Copper in Florence Arizona - Taseko

Teseko - TKO.t ($ 1.78) has been trying for 6 years to obtain an aquifer permit for an in-situ copper recovery (ISCR) operation. Used mainly for uranium extraction, the company has long touted ... "where a mixture of 99.5 percent water and 0.5 percent sulfuric acid dissolves copper into the bedrock. Then the copper solution is pumped to the surface and processed into copper cathode sheets. The pH of the water and sulfuric acid solution is similar to that of “common household vinegar.”

This is only half correct. The company plans on recycling the raffinate, meaning the solution grows in concentration with each and every pass through the rock. When eventually processed it will be much more than "household vinegar".
From 1996 to 1998, the BHP Copper company developed the project on what is now part of Florence Copper’s site. They conducted a 90-day pilot test to see if the in-situ method worked on the site. Stacy Gramazio, Florence Copper’s manager of communications and public affairs, says that that test was successful.

And that is a dead deliberate lie. Even after being rinsed for over 22 months after a 90 day test more than 20 years ago, those holes still are still reporting unacceptable 'exceedances'. And the reason? Almost certainly because the copper ore is very highly radiometric ... so radiometric that they are the highest levels found anywhere in Arizona.
Bottom line? It was scientifically proven that the ISCR process WOULD leach highly radioactive contamination into the groundwater. (In fact every ISCR ever constructed has corrupted ground water) Has that stopped Taseko and their mindless paid minions?

There is NOTHING comparable to the extremely high concentrations of radiochemicals at the Florence Copper project. (Table 18 page 49)

The take it to the bank, black and white conclusion of the experts at the EPA and ADEQ? " data indicate that the PLS produced from the Magma Florence in-situ projects contain very high levels of radionuclides and that they are leachable."

Gemstones of Zambia

Zambia has the second largest deposits of emeralds in the world and accounts for about 20% of global supplies.

Zambia also possesses Africa's largest deposits of amethyst and some of the best aquamarine in the world.
Unfortunately the country has failed to benefit from these gemstone riches. There’s minimal employment creation. Most of the mines are not owned by Zambians and tax revenue is virtually non-existent.

Many mines in the country operate without a license and smuggle stones abroad. Stones are nearly always unprocessed and don't fetch good prices, as compared to cut and polished products.

The uncontrolled sale of gemstones and lack of accountability are just a few of the challenges being faced.

The open-pit Kagem mine. White pegmatite veins cut across the country rock.
In April 2016 the Zambian government banned the overseas auctioning of gemstones. In November plans were announced for a gemstone trading system to create a platform for buying and adding value to Zambian gemstones.

The opencast Kagem mine is producing between 1 and 3 million emerald carats a month.
Despite protests the new framework appears to be working so far. A low grade rough emeralds auction realized US$15.2 million which was the highest value ever realized. A July auction of high grade emeralds brought US$31.5 million and was the best ever in terms of value per carat sold. All of the 583,448 carats placed on offer changed hands.
