In 2008, Copper Mountain succeed in finishing one of the largest drill programs in Canada (106,000 meters) and increased the resource estimate by 45% to 5 Billion pounds of copper. The goal of the program was achieved when the results confirmed continuity of mineralization between the pits.
The Current mine plan merely scratches the surface of the visible anomalies that extend to depth. Copper Mountain will continue to test these deep anomalies and sees “blue sky” potential to develop a world class deposit upon successful proof of mineralization below the planned super pit outline.

Press release- Northgate Minerals
“With the validation of the Titan system as an exploration tool for the terrain and deposit types in the Kemess camp, additional surveys have been contracted to more completely map out the area around hole KH-07-04, as well as to explore other areas of the Kemess North system and areas adjacent to the Kemess South pit. In addition to this survey work, Northgate will be drilling additional holes in and around the Altus and Ora zones during the 2007 exploration season. Total exploration expenditures on the Kemess property in 2007 are now expected to reach $4 million.”
Ken Stowe, President and CEO Imperial Metals, BC Red Chris: Cu-Au Red Chris- Exploration Objectives
o To define the depth and strike length potential of the Cu-Au mineralization prior to full mine development and to guide additional deep drilling. o To define the quartz stockwork system containing the mineralization to depth and to determine if the system is connected solely to the Red stock monzonite. o To assist in the targeting of deep exploration holes.

“A new, high-grade copper discovery, called the ‘Lower Breccia Zone’, lies below the known mineralization at the North Zone and was intersected during the 2011 drill campaign. It is spatially coincident with a large and conductive geophysical anomaly previously identified by the Titan 24 geophysical surveys.” Romios, Pess Released 20120305 (TrekStatusASM) Romios Gold Resources Inc. Newmont, Nevada Copper Basin: Cu-Au-Mo Copper Basin- Nevada
Newmont’s Buckingham stockwork molybdenum deposit is located in the Copper Basin area of Nevada. It comprises a Late Cretaceaous calc- alkaline porphyry system estimated to contain more than 1,000 million tons of mineralized rock averaging 0.10 weight percent Mo and small amounts of Ag, W, Cu and Au. Copper Basin- Nevada
A Titan 24 survey was conducted across an area of historic Cu and Cu-Au open pit mining in the Copper Basin area of Central Nevada.
The aim of the survey was to map chargeability anomalies associated with potential secondary supergene chalcocite copper mineralization and copper Skarn hypogene mineralization. The survey traverses an area between historic open pits. TITAN 24 DCIP & MT Survey Profile

o Titan 24 successfully identified at least five geophysical anomalies in the DCIP results from near surface to approximately 500 m depth. Three anomalies were classified as high priority targets. o A deep conductor more than 300m deep was identified as a high priority target (potential extension of known mineralization.) o Resistivity lows extend to least 500m depth over much of the surveyed area, further supporting the potential to extend significant gold mineralization to depths beyond those drilled to date. o The deposit comprises a current NI 43-101 compliant resource of 2.7 Mt at 5.85 g/t gold for 508,000 oz gold (indicated) and 1.27 Mt at 5.98 g/t gold for 244,000oz gold (inferred). St. Elias Mines/ Kernow Resources JV, Portugal Gralheira/Jales: Gold Grahleira/Jales Property
The Gralheira/Jales Gold Property covers approximately 1,250 acres (500 hectares) and is located in northern Portugal. The
The Gralheira gold and silver deposit lies 700 metres north of the Jales mine and is contained within an extensive mineralized shear zone that extends for 3,000 metres.
The main gold mineralization is hosted within a system of sub-parallel veins ranging from 0.5 m to 1.5 m in width.
Jales was mined to a depth of approximately 620 m and is known to be a mesothermal system, as is Gralheira. Exploration Objectives
To prove that the vein system continues to depth.
To strengthen the geologic understanding outside of previously drilled areas, and to reduce overall drilling costs by eliminating unprospective ground from exploration drilling.
To enhance exploration efforts in the vicinity of the mine, providing drill targets related to satellite ore bodies. A) L100W – SHARP 2D IP CHARGEABILITY

TITAN surveys have identified over 15 major chargeability high and resistivity low anomalies, that are consistent with vein-gold mineralized zones, and lie buried from 100-750m depth.
Anomalies are oriented along 5 linear trends (A-E) that extend across the property.
Zone A corresponds to the main Gralheira vein system. It is mapped from surface to >500-750m depths as an IP high feature. Additional secondary veins are indicated north of main Gralheira system.
Zone B is a secondary system that subcrops and lies south of Gralheira. Zone D is a buried system north of Gralheira. Zones E and C are deeper features with weaker IP signatures.
Twenty-five anomalies are drill-targeted, including 8 first priority features that offer sufficient strength and depth-extent. Follow-Up Drill Results
Prior to this drill program, the majority of holes previously drilled along the 2,000 m strike length of Gralheira tested for mineralization only between the surface and a depth of 200 m.
The single deepest previous intercept was 300 m below surface
The drill program consisted of 11 drill holes, some intersecting high grade gold and silver mineralization. The drill program successfully intersected mineralization up to 511 m below surface, with most drill holes intersecting mineralization between 380 m and 480 m below surface.

The Phoenix Deposit, discovered in 2007 by a TITAN 24 survey, is an unconformity- type uranium deposit on the southeastern margin of the Athabasca Basin, located approximately midway between the McArthur River mines and the Key Lake mill.
The Phoenix deposit has been identified along a strike of 900+ m, associated with a graphitic shear zone adjoining a basement quartzite ridge Exploration Objectives
o To use TITAN 24 DC/IP to help delineate structures containing unconformity Uranium mineralization for efficient drill planning. o To construct a complete geophysical map of the property to better understand basement structure.
Previous Exploration A TITAN 24 survey conducted in 2007 clearly identified the alteration zone associated with Phoenix as a conductive zone protruding through the unconformity. Several follow-up surveys conducted in subsequent years provided a detailed and comprehensive map of basement structures, and mapped the Phoenix zone along strike. Drilling has mapped a high-grade zone over a strike of 250+ m, and the deposit remains open in all directions. DC Resistivity Plan Map, 450 m Depth Titan 24 Survey Results
The structure hosting the Phoenix deposit is well defined as a conductive lineament in the basement. Several other conductive lineaments in the basement provide secondary exploration targets.

Rapid exploration Trevali Mining Corp., New Brunswick Halfmile Mine: VMS Halfmile Mine- New Brunswick
Conventional geophysics had failed to detect and map to depth the largest of the three massive sulfide lenses found at the Half Mine base metal VMS deposit in New Brunswick. The deepest and largest sulfide lens was left undiscovered for decades. As a result, the full value of the deposit was not known. Halfmile Mine- New Brunswick
The Halfmile Mine is located in northern New Brunswick, Canada, approximately 60 kilometres southwest of Bathurst and 40 kilometres from the Brunswick 12 Mine in the Bathurst Mining Camp. The property consists of 73 claims and covers an area of 1,104 hectares.
The property was heavily explored by Xstrata Zinc and its predecessor companies at intervals since the 1960s. Trevali believes that its Halfmile and Stratmat properties represent the largest and highest-grade undeveloped deposits in the Bathurst Mining Camp.
Geology The Halfmile Property contains 4 sulphide zones: Upper, Lower, Deep and North. The deposit is a volcanic-sediment-hosted massive sulphide deposit and is one of over 45 massive sulphide deposits in the Bathurst Mining Camp. Rocks are of Ordovician age and have undergone a complex history of polyphase folding and faulting. The deposit is structurally overlain by rhyolitic and dacitic rocks as well as disconformable quartz-wackes and pelites. Half Mile Mine- TITAN 24 Results
TITAN 24 detected and mapped the vertical extent of the Half Mile base metal VMS deposits in New Brunswick, to a depth of over 1500 m. As a result Titan 24 was able to map the largest and deepest massive sulfide lens that was discovered several decades after the initial discovery of the near surface zone.

Kimberlite pipe discovered in 1972.
Comprises three steep-sided pipes that connect to each other approximately 100m below the present day surface. The pipes are referred to as the South, Centre and North lobes.
Jwaneng pipes are dominated by two types of kimberlite – a volcaniclastic kimberlite and a dark pyroclastic kimberlite.
Titan 24 survey objective was to image lobes to depth for reliable mapping of deposit size and geometry. Exploration Objectives
To determine the geo-metric characteristics of the pipe well below the limitation of current physical information from mining and drilling.
Improve mine planning and provide future cash flow implications by better estimating future mining potential.
Exploration Challenge:
Operating within the active mine environment while collecting accurate and useful information in an extremely culturally effected area. Jwaneng- Survey Results
Titan mapped geometry of kimberlite pipe to 800m.
Resistivity contrasts within the kimberlite, associated with different diamond bearing facies were mapped with the Titan 24 data. These results impact delineation drilling, mine planning and discovery processes.
