331-C0016B-1L-1,0.0 | 0.00 | 0.00 | 331-C0016B-1L-1,64.0 | 0.640 | 0.640 | 0.0-27.0 cm: Hard black massive sulfide. Clastic textured black ore comprising rounded 1-5mm fragments of ~10% soft clay altered and ~10% hard siliceous volcanic rock cemented in a hard matrix of ~60% sphalerite, 15% pyrite, and quartz. | Coarser grained (2-3mm) sphalerite, pyrite, galena and possible chalcopyrite is associated with a late anhydrite vein down one side of section. 27.0-31.0 cm: WR sample (MB). Massive sulfide from XCT. 31.0-34.0 cm: Seimi-massive sulfide. | Hard, gray, strongly silicified interval with clastic texture almost obliterated by silificification. ~15% sphalerite, 10% pyrite. 34.0-64.0 cm: Hard black massive sulfide. | Similar to upper interval of section, with less abundant altered clasts (5%) and scattered irregular 2-4cm patches of pale clay with sugary quartz (possible late void fill?). Sulfide is more abundant: ~85% of total, with ~ half of this being pyrite. | 2010-09-30T23:35:59 | ||
331-C0016B-1L-CC,0.0 | 0.64 | 0.64 | 331-C0016B-1L-CC,15.0 | 0.790 | 0.790 | 0.0-15.0 cm: Hard gray strongly silicifed volcanic rock with ~5% coarsely disseminated 1mm pyrite and sphalerite throughout the body of the rock. | Coarser 2-3mm sulfide (pyrite-sphalerite-minor galena) is associated with a quartz-anhydrite-10% sulfide vein that runs from the top of the section to ~10cm (see core photo). | Fine 1-2mm wide irregular anastomosing veinlets of quartz with 10% sulfide also cut the rock. | 2010-09-30T23:49:47 | |||
331-C0016B-2L-CC,0.0 | 9.00 | 9.00 | 331-C0016B-2L-CC,31.0 | 9.310 | 9.310 | 0.0-7.0 cm: Hard gray strongly silicified volcanic rock with faint remnant clastic texture. ~5% pyrite and trace sphalerite disseminated as very fine crystals and scattered coarser 0.1mm euhdra throughout the rock. | 7.0-18.0 cm: Snow white coarsely crystalline anhydrite aggregate composed of 1-2cm tightly intergrown acicular crystals. Rough aligment of crystals in part of sample (orientation relative to core is meaningless, due to distruption). | Most of material is sulfide-free, except for a dark vein of 1-2mm euhedral spahlerite-minor pyrite which lies along one edge of the interval. 18.0-19.0 cm: WR sample (MB). Similar to overlying material. 19.0-20.0 cm: NO CORE. | 20.0-20.5 cm: WR sample (MB) Similar to underlying material. 20.5-31.0 cm: Subangular 2mm to 3cm (dominantly 5 - 10mm) soft gray clay altered and slighly harder white sugary silica-clay altered volcanic clasts are hosted in a dark hard siliceous matrix. | Fine grained pyrite is disseminated throughout the matrix, averaging ~3%, although the distribution is uneven. The clasts are also unevenly pyritic, containing up to 5% fine grained pyrite as disseminations and occasional vesicle fill. | The edge of an anhydrite-sphalerite-pyrite-trace galena vein runs along the top of the fragment - clearly trucnated by drilling, up to 1cm wide as exposed. | 2010-10-01T21:25:14 |
331-C0016B-3L-1,0.0 | 27.00 | 27.00 | 331-C0016B-3L-1,59.0 | 27.590 | 27.590 | 0.0-59.0 cm: Dark green to gray hard quartz-chlorite altered volcanic rock with abundant veining - stockwork mineralisation. Possible faintly defined fragments up to ~1cm in size, may be clasts, or fracture/veining generated. | Very fine grained pyrite is disseminated throughout the rock at trace levels. Including the veins, the interval contains ~ 5% sulfide. | Two generations of veining: Earlier sugary quartz-chlorite-pyrite veins form a network of 2-3cm wide veins, including a dark diffuse quartz- fine pyrite halo. | They contain euhedral pyrite up to 5mm in size in their cores, associated with green chlorite and sugary quartz. Later pyrite-anhydrite veins crosscut the quartz-chlorite-pyrite veins and lack halos. | They can be vuggy and comprise very coarse pyrite crystals (plus possible chalcopyrite - needs to be confirmed petrographically)) up to 0.5-1cm in size, with a sharply defined selvedge of anhydrite. | They vary from hairline (anhydrite only) to 1cm in thickness. | 2010-10-02T21:11:43 |

Possible faintly defined fragments up to ~1cm in size, may be clasts, or fracture/veining generated. | Very fine grained pyrite is disseminated throughout the rock at trace levels. Including the veins, the interval contains ~ 5% sulfide. | Two generations of veining: Earlier sugary quartz-chlorite-pyrite veins form a network of 2-3cm wide veins, including a dark diffuse quartz- fine pyrite halo. | They contain euhedral pyrite up to 5mm in size in their cores, associated with green chlorite and sugary quartz.

Not imaged by XCT, but visual inspection indicates that it is the same material as the rest of the core. | 2010-10-02T21:14:46 |
