Copper deposit 2 in Kuala Lumpur 

By Denzil Albert 
Furhter to Mr Sia's article, since I live at Taman Desa, I was observing while taking the Danau Desa exit, that the colour of the water of the SMART holding pond (the old Taman Desa tin mine) was slightly greenish.

Driving my discovery, into the back of the lake with it's still fresh from previous construction and flood debris, I got to the runoff tunnel. This is a huge tunnel.

As the weather today and yesterday was dry I was able to observe the deposits left by the flowing waters towards the lake. While predominantly laterite wash.. they are tinged with green deposits. Since copper is likely to be quite heavy and this lake has been flooded quite a few times even before the SMART tunnel was constructed being in close proximity of Sg. Kerayong, there must be depostis of copper here.

Since I am no geologist but understand basic science, I was able to do some scientific research on the net.

Given that the lake edge bed is quite old, some biomineralization may have occured thus I postulated further concentrating the copper. As biomineralization produces ferrous iron see http://www.scq.ubc.ca/the-little-workers-of-the-mining-industry/
which then produces mineral sulphides, I bought a gardening pH kit from Ace hardware and tested the water. And what do you know Walla...a somewhat acidic pH of 4 which explains the absence of fish in the lake and a concentration of copper. Now we must calculate the potential value of this...

No need to go knocking down our great Klang Gate quart ridge nature reserve, given the Taman Desa lake is shaped like an upside down cone, volume is approximated as 1/3 (pi)(r^2)(h). With this formula we can calculate the volume of the lake bed.

Using my trusted black and decker laser measuring tool, I noted the radius of the lake to be 238 meters. Pointing the laser down in the water I approximate the depth around 50 meters. digging up some old masterplan documents that came with my dads house S&P (circa 1975), the old land records from the early days of taman desa suggests that this mining pond is actually about 230 meters deep. Which means 180 meters must be deposits.
This gives 10677133 cubic meters of ore, given that some bioleaching must have happen, it must be at a very high concentration.

Since I am no goelogist, I take 8% as reference in Mr Sia's article as a guesstimate of the yield. This gives 854170 tonnes of copper worth USD 7 billion!.

Shall we stake a claim?
