Geology Comments

Dec 07, 2005 (S Fumerton) - There are a number of main parallel vein sets which trend 360/48. These veins are the axis for another en-echelon set of veins which trend 052/65. A conjugate pattern is apparent from the distribution of the quartz veins but there is little apparent deformation of the host rocks. The veins are braided with a 'pinch and swell' appearance.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - Original Comments are more than 2000 characters. The data cannot be converted, however the data will still be available in Digitial Prospector Database.

Dec 07, 2005 (A Wilson) - (PRECIS OF FUMERTON) The mineralization is hosted in a pillowed Fe tholeiitic basalt intercalated with massive flows and breccia units. Little deformation or alteration is apparent in these rocks away from the mineralized veins and the sequence strikes NW with tops to the SW. Massive mafic units with coarse biotite in the matrix contain quartz feldspar porphyry fragments. This unit is cut by the alteration and veining associated with the gold mineralization. Closer to the mineralized veins, carbonate alteration occurs in a zone up to 2 m wide on either side of the vein. There is a large body of lamprophyre associated with the mineralization. This body has intruded the mafic metavolcanics and is cut by the quartz veins and associated alteration. This unit has also been described as an altered diorite. The mafic metavolcanic rocks are cut by irregular felsic feldspar porphyry dikes, which appear to post-date some of the alteration, but are themselves partially altered. Large bodies of feldspar porphyry with 20-30% subhedral feldspar phenocrysts are found to the south of the veins.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Quartz veins which vary from 10 to 20cm occur in zones of strong carbonate alteration up to several metres thick. Parallel to the main veins within the alteration zone there are thin quartz veinlets. Within the main vein there are fractures perpendicular to the vein mineralized with carbonate and more rarely tourmaline. Brecciation of the wall rocks adjacent to the vein is common and the breccia has been infilled with quartz veining which appears to be part of the same phase as the main quartz vein. Fine grained pyrite occurs in trails along hairline joints - veins or along the contact of the quartz veins. In addition local pockets of coarse grained pyrite occurs in the less altered country rock and in the quartz veins. Pyrite typically forms between 5 and 20% of the carbonatized wall rock but locally forms up to 40% of the rock. Coarse subhedral galena is erratically distributed in the quartz veinlet stockwork that cuts the strongly carbonatized wall rock. Though the grains are hosted in the quartz veining the grains tend to be in contact with the vein walls. Molybdenite has been observed as medium grained flakes within hairline fractures within the wall rock adjacent to the veins together with some fine grained disseminated pyrite. Visible gold is erratically distributed in the quartz vein material and locally occurs in 'egg shaped' aggregates with spectacular concentrations of gold. Chalcopyrite, sphalerite, and specularite have also been observed.

Dec 07, 2005 (A Wilson) - There are five main veins in the vicinity of the #2 Shaft (#3, #8, #9, #11, #16 veins). Average gold grades obtained for each of these veins in 1933 were: 3.4 g/t Au over 117cm (#3 Vein); 1.7 g/t Au over 167 cm (#8 Vein); 17.5 g/t Au over 86 cm (#9 Vein); 8.2 g/t Au over 90 cm (#11 Vein) and 2.7 g/t Au over 123 cm (#16 Vein). Channel samples collected by the OGS in 1985 returned values of 0.045 g/t Au over 2 feet; 1.49 g/t Au over 4 feet, 0.415 g/t Au over 4 feet. Grab samples collected by the OGS in 1985 returned values of 24.2 g/t Au from a quartz vein. A muck sample taken by the OGS in 1993 returned values of 3.71 g/t Au and 1.6 g/t Ag. Sludge samples taken by the OGS in 1993 returned values of 2.18 g/t Au and 1.2 g/t Ag, 6.07 g/t Au and 1.2 g/t Au.

Geologist: J Ireland

Notes: The writer returned to the property with Chris Keech of Placer Development as part of a tour of the area. The Emerald Isle Resources camp was still in place but no workers were on site. A John Deere tire mounted backhoe and a D-6 Caterpillar tractor was also on the property. Considerable stripping and trenching had been completed just north of the No. 2 Shaft on a narrow vein system parallel to, and approximately 20 metres northwest of, the No. 9 vein. All of the trenches were filled with rainwater and the only exposure of this parallel vein was northwest of the shaft. Extensive stripping was also noted at the north end of the Northeast (No 9) vein extension, approximately 350 metres northeast of the No 2 shaft. Two new vein systems have been exposed running parallel to, and approximately 20 and 60 metres east of the Northeast vein. The veins have been traced for approximately 150 metres along trend and have extended the known systems on the Kenty property another 100 metres. The new veins are very similar in width from 5 to 50cm and made up of white-grey glassy quartz and minor rusty carbonate. A new tractor road has been pushed southeast approximately 1,550 feet from the north end of the Northeast vein to a small pond located in the north half of patented claim S.20715. Several trenches have been cut in the hillside along this road but at the time of the visit they were water filled. Stripping has taken place on a small promontory located on the northeast side of the small pond on claim S.20715. The tractor road continues around the north end of the small pond to the site of the No.21 vein located approximately 600 feet east of the previously described zone. No evidence of stripping on this was seen. [ PRECIS ]

Geologist: S Fumerton

Notes: Together with Bill Yee a visit was made to the property and were met by Mr Nick Bond. Mr Bond was supervising a three man crew stripping overburden and bulk sampling a series of quartz veins. Use was made of a John Deere 450 bulldozer equipped with front end loader and a backhoe together with an air compressor used for drilling and cleaning the outcrop. With this equipment quartz vein material is extracted from the outcrop and stockpiled prior to passing it through a test mill. The direction for blasting, trenching, and pitting is in part controlled by panning results on pulverized samples. There is a 5 ton per day portable mill on site. This is powered by a large portable generator and consists of:- 1) a small jaw crusher fed by the front end loader, 2) a second stage jaw crusher, 3) screens, 4) a ball mill, and 5) a large concentrating riffle shaker-table. The concentrate is shipped off site for processing. Permission was obtained to come back at a later date to sample the various stages from the open cut to the tailings pond.
