COL-Magnet Copper-Gold Porphyry Project

canada_britishcolumbia

After careful analysis of the results of the 2007 and 2008 drilling campaigns Solomon terminated the option agreement on the central Col Mineral Claims held by Nation River Resources Ltd. and Indata Resources Ltd. in December of 2008. Solomon has retained a significant mineral tenure position that it acquired east and west of the option ground and is awaiting further developments in the Mt. Milligan – Kwanika area before committing to further exploration on these claims.


The COL-Magnet Copper-Gold Porphyry Project is located 140 kilometers north of Ft. St. James, British Columbia and 45 kilometers northwest of the Mt. Milligan Copper-Gold Deposit. The COL-Magnet property is geologically similar in both regional setting and mineralogy to the Kwanika Project of Serengeti Resources Inc. located 35 kilometers to the northwest.



Solomon optioned the Col-Magnet Property on December 12th, 2006 from Indata Resources Ltd. and Nation River Resources Ltd. and has acquired additional prospective ground to the east and west of the option area.



The COL-Magnet property is situated within the central portion of the Quesnel Trough, a 30 to 60 km wide by 1,300 km long depositional basin which extends northwest from the southern British Columbia border (49th parallel) to the Stikine River in Northern B.C.
Potential for the discovery of alkalic porphyry +/- Cu-Au-Ag-Mo deposits, such as Afton and Mount Milligan, is considered to be good within the Quesnel Trough, especially in areas of favourably developed structural control.

The Col-Magnet property lies within the Hogem Intrusive Suite, consisting of a quartz deficient suite of monzonite, quartz monzonite, granodiorite, diorite and syenite, probably of early Jurassic age. The Hogem intrusive is best described as a suite rather than batholiths, due to its inhomogeneity.

The intrusions range in composition from Hornblendite/ pyroxenite, through to syenite. Many bodies are hypabyssal and porphyritic. The bodies range in size from tens of metres to tens of square kilometres in size.

Coarse grained monzonite is restricted to the Hogem intrusive suite, the intrusion on Mt Milligan and the Max Pluton. It is this coarse grained crowded porphyry, consisting of felsic minerals, poor in mafics that is key to finding mineralized deposits. The predominant texture is 1 to 2 mm plagioclase feldspars, loosely touching each other to create a fine grained intrusive texture. Hornblende, clinopyroxene and biotite may be present. The fine grained groundmass consists of plagioclase and potassium feldspars, with minimal quartz. Texturally, these rocks are between intrusive and extrusive. Dating of the crowded monzonite places it at the early Jurassic age, +- 188-204 Ma.

An early mafic phase extends from Kwanika creek to the north shore of Chuchi lake. The Chuchi monzonite varies in texture from coarse grained to medium grained salt and pepper texture, to porphyritic. Diorite is also present. The main mafic minerals are clinopyroxene and biotite. Coarse grained equigranular monzonite dominates the next phase and extends from the Kwanika creek area to the shores of Chuchi lake.

The youngest pluton of the intrusive is the Chuchi syenite. It includes pink syenite and quartz syenite, with upto 7% quartz. The predominant texture is medium grained, equigranular to aplitic. Hornblende/ biotite range from 2 to 10 %. Medium to coarse phases with orthoclase are present, suggesting the orthoclase was on the liquidus when the syenite was forming. Dykes of syenite cut through the property, and xenoliths of monzonite are present. The syenite was the last phase of the Hogem Intrusive and has been dated at 183 Ma.

All of the economic finds to date are associated with alkaline shoshonitic suites of late Triassic, early Jurassic age, and with cogenetic alkaline intrusions. Many of the gold-copper porphyry deposits occur in and around sub volcanic intrusions. The host monzonite is typically the crowded monzonite type. Intrusive breccias and diatremes are also an important aspect of these systems. In the porphyry systems, contact metamorphism, as expressed by flinty biotite hornfels, is extensive compared to the small size of the intrusions that core the aureole. Propylitic and potassic alteration assemblages are superimposed on contact metamorphosed country rock and also occur in the monzonite. Abundant secondary magnetite, part of the potassic mineral assemblage, makes airborne and magnetic surveys an important exploration tool.

During the 2007 exploration season, the property was explored with an aeromagnetic survey, extensive soil geochemical surveys, stream sediment surveys, geological mapping and drilling of 14 diamond drill holes totalling 2,500 meters.



Five targets were identified for diamond drilling in 2008.

A drill program comprising 1,043 meters of "NQ" series diamond drilling in eight holes was completed on five discrete drill targets:

  • The VG Showing targeted the original Campbell trench area which had reported copper values of 4.88% and gold values of 2.4 grams/tonne in historical rock samples. This area was also identified in the 2007 program as an EM geophysical anomaly;
  • The Sleeper Copper-Molybdenum North Pluton, which had been identified by 2007 program soil geochemistry as containing 854 ppm (parts per million) copper, and 25 ppm molybdenum;
  • The East Tackla Site which targeted a 2007 EM geophysical anomaly as well as soil geochemistry values of 2089 ppm copper;
  • The Sleeper Pluton, also a 2007 program EM geophysical anomaly;
  • The East Ridge, identified by the airborne survey as being a magnetic high, and localised copper-gold soil anomalous values of 412 ppm copper and 23 ppb (parts per billion) gold.


The best intersection in the 2008 diamond drill program was from the VG showing where DDH-2008-1 intersected 0.43 % copper and 0.51 grams/tonne gold from 17.0 meters to 47.0 meters depth (a 30 meter intersection.) This mineralization was found within highly potassic altered dykes hosted in biotite-hornblende monzonite. Sulphides consist of bornite, pyrite and minor chalcopyrite.

Drilling by Solomon in 2007 reported an intersection of 0.60% copper and 0.14 to 0.32 grams/tonne gold in the "A Zone" over a true width of 25 meters, with a down dip extent of more than 180 meters. (Solomon News Release dated January 21st, 2008.) DDH 2008-1 is located approximately 1 kilometer from the "A Zone" along a separate sub-parallel structural trend.

Solomon's President Randy Rogers observes: "The similarity in geological and regional setting to the nearby Mt. Milligan deposit of Terrane Metals Corp. with published reserves of 334 million tonnes averaging at 0.217% copper and 0.428 grams per tonne gold (Terrane Feasibility Study - Technical Report dated April 14th, 2008) suggest that the mineralization associated to the Hogem Batholith is extremely complex. Our exploration efforts over the past two seasons have returned some intriguing mineralized intersections and added to our understanding of the structural controls of mineralization on this property. A number of viable exploration targets remain to be followed up."
