I am amazed at the lack of credibility in some of the government agencies (geared towards the USGS). The last 2010 USGS Silver Mineral Yearbook showed the following top 25 silver producing mines in the United States in 2010.
You will notice as of 2010, the RED DOG MINE was the number one silver producer in the country beating out HECLA’S GREENS CREEK. However, this is simply not true.
You will notice as of 2010, the RED DOG MINE was the number one silver producer in the country beating out HECLA’S GREENS CREEK. However, this is not true. Teck who runs the Red Dog mine does not give out their silver production. So, the Alaska Dept of Geology has to do the calculation themselves. They do an excellent job. All the USGS has to do is call them up and ask for the figures. Both the 2011 USGS SILVER YEARBOOK & ALASKA MINERAL REPORT are not yet published.
If we look below at the next two tables from the 2010 ALASKA MINERAL REPORT, we will see the exact silver production coming from RED DOG and GREENS CREEK;
If you look at the top table which is the RED DOG MINE, you will see that they produced 6.78 million oz of silver in 2010. The Alaska Dept of Geology calculates the silver from Red Dog’s lead production (where most of the silver is contained). The second table which is GREENS CREEK, shows that they produced 7.2 million oz of silver. This is also in Hecla’s 2010 annual report. Green Creek produced 400,000 more oz than Red Dog, but according to the USGS, Red Dog was the larger producer. Go figure…
Regarding rising zinc and lead ore grades at Teck’s RED DOG MINE. If we look at the Q2 2012 report we see the following:
