Mining Chip Sampling

Chip sampling in underground mines. Underground mining procedures are collectively known as drift mining where applied to placer gravels.

A A single chip sample line divided into a central vein sample with associated hanging and footwall samples.

Mining chip sampling

. 1168 gpt Au and 3339 gpt Ag over 45 m and 570 gpt Au and 2920 gt Ag over 60 m. Face photographs showing sample lines based on geology. Sample intervals are set at a specified width usually ranging from 1 to 20 feet commonly 5 feet.

Sawn channel sampling uses a rock saw to provide a high quality sample that is comparable in accuracy with good-recovery drill core through the same zone. The current chapter overviews the most common techniques that mine geologists are using for sampling mine workings for delineating ore bodies estimating reserves or need that samples to control grade and metallurgical characteristics of the excavated ore. It is typically used to sample exposure in mine openings or.

Rounds grab sampling of stockpiles field sampling of RC chippings or laboratory sampling of crushed Figure 1. Is pleased to announce additional assay results at the Benjamin Hill property comprised of the Sonora Gold and Sonora Copper concessions. In 1993 samples collected from the re-excavated Trench-21 on the Main Shear zone reportedly returned 127 grams per tonne gold over a true width of 441 meters British Columbia.

Surface trench TA-TR-3b positioned oblique to the mineralized structure returned 178 gpt Au and 710 gpt Ag over 630 m 241 m true width including two high-grade intervals. A total of 447 chipchannel samples. This method is used only in a preliminary investigation.

Vancouver British Columbia--Newsfile Corp. The shape of grid is adopted to the morphology and structure of deposit. While it is more expensive and requires more equipment than rotary air blasting its accuracy makes it one of the most popular mining exploration drilling techniques.

Drift mining presupposes the concentration of values in a well defined stratum or channel. SAMPLING IN GEOLOGY. Chip or point sampling The method is less laborious and used as a regular method of known samples is used for hard or uniform ores where it is difficult to cut channels.

In this method the samples are collected by taking a small series of chips of rocks on a regular grid pattern from the working face in regular intervals. Benjamin Hill Mining Corp. The results are unrepresentative of the actual state of mineralization.

It is primarily used for investigation. The objective of sampling in mineral processing is to estimate grades and contents of sampling units in an unbiased manner and with an acceptable and affordable degree of. The tools are used hammer and chisel.

It gives the confidence necessary to proceed to drilling. The sample is then placed into the top sieve with a small garden spade. A detailed chipchannel sampling survey is also planned for the Main Shear Zone at the Trench-21 area.

Other mining sampling methods are bulk sampling channel sampling and chip sampling. Generally sampling is the art process of selecting a part of a whole such that the measured value for the part is an unbiased estimate for the whole. The results of all these methods are combined in order to determine the grade of the ore body.

The blasted broken material are sampled. Sampling in the Mining Industry starts with exploration and continuous through grade control mining metallurgical process laboratory and ends with the final precious metal product. The sample is sieved on-site using a 80 mesh sieve 178 micrometres using a stack of sieves with progressively finer mesh sizes.

Outcrop Chip Sampling at the Dominion Property Returns Grades of 349 Grams Au and 176 Grams Ag per Tonne. B Dual face chip sample lines across a sheeted vein zone. Drift Mine Sampling.

The objective of this survey is to confirm reported gold grades. Placers buried under deep masses of low-value gravel or capped by lava flows have been extensively worked in this manner. Benjamin Hill Mining geologists continue to advance mapping and chip sampling for mineralization at Caracahui Sahauro and Sonora Copper mineralized areas.

At Tim historic trench chip samples returned 3524 gt silver 912 lead over 4 m and two grab samples taken from another trench returned assays of 12481 gt silver and 495 lead and 9787 gt silver and 32 lead respectively. The main advantage of this sampling. Grab sampling is often a double check on the chip or channel sampling methods.

Chip-channel sampling aims at providing an approximate indication of width and grade of an identified zone of interest. This method is used to take samples from an outcrop. RC drilling allows for uncontaminated chip samples and can be used in all formation types.

Alianza believes the property has the potential to host a carbonate replacement manto style deposit similar in nature to the nearby Silvertip mine owned by Coeur Mining. Samples taken at the surface fresh and clean. A soil sample ready to be sieved.

François-Bongarçon 2008 described how sampling became an irrevocable part of the Mining Industry. Surface rock chip sampling at Tahonitas is designed to map the surface expression of mineralization. Nicola Mining Inc.

This coarsest sieve removes organic matter such as leaf litter and charcoal as well as coarse sand and gravel. When chip channel sampling is conducted along a rock face often a piece of canvas or plastic is laid out for the material to fall on so as to avoid contamination and make the collection of the sample easier.
