Despite the preponderance of gold-mining and railway-themed illustrations that appear on this site,  I have been known to draw other things, especially aircraft. Herewith an example.

GOLD MINING

11. A CALIFORNIAN 5-STAMP BATTERY...DSCF3393 (2)

‘A ‘CALIFORNIAN’ TYPE  5-STAMP BATTERY AS USED ON N.Z. GOLDFIELDS’. 

In most of the Coromandel Peninsula’s batteries (reduction-works), the stamper battery was the key to success.   The battery  invariably  operated in  groups of five (as illustrated).* Heavy weights (the ‘Stamps’),  operating  in a pre-programmed sequence and set at  the optimum height for the purpose, crushed the gold-bearing quartz-rock to talcum-powder fineness, releasing  the gold there-in for further chemical processing.

* Confusingly, in Australasia, the term ‘Battery’ was / is used to describe both the crushing  machinery (as illustrated), and the building / site where these machines were located.

GOLD MINING

‘Art’ takes many forms, not all of them necessarily mono-dimensional.  For many years I have been a model railway enthusiast, using 1: 148 scale (‘British’ N-scale) to reproduce in miniature the sorts of things that could be seen in the ‘full-sized’ world.  An example of this appears below. It depicts the battery (also known as a ‘reduction-works’) of the Kaisers Reef (Hauraki) Gold Mining Co. Ltd.   In common with many of my efforts it is fictional in concept, although based on actual similar plants and is technically-accurate in what it portrays.   It is included for your viewing pleasure as it is a verifiable ‘work of art’ , albeit in three dimensional form; the colours and techniques used in creating the model forming (at least in my opinion) a cohesive whole, and contributing to the over-all narrative.

Herewith two images for your delectation. I trust that you will enjoy them.

GOLD MINING

2. DRILLING HOLES FOR EXPLOSIVES DSCF3031 (2)

Compressed-Air Drill

In underground goldmines, the gold was contained within quartz rock , known as ‘reefs’.  The reefs had to be broken-up and to do this required the use of explosives, placed into holes drilled into the quartz rock.  Compressed-air was used to drive the machines used to drill these holes.   The image above shows two men using a rock drill (based-on the Edgar’ patent) with light being provided by candles  placed in holders (known as ‘spiders) inserted into the walls of the working. This image  is a study in shadows.

Note: Drawn with a pigment liner with an 0.3 mm nib, on cartridge paper.  Image measures 3.5 in x 4 in. (76 mm x 114 mm).
