs (Au Eq/oz)......................$636/oz Capital Costs.............................$438 million Shares Outstanding.................. 135,625,018 NOTE: Assuming US $1,300/oz Au. Gold Canyon Resources Inc. has received a Preliminary Economic Assessment from SRK Consulting (Canada) Inc. for its 100%-controlled Springpole gold project located 110 km northeast of Red Lake, northwest Ontario. The PEA is based on the project's most recent NI 43-101 compliant mineral resource estimate that includes an indicated resource of 128.2 million tonnes grading 1.07 grams gold/tonne and 5.7 grams silver/tonne and an inferred resource of 25.7 million tonnes grading 0.83 grams gold/tonne and 3.2 grams silver/tonne at a cutoff grade of 0.4 grams gold/tonne. A net smelter return royalty (NSR) of 3% has been applied in the PEA; although, various royalty agreements allow for the royalty to be incrementally bought-down. The project is envisaged as an open pit mining operation with the construction phase of the project scheduled for two years. Dike construction and dewatering costs are estimated at US $53 million and include cofferdam construction, dewatering, dredging of sediments, and fish compensation measures. The PEA assumes mining an average 50,000 tonnes of material (mineralized and waste) per day from the open-pit. Mine life would be 11 years, during which time 72.4 million tonnes of mineralized material will be delivered to the mill and 120.8 million tonnes of waste rock will be deposited in the waste disposal facility. The strip ratio (waste: ore) is 1.7:1. During full production, estimated annual production would be 217,000 oz of gold and 1,200,000 oz of silver. A Pre-Feasibility Study is planned. As of February 2013, Gold canyon had over $10 million in cash. www.resourceworld.com 9
