MRA embarks to reduce mercury usage
Alluvial miners at work on Bougainville

The Mineral Resources Authority (MRA) recently launched a project to reduce the use of mercury in small scale mining operations.
The Project aims to identify the extent to which mercury is used in the industry and how it is used and by whom, in a bid to mitigate health risks.
On March 6th, the ‘Reducing Mercury Use in Papua New Guinea’s Alluvial and Small-Scale Gold Mining Sector’ Project was launched in Port Moresby, following a workshop with key stakeholders and project partners.
The Alluvial Mining industry is one of the largest small to medium enterprise sectors in PNG that engages thousands of rural small scale miners.
It is also a sector that is great health risks due to the usage of mercury.
“This project is designed to get a better understanding of our alluvial sector general, and more specifically to identify the extent to which mercury is used how it is used and by whom,” said MRA Executive Manager of Regulatory Operations, Roger Gunson.
“In addition, it will track the supply trial and identify the regions where it is used. The data collected relating to the sector will be entered into a database administered as part of MRA’s land-folio tenement system.
“This will be able to better inform on policy development, resourcing, training and sector needs.”
Gunson, said the Alluvial Mining is one of the biggest revenue earners for the country with K550 million recorded in 2019.
He said this is similar to revenue generated by smaller mines such as Simberi Mine. However, the use of mercury in extracting gold poses major health risks to the miners.
“Unfortunately, in many parts of PNG gold is extracted through the use of mercury. This is a danger to the health of miners, their families and communities as well as we have heard from the workshop today.
“Hence, we have a paradox, we want the gold and we want to be able to seek it, but we also have a health risk that sits alongside it,” said Gunson.
The project is funded by the US Department of State and implemented by Artisanal Gold Council (AGC) in conjunction with the MRA.
And here was me thinking the 22" Concentric X-coil is a massive coil People looking skyward in Central NSW might think they've seen a UFO if they catch a glimpse of the state's newest mining tool. It's an Aerial Electro Magnetic array called the 'X-cite' - and the exciting part is it's finding gold way out west.
Gold facts/information Quote then add your facts
A cubic centimetre of gold weight 19.3 grams
A cubic inch weight is 10 ounces
Gold is Au and silver is Ag
Atomic n° of gold is 79 (Au79)
Silver is a better conductor of heat and electricity than gold but gold does not oxidize.
Gold is soft, dense, malleable, ductile
Gold is malleable enough for just 1 gram to be hammered into a sheet 1 square meter in size.
The melting point of Gold is 1,064.43°C (1,947.97°F).
100% of gold found naturally is isotope Au-197.
187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons)
gold is “diamagnetic”, meaning that it can be repelled by a magnetic field, but cannot form a permanent magnet.
United States. Tonnes: 8,133.5 in 2020

The first Gold coins appeared around 700 BC.
An ounce can be beaten out to 187 square feet (about 17 square metres)
1870s until World War I the gold standard was the basis for the world’s currencies.
Gold was the international monetary system, it came to an end by the 1970s
Gold occurs mostly in the native state, except with tellurium, selenium, and bismuth.

I'm having a discussion with an engineer friend about gold. I am of the contention that there has been much more gold mined and found than what is reported. Well ... what is my starting report? Let's go with this one as I don't really know how to prove or disprove my assumption. I don't want this to be 'consensus science' which is in vogue right now but I guess without true gold facts there has to be a certain amount of belief in known gold produced each year and reserves in conjunction with industrial and aesthetic uses over all time on earth. I don't really care about how much is left or not mined or in reserves.
I found this statement when I did a Google search:
Between all of the gold sources in the world, current estimates suggest that roughly 2,500 to 3,000 tons of new gold is mined each year. At present, experts believe that the total amount of above ground gold in the world stands at just over 190,000 tons. The source of this statement is Provident Metals. Is this over or under?
