Carmax 2015 Program Extends Copper Mineralization on Pass Zone Including 0.47% CuEq Over 70.2 M
December 7, 2015
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 7, 2015) - Carmax Mining Corp.("Carmax") (TSX VENTURE:CXM) is pleased to announce the balance of the analytical results from the diamond drilling and sampling program from its 100% owned Eaglehead copper-gold-molybdenum-silver project located in northwest British Columbia. The 2015 program focused on the Pass zone, one of six zones of mineralization identified on the Eaglehead property. To view the location of the Pass zone discussed in this news release, visit the Carmax website atwww.carmaxmining.com.
- Significant copper mineralization has been outlined over a 1,000m strike length of the Pass zone;
- The surface mineralization in the Pass zone is Cu-dominated which overlies Cu-Mo-Au mineralization at depth;
- The 2015 diamond drilling and the sampling of historical drill holes have intersected or outlined multiple broad intervals of copper mineralization;
- Diamond drill hole DDH0126 intersected 0.14% copper, 0.010% molybdenum, 0.03 g/t gold and 0.70 g/t silver over a core interval of 162 m, starting at a core length of 234.0 m;
- Re-assayed core from DDH035 yielded 0.45% copper, 0.003% molybdenum, and 1.19 g/t silver over an interval of 70.42 m starting at a downhole depth of 11.58 m; and
- Several phases of the Eaglehead intrusive exhibit strong "Adakite" affinities typical of large porphyry copper deposits.
Jevin Werbes, President of Carmax stated, "We are pleased with the results of the 2015 program on the Pass zone. On a project scale, the data suggests a crude metal zonation from Cu-Mo in the East zone to Cu-Au in the Bornite zone to Cu in the Pass Zone over a horizontal distance of approximately 3.5 kilometers. The near surface mineralization is Cu-dominated which overlies Cu-Mo-Au mineralization at depth. Major and trace element modelling suggests that Eaglehead is a multi-intrusive complex with several of the intrusive phases exhibiting an "Adakite" signature typical of large porphyry copper systems. This supports our interpretation of a large multiphase porphyry model for the Eaglehead property."
The weighted average grade of the mineralized intervals from the 2015 drilling and sampling program from the Pass Zone are outlined below:
|Zone||DDH#||Azimuth||Dip||From (m)||To (m)||Interval (m)||copper (%)||molybenum (%)||gold (g/t)||silver (g/t)|
Notes: DDH035 includes an interval of 6.02m with no core available for re-assay. The mineralized intervals in DDH036 starting at 56m includes an interval of 7.52m with no core available for re-assay. Zero metal values were assigned to these intervals in both drill holes. Where possible, historical assays were included in estimating the average grades provided that no overlap in interval or grade occurred. The core intervals in the above table do not represent true thickness. Numbers are rounded for presentation purposes. Molybdenum values below 0.003% and gold values below 0.03g/t are reported as trace ("tr"). See section below for metal prices and metal recoveries used to calculate copper equivalent (CuEq).
Summary of Results
The 2015 program covered a 1,000m portion of the Pass Zone. Diamond drill holes 125 and 126 were completed in 2015. The other analytical results reported from the Eaglehead project in 2015 were obtained by re-logging and sampling of historical diamond drill holes previously completed on the property.
The copper mineralization in the Pass Zone occurs in moderate to strong potassic and phyllic altered biotite granodiorite, hornblende quartz diorite and Quartz Feldspar porphyry dikes as chalcopyrite +/- bornite hosted in fractures, veinlets and as disseminations. Molybdenite occurs in late quartz veinlets and quartz veins. Intervals of higher grade copper mineralization are characterized by late stage intense potassic alteration and bornite.
The study of porphyry copper systems has evolved to the point whereby using the chemical makeup of an intrusive rock, geologists can distinguish between intrusives that have a higher probability of forming a porphyry copper deposit compared to barren non-mineralized intrusive rocks. Intrusives having unusually high contents of Silica (SiO2), Aluminum (Al2O3), Strontium (Sr) and Vanadium (V) and unusually low contents of Scandium (Sc), Yttrium (Y) and Titanium (TiO2) are referred to as exhibiting an "Adakite" affinity. Adakite like rocks are indicative of intrusions that have potential to form large porphyry copper and porphyry copper-gold deposits.
Modelling of the chemical characteristics of the various intrusive phases at Eaglehead shows that three of the five intrusive phases mapped at the Eaglehead project exhibit strong Adakite affinities.
Diamond Drilling and Sampling Procedures
DDH0126 were completed using NQ core size. DDH's 014, 35, 36 and 48 are BQ size core. In DDH 126; after cutting with a diamond saw, one half of the core was collected for sample preparation and analysis and the other half was retained for future reference. For the BQ size core, the core was split using a mechanical splitter with one half the core being sent for analysis and one have the core being retained for reference purposes. Where only one half the core was present in the core tray, that one half core was collected and submitted for analysis. Sample intervals were selected based on lithology changes/alteration intensity/estimated mineral content. The sample interval where possible was maintained at 2.0 m . Sample preparation and analyses were completed by SGS Canada in Burnaby, British Columbia.
The base metal contents of the samples were determined using SGS Canada's 4-acid digestion and ICP-ES finish. Copper values in excess of 8,000 ppm were assayed. Silver values are determined with a lower detection limit of 0.01g/t Ag. Gold content was determined using the fire assay method on a 30-gram sample followed by ICP-ES finish; with a lower detection limit of 0.005 g/t Au. SGS Canada has a 17025 ISO accreditation.
Copper equivalent calculations are based on recoveries of 100% of copper, 74% of the gold, 73% of the silver and 60% for molybdenum. Metal prices are copper $US2.75/pound, gold $US 1,445.00/ounce, molybdenum $US14.00/pound and silver $US20.00/ounce.
Carmax follows a rigorous Quality Assurance/Quality Control program consisting of inserting standards, blanks and duplicates into the sample stream submitted to the laboratory for analysis.
