Carmax Mining Corp. ("Carmax") is very pleased to announce the results for the recently completed Quantec Titan-24 DCIP survey at its 100% owned Eaglehead copper-molybdenum-gold-silver project located in northwest British Columbia.
To view the 3D geophysical model of the Eaglehead deposit, go to the Carmax website at http://www.carmaxmining.com/properties/maps/. In addition to the Quantec results, Carmax is pleased to announce that the second of the six hole drilling program has been completed. Highlights are as follows:
Highlights:
- The chargeability anomaly consisting of two distinct chargeability signatures has been defined over a 5,600m long horizontal distance,
- From Line 1 to Line 8 (horizontal distance of 4,500m) a strong >20 mRad chargeability signature occurs that covers four of the six zones of mineralization identified to date. This signature is open to the northwest towards the West zone,
- The >20 mRad chargeability signature ranges from 500m to 1,000m wide, is open at depth below the -550m level and is surrounded by a >10mRad chargeability signature that changes in width along strike,
- The mineralization in the historical (where sampled) and current drill holes in the Pass, Camp, Bornite and East zones of mineralization (horizontal distance of 3,000m), either on or in proximity to the geophysical survey lines, shows a good correlation to the >20 mRad chargeability signature,
- On Line-9 and Line-10 (horizontal distance 1,100m) a distinct >10 mRad chargeability signature occurs that is approximately 1,000m wide and is open at depth below the -550m level. This chargeability signature has not been drill tested and is open to the southeast towards the mineralized zone referred to as the Far East zone, and
- The >10 mRad chargeability signature on Line-3 was tested by DDH 32 approximately 400m east of the >20 mRad chargeability contour. This historical drill hole appears to have tested the zone of oxide copper mineralization located earlier in 2014 on Line 2 and Line 3. Where sampled (3 samples) this hole returned values ranging from 0.33 to 0.67% copper.
Mr. Jevin Werbes, President of Carmax stated, "The Quantec Titan 24 survey, combined with the analytical results of the historical and current drilling, has outlined a large, positive chargeability anomaly that, based on drill hole information, appears to be mineralized over a 4,500m long portion of this anomaly. Four of the six zones of mineralization located to date on the property occur within this 4,500m long portion of the anomaly suggesting that these zones are parts of a much larger, contiguous zone of mineralization. The second chargeability anomaly located on Line 9 and Line10 is significantly different and has not been tested by drilling. Both anomalies are open along strike. The majority of the historical drill holes completed along the 4,500m strike length of the first chargeability anomaly where sampled are mineralized. A review of the available drill logs for these holes describe visible copper mineralization in those parts of the core that have not been sampled."
Quantec Titan-24 DCIP and MT Survey:
Quantec Geosciences Limited (Quantec) completed an 18 kilometers (ten lines) of DCIP survey on the Eaglehead Project in July 2014. To view the results of the Quantec survey go to the Carmax website at http://www.carmaxmining.com/properties/maps/.
The first chargeability signature that has been outlined for the Eaglehead project (including the four zones of mineralization) has been tested with over 122 historical and current diamond drill holes. The majority of these holes, based on historical assays where sampled, are reported to contain significant copper mineralization. For example, the drill holes that occur either on or close to the Quantec lines were selectively sampled (from one to four samples per drill hole) over intervals ranging from 2.1m to 54.3m in length and copper grades ranging from 0.10% copper over 6.7 m to 0.65% copper over 18.2m. A brief discussion of the chargeability anomaly (>20 mRad) outlined by the recent survey is presented below. Inclusion of the >10mRad chargeability signature increased the width of the chargeability anomaly significantly. All references to widths are approximate.
Survey Results:
Line-1 (Camp Zone): The chargeability signature covers a biotite quartz diorite intrusive and extends approximately 200m into a biotite granodiorite intrusive. The chargeability signature (>20 mRad) is generally vertical, approximately 700m wide, extends to a depth beyond 550m and is open along strike to the northwest toward the West zone. The historical drill holes (seven holes) in the vicinity of this line have returned significant concentrations of copper where sampled. The eastern portion of the chargeability signature is characterized by a 150m wide >10 mRad signature that is open to the east and to depth.
Line-2 (Camp Zone): The chargeability signature covers the biotite quartz diorite and is bordered on the east side by a broad (400m wide) >10 - <20 mRad signature. The chargeability signature (>20 mRad) is vertical, approximately 500m wide at surface and expands to 800m wide at a depth of approximately 300m. The signature is open at depth below 550m. The historical drill hole in the vicinity of this line has returned significant concentrations of copper where sampled.
Line-3 (Pass Zone): The chargeability signature is restricted to the biotite quartz diorite and dips to the east. This signature (>20 mRad) is approximately 400m wide at surface, increases to approximately 700m in width at a depth of 300m and is open at depth below 550m. The historical drill holes (four holes) in the vicinity of this line returned significant concentration of copper where sampled. The eastern portion of the chargeability signature is characterized by a 600m wide +10 mrad signature that is open to the east. DDH-32 tested the >10 mRad signature approximately 400m east of the >20mRad signature and was mineralized where sampled. This historical drill hole was completed under the new zone of oxide copper mineralization located east of the Camp and Pass zones in 2014.
Line-4 (Pass Zone): The chargeability signature is restricted to the biotite quartz diorite and dips to the west. This signature (>20 mRad) is approximately 400m wide at surface, increases to approximately 800m in width at 200m below surface and is open at depth below 550m. The historical drill holes (eight holes) in the vicinity of this line returned significant concentrations of copper mineralization where sampled. The eastern portion of the chargeability signature is characterized by a 400m wide >10 mRad signature that is open to the east.
Line-5 (Between Pass Zone and Bornite Zone): The chargeability signature is restricted to the biotite quartz diorite. This signature (>20 mRad) is approximately 500m wide at surface, increases to approximately 800m wide at a depth of 300m below surface and is open at depth below 550m. The historical drill hole (one hole) in the vicinity of this line returned significant concentrations of copper where sampled. The eastern portion of the chargeability signature is characterized by a 400m wide >10 mRad signature that is open to the east.
Line-6 (Bornite Zone): The chargeability signature is restricted to the biotite quartz diorite and displays a moderate dip to the east. This signature (>20 mRad) is approximately 600m wide at surface, increases to approximately 900m wide at a depth of 200m below surface and is open at depth below 550m. This line crosses the Bornite zone one of the two mineralized zones included in the resource estimate completed in 2012. The eastern portion of the chargeability signature is characterized by a 200m wide >10 mrad signature on the east and a 200m wide >10 mRad signature on the west side.
Line-7 (Between East Zone and Bornite Zone): The chargeability signature covers portions of the biotite quartz diorite intrusive and the hornblende quartz diorite intrusive. This signature displays a moderate dip to the east and is surrounded by the >10 mRad signature that measures 300m wide on the east and 200m wide on the west. This signature (>20 mRad) is approximately 600m wide on surface, increases to 1,000m at a depth of 200m below surface and is open at depth below 550m. This line is located between the Bornite Zone and the East Zone. These mineralized zones were included in the resource estimate completed in 2012.
Line-8 (East Zone): The chargeability signature covers portions of the biotite quartz diorite intrusive and the biotite granodiorite intrusive. This signature displays a vertical dip and is surrounded by the >10 mRad signature that measures 400m wide on the east and 200m wide on the west. This signature (>20 mRad) is approximately 600m wide, increases to 900m width at a depth of 400m below surface and is open at depth below 550m. This line is located on the East Zone that was included in the resource estimate completed in 2012. The first drill hole of the 2014 drilling program has been completed on this line.
Line-9 (Between East Zone and Far East Zone): The chargeability signature on this line is significantly different in shape and intensity compared to the chargeability signature on Lines 1 to 8. The chargeability signature has a vertical dike like shape that is approximately 200m wide within the biotite quartz diorite intrusive. This signature is surrounded by the >10 mRad signature that extends at least 400m wide on the east and 600m wide on the west. This signature (>20 mRad) increase in width at approximately 500m below surface is open at depth below 550m. There has been no drilling completed in the vicinity of this line.
Line-10 (Between East Zone and Far East Zone): The chargeability signature on this line resembles the chargeability signature on Line-9 and is surrounded by the >10 mRad signature that extends at least 400m wide on the east and 600m wide on the west. This signature (>10 mRad) is open at depth below 550m. There has been no drilling completed in the vicinity of this line.
Quantec Titan-24 Survey Parameters:
The Quantec Titan-24 DCIP system is a State of the Art geophysical tool used to explore for porphyry copper sulphide mineralization. The survey was completed on 10 surveyed lines spaced at 600 m line spacing. The Titan-24 survey typically images DC resistivity to depths of 500-750 m and the IP typically images to 500-750 m, in sub-vertical tabular geologic setting. The 3D inversion of the DC and IP data was completed using the UBC3D inversion code. The 10 and 20 mRad contours on the UBC smoothed, Half Space Referenced pseudo-sections were used to determine anomalous chargeability.
