MAX believes that Majuba Hill is a newly-defined silver/copper/gold porphyry system that is highly prospective for a bulk-tonnage, open pit deposit. Since acquiring an interest in the property in March 2011, MAX has conducted extensive exploration programs which included soil sampling, data compilation and mapping and core drilling. During a Phase I core drilling program completed in August 2011, MAX encountered long intervals of high-grade silver and copper near surface in five of eight holes, as well as significant gold intercepts. Highlights of this drilling include:

Majuba Hill is the site of numerous past producing mines, with historic production reported of 12% Cu (Mason Valley Copper, 1918) and silver grades up to 40 oz/t Ag. Majuba Hill encompasses 2,568 acres of surface and mineral rights that includes patented lode mining claims and is located approximately halfway between the Florida Canyon Mine (Jipangju) and the Hycroft Mine (Allied Nevada Corporation). The property is easily accessed via 23 miles of well-maintained dirt roads leading from U.S. Interstate 80, and lies 30 miles northwest of Coeur d'Alene's Rochester silver mine, which contains a NI 43-101 compliant Measured and Indicated Resource of 263.9 million tons grading 0.46 oz/ton Ag and 0.004 oz/ton Au. (The Coeur Technical Report on the Rochester Mine is available on SEDAR).
On December 3, 2012, MAX entered into a Mining Lease and Option to Purchase Agreement with Claremont Nevada Mines LLC of Nevada and JR Exploration LLC of Utah whereby MAX can acquire a 100% interest in the Majuba Hill Silver/Copper/Gold property by paying US$1 Million over a four year period, with $200,000 having been paid on signing and $200,000 payable each year on the anniversary of the effective date. This new Lease Agreement replaces the previous Option Agreement with Claremont dated March 4, 2011; under the terms of this new Lease Agreement, there will be no annual work commitments and the NSR will be reduced from 3% to 1%.

2011 EXPLORATION PROGRAMS
In September 2011 MAX received and mapped the results of an extensive soil sampling program at Majuba Hill. A total of 834 soil samples were taken across a surface area in excess of 5,000 by 2,500 meters (m) with assay results obtained as high as 1.53% Cu and 209 g/t Ag.
On the northwest side of the Majuba Hill property, on unpatented land, assay results in soils ranged from 1.8 ppm Cu to 15,300 ppm (1.53%) Cu and from nil to 209 g/t Ag. Sampling undertaken on the newly identified "Ball Park" target area 1 km east of the Copper Stope target area (the site of MAX's Phase I drill program) returned values from 61.2 ppm to 132 ppm Cu and from 0.16 ppm to 2.5 g/t silver. Both of these areas are identified on the soil geochemistry maps below, with the target areas outlined in black. MAX plans to drill both of these areas during a Phase II drill program that began in October 2011.
In addition, MAX has acquired historic reports prepared by the United States Bureau of Mines (USBM Report of Investigations #4378, 1948) that reported assay results from drilling undertaken at the past producing Majuba Hill mine in 1943. The USBM drilled two short horizontal holes into the walls of the drifts, aimed toward the west. The first hole averaged 0.73% Cu over its entire length of 46 feet and 0.75 opt Ag over 16 feet. The second hole contained 2.0% Cu and 0.70 opt Ag over the entire 45 feet. This area, underneath the Copper Stope, will be explored during the fall drill program.

Phase I Drill Program - Summer 2011
During the summer of 2011, MAX drilled eight core holes at the site of the past producing Majuba Hill mine on patented land. Five of the eight holes were drilled to test results reported by Minterra Resource Corp. from a reverse-circulation drill program conducted in 2007. This drilling confirms higher results for both copper and silver than previously reported by Minterra due to the improved sample recovery provided by core drilling. In addition, significant gold (Au) values were encountered in all drill holes; no gold assays had previously been reported by Minterra, nor finding native gold in the holes as we have.
The complete assay results from the eight hole Phase I drill program at Majuba Hill are as follows:

Analysis was performed by Inspectorate American Corp. Laboratories, an ISO certified facility in Reno, Nevada, using fire assay and multi-element (ICP-ES) techniques producing assays for a 49 element suite of minerals. Standards, duplicates and blanks were used for quality control of the samples. After the core is logged for each drill hole, the location of each site is located using a GPS in UTM coordinates using NAD 27 datum. The core is then split and put into a sample bag which is labeled for each interval and a sample card tag put in each sample bag and taken from the core facility to the Inspectorate Laboratories.
Phase II Drill Program - Fall 2011
In October 2011 MAX commenced a Phase II core drilling program at Majuba Hill. MAX plans to drill a minimum of five holes to test new target areas identified during mapping, data compilation and soil sampling conducted over a surface area in excess of 5,500 by 2,500 m during 2011. The first drill hole of the program (MM-17) was collared on the "Ball Park" target area immediately to the east of our Phase I drill program completed this summer, where drill results included high grade intercepts such as 44.2 m of 71.0 g/t silver and 1.14% copper commencing within 5 feet of surface in hole MM-06 (see the listing of drill results in the table above). Hole MM-17 is located approximately 730 meters to the east of hole MM-06 and is the first of two holes planned to test the eastern extension of the high grade mineralized zone we've identified at Majuba Hill. Targeting of these drill holes was determined through analysis of work done by Freeport Sulphur in 1941 and progress drilling reports obtained from Minefinders, which reported significant copper and silver drill intercepts during exploration conducted in 1972 (Minefinders Progress Report No. 7). A third hole is planned to the southeast of our recent Phase 1 drilling to test the depth and extent of the known mineralized zone below and east of the past producing Majuba Hill mine and has been targeted based on our recent examination of skeletonized drill core from Minefinders drilling in 1972 that had been stored at the Nevada Bureau of Mines.

The fourth and fifth drill holes are planned to test for the extension of the mineralized zone approximately 1.4 kilometers to the northwest of hole MM-06, following up on soil assay results obtained as high as 1.53% Cu and 209 g/t Ag. Maps showing the results of this soil sampling and the drill holes planned at Majuba Hill can be viewed above.
Since 1907, production and exploration at Majuba Hill has produced outstanding copper results with associated silver and gold. Published production data show that prior to 1947 Mason Valley Mines Co. and Greenan-Kerr produced 4,000 tons @ 12 % Cu and slightly less than 23,000 tons @ 4% Cu respectively. Majuba also has the rare distinction of being one of the few tin producers (350 tons @ 2 to 4% tin) in the western United States. Historically, copper and tin were mined from underground workings at Majuba. Copper, silver, and tin ore was taken from stopes along the Majuba Fault, which cuts northwesterly across the nested series of intrusives, intrusive breccias, and dikes. Gold values are also reported from the historic record. The ore stopes and workings extended to about 500 feet below the surface and 250 feet along the fault.
The Last Chance (Frisco) mine in section 1, T32N, R31E was developed along a fault with a trend similar to the Majuba Fault. Last Chance operated intermittently and produced silver (up to 40 opt Ag), lead (up to 15%), and gold (up to 0.10 opt Au) from an 830 foot tunnel and a 117 foot deep shaft. No drilling or exploration appears to have ever been completed down dip or along the strike of the fault at the Last Chance.
Total production reported from historic underground mines in the project area (see Nevada Bureau of Mines and Geology Bulletin 86) included:
The current land position is based on the concept that Majuba Hill is the lode source for gold found as nuggets at the nearby Majuba Placers.
When the core land position (10.5 square miles established by Minterra Resource Corp.) was being assembled, public domain and private data pointed to an area adjacent to the historic, high-grade copper workings with potential for a solvent extractable (SXEW) type copper deposit.
Minterra implemented an immediate drill campaign, thus a great deal of base line geologic data was not compiled until after the drilling was initiated. Minterra subsequently reached the end of its corporate life and their exploration program ceased. All data collected and reported on by Minterra Resource Corp. between March 2006 and May 2008, including geophysical data (a 14.4 line-km IP survey), assay certificates, interpretive maps, cross sections and digital data has been made available to MAX. Exploration is currently underway and will include core drilling as early as April 2011.
Highlights of reverse-circulation drilling reported by Minterra Resource Corp. in 2007-8 included:
COPPER AND SILVER TARGETS
The primary line of evidence pointing to the copper potential at Majuba Hill is exploration data from 1975 to 1981 that was collected adjacent to the historic production from the Majuba Mine, combined with the results of drilling conducted by Minterra in 2007.
The underground sampling and descriptions of the work from Texas Gulf Chemical & Metallurgical indicated that additional high-grade copper probably occurs immediately east of the historic Copper Stope in the Majuba Mine. Texas Gulf was primarily exploring for tin to provide smelter feed for their Texas plant. While completing a shallow drilling campaign around the tin stope portion of the Majuba Mine they intersected thick intervals of chalcocite, oxide and carbonate copper. The new zones combined with the reported historic production suggest this area has potential for an SXEW-type, high-grade oxide copper deposit.
The Minterra copper and silver drill results were encouraging but were not followed up. The combination of geology, geochemistry and drill results still point to the patented lode claims around the historic Majuba Mine as a significant copper/silver target.
The Majuba Placers is a three to five square mile area known for its gold nuggets that adjoins the eastern side of the project area. Numerous weekend prospectors and "metal detectors" have found a variety of gold nuggets and crystalline gold at the Majuba Placers; Majuba is the mineral system that is the most likely lode source for these gold nuggets (see picture below).
The idea that Majuba Hill is the gold source was strongly supported by Minterra surface geochemical sample results which returned a high of 10.15 g/t gold (0.3 opt gold). Widespread detectable gold outlined by Minterra was not previously reported for the Majuba Project area and is summarized in the following table:
Gold values in the Minterra drilling further supported the idea with the following results:
Higher grade gold values returned suggest that the gold is primarily associated with:
