RE:RE:Why the big drop? From the posted link:
"The Philippines has ordered the suspension of 20 more mines for environmental violations, as the world's top supplier of nickel ore vowed to pursue stricter standards than in global mining centers such as Canada and Australia."
"Most of the mines were nickel producers and the news sent global prices up more than 1 percent on Tuesday, helping the metal recover from earlier losses amid worries over disruption of supply to the important Chinese market." "Among those ordered suspended were nickel miners Marcventures Mining and Development Corp and Carrascal Nickel Corp. OceanaGold Corp, the top gold miner in the Philippines, was also facing a suspension.
Jasareno said the audit on OceanaGold's Didipio gold-copper mine showed "damage to houses allegedly caused by blasting and perceived dangers of underground mining". OceanaGold CEO Mick Wilkes said in an email to Reuters that there had been no environmental violations.
Shares of the Australia-listed miner fell 8.2 percent, prompting the firm to request a trading halt.
OceanaGold later said it had not received a suspension order and that mining was continuing and it would work with the environment agency to avoid any disruption."
No mention of BTO, at this point. Hopefully, they have kept their environmental noses clean. If they have, this might be a nice buying opportunity.
