New Sidings at Murrobro (Blayney)

Location: Blue Mtns
A rail train will run next monday to deliver second hand rail for new sidings (3)on the Down side at Murrobro, near the BIG FRIDGE, they will be built for an ore set up that will arrive on road containers and be hauled to I think, Port Kembla for export, and there is also a siding for the BIG FRIDGE, but rail wont be used there yet.

Cheers

Should that be "Murrobo" bro?

So will this be in addition to the ore setup in Blayney itself or will it replace it?

Yes. Murrobo is a new dewatering facility to replace the current one in Blayney.  Total project cost estimated about $6m (including upgrade for the transit systems at the mine.

The ore comes from Cadia, which is funny itself  as it had its own branch until a few decades ago that went off near Spring Hill. It was closed down as mine back then was not doing much.

They now expect about 27 million tonnes of ore to be moved per year for the next 21 years.

27 million tonnes a year??? Are you sure???

Thats a huge amount. A quarter of the entire output of coal in Newcastle!

A more likely figure would be 27 million tonnes over the life of the mine, transported over 21 years. Still, thats just over 1.28 million tonnes a year. Perhaps it's 2.7 million tonnes over the life of the mine, with 128k p.a. transported?

It's quite likely that I've missed the mark altogether!

Sorry just to clarify, they will mine 27 million tonnes per year, only the ore ore concentrate is transported.

Either way It does seem just a 'little' too much, even to mine 27 million tonnes per year in an open cut mine would leave a big dent in Central NSW.

However, that is what they place on the proposal. See dot 2 on page 2 of the application:

Just had a look at the project description and it shows the following:

2.9.3
Concentrate Load-out
The concentrate load-out process would be as per
the current process employed at the Blayney
Dewatering Facility. A front-end loader would be
used to load dewatered concentrate from the
stockpile into containers for rail transport. The
containers to be used would be approximately 6.5 m
long, 2.6 m wide and 1.8 m high and have a carrying
capacity of approximately 26 t of mineral
concentrate.

A container forklift would transfer the filled
containers from the load-out area to hardstand
areas in readiness for loading onto a train. The filled
containers would be loaded onto train wagons via
the container forklift with two containers per wagon.

2.9.4 Mineral Concentrate Product
Transport
It is anticipated that approximately six trains per
week would be required to transport the concentrate
from the CVO Dewatering Facility to the eastern
seaboard for export. Each train would be capable of
carrying up to approximately 68 containers.


So thats 6 trains per week each carrying 68 containers.

Would the new siding be a loop on the single line between Murrobo and Blayney, or would it be some other arrangement?

The new Cadia East development is truly a massive deposit.

The total resource (normaly slightly larger than the mining reserve) is 2347 million tons at 0.44 g/t Au and 0.28% copper.

The reserve is 1073 million tons at 0.6 g/t Au and 0.32%.

At those grades, everything has to be on a large scale, hence the large annual ore tonnage.

The orebody will not be an open pit, rather a "panel cave" - essentially that means they will develop in under it from under ground, in a series of panels that will then cave (no need to drill and blast) once they are established. The caves will eventually propagate to surface in a roughly 60 degree cone.

The size of a 1000 million ton orebody is roughly 300m wide, 1200m long and 1000m deep.

The milling rate is roughly 26 million tons per annum but at those grades the concentrate will be much, much less.

The copper mineralisation is principly in chalcopyrite and bornite, this are the minerals that are concentrated, as well as gold, and some waste pyrite.

A typical concentrate grade might be 25%, or perhaps slightly better.

They plan to produce 100,000 tons of copper per annum. (you dont need to worry about the wieght of the gold, 800,000  ounces is slightly less than 25 tons).

That suggests an annual output of concentrate around 200-400,000 tons.

It would appear this was a relatively short branch.

Following is my 'rail summary' of the Cadia East proposal from the original document - which answers awsgc24's question about the siding .......

" constructing a new dewatering facility east of Blayney and decommissioning the existing Blayney Dewatering Facility; "
 into the "Public Files" section - then Determinations .....NB the major projects website has changed since I wrote this file note....the following web link is unchanged

http://majorprojects.planning.nsw.gov.au/files/46085/Director-General's%20Assessment%20Report%20-%20Low%20Resolution.pdf

page 10 ( of PDF) 50

Construction
•a new dewatering facility to the east of Blayney (to be known as the CVO Dewatering Facility) and a 1.7 km rail spur from the Main Western Railway to the new facility;

Picture on page 9 of 50 ..... rail spur straight past the front of Blayney Sealink shed's.

page 11
Concentrate Transport and Dewatering

Construction of a new CVO Dewatering Facility to the east of Blayney and eventual decommissioning of the existing Blayney Dewatering Facility if it is deemed by Cadia to be redundant

Installation of a new concentrate pipeline to the CVO Dewatering Facility

Increased rail transportation to reflect increased production

page 13


The proposed rail spur extension traverses land zoned 1(a) General Rural, 7(a) Environmental Protection and 2(v) Urban/Village under the Blayney LEP. The rail spur extension is permissible with consent in all these zones.


page 32

Rail Noise
The project would increase rail movements on the Main Western Railway from 3 to 6 movements a week. Given that the operations would still typically generate only one project-related train movement per day, the Department is satisfied that the project would not result in any significant rail-noise-related impacts. Notwithstanding, the Department has recommended a condition requiring Cadia to investigate ways to reduce rail noise associated with the project.


Thats all the references to the word "rail" by "Adobe search.

I haven't yet read the Modification to this plan which is the link johnboy provided above... Wink

Do you call 18km a short branch?   A nine page article on the line appears in the January 1971 issue of the ARHS Bulletin (now Australian Railway History).   The line, which used to branch off at Spring Hill, was opened in 1918 and finally closed in 1945.  The Company had its own locomotive, a Clyde-built version of a 30 class tank, and was named "Iron Duke".   After the line's closure, the loco was transferred to Australian Iron & Steel at Port Kembla.
