(Depth: 675 ft.)


The ‘Featured Image’ for 18 April 2016, is of the surface workings and machinery associated with the Te Kereru [Tea Care-Rare-Roo] Mining and Investment Co. Ltd.’s  Toi Toi  (Toy Toy) shaft, (currently 675 feet, deep).  The  surrounding Toi Toi mine workings are also visible. The Toi Toi shaft Poppett Head (Head Frame) is visible to the right rear of the image, with the shaft Winding Engine House (and chimney from the adjacent boiler house) is visible in the immediate foreground.  In the rear of the image, the adit portals of various other workings are visible.  From Left to Right these are :   No.4 (visible at extreme left of image); No.6 (behind crane); No.5 (behind Popett Head.  No.3 adit is immediately behind the chimney, but is obscured by the latter.  The original (and now closed) No.1 working is visible at the top of the image at a point above and to the right of the Winding Engine House chimney.

The ‘Featured Image’ For 11 April 2016

Dear Reader:  Welcome back to the nzcrownmines.wordpress.com blog page.

As you will be aware by now, I do have a slight interest (some would suggest a ‘passion’), in gold-mining, specifically, underground gold mining as practiced on New Zealand’s Coromandel Peninsula (the ‘Coromandel’ being that narrow point of land that sticks up from the country’s North island and runs roughly parallel to the location New Zealand’s largest city, Auckland.

I am also a historian and someone who ‘plays’ (according to some) with ‘toy trains’ 9the subject of another blog ‘sometime’ in the future.

Inevitably, these three interests (gold mining, history and model railways) have come together and as a result, I have, over time, built various mining-themed model railways.  These have been in ‘N’ scale (1:148), HOn3 (1:87) and .009 (also 1: 48)., with the latest being a 1; 148 scale (aka UK-N scale)  one named Te Kereru Mining and Investment Co. Ltd. ( Te  Kereru  BTW, is pronounced Tea Care Rare-Roo).

Essentially, the layout focuses on gold mining operations and the movement of trainloads of ore from the mine to the crushing plant/ reduction-works / battery (the terms are interchangeable but I will use ‘battery’ in this instance as it is in common usage throughout Australasia).  The actual layout will probably make its appearance on these pages in the future, but for the moment I will be focusing on the battery; the subject of this blog (yes, we are getting to the ‘Featured Image’ – it’s just taking a while).

The image appearing as a ‘Featured Image’ (I hope) is reproduced below and shows only part of the battery.  The photo consists of  three basic components; the battery building (the sloping building in the background), the ‘Spitzluten’ (or Hydraulic Classifier) (the yellow ‘table’ appearing on the left centre of the image) and the cyanide plant.  The cyanide plant consists of the tanks being ‘filled’ in the  lower part of the image and the tall structures (aka ‘B&M’, ‘Tall’ or ‘Pacchucca’ tanks) to the rear of the right rear of the  image.

These structures were the focus of the extraction process and as such were extremely important to the individual mining companies.  They were also developed in New  Zealand with the B&M tanks being a New Zealand  invention, being patented in 1909.  The other structures in the image also relate to the cyanide process, the long pipe visible running across the lower right centre conveying waste water to a nearby tailings dam.

Trusting that you, Dear Reader, have found what you have read and seen to be of interest.

I look forward to posting more things for your delectation in due course.

An Apology

11 April 2016

To those who may have been wondering why there has been a ‘great silence’ at nzcrownmines.wordpress .com for several weeks, I can only tender my apologies, and thank you for your patience.  Unfortunately, due to circumstances beyond my control I could not access my site, and as a result, was unable to continue with my posts.

HOWEVER the issue appears to have been resolved, so, without further ado, I declare that nzcrownmines.wordpress.com is back ‘on air’.

Again, thank you everyone.

Now, to find some images…. 🙂
