Wildcat Silver changes name to reflect growing interest in lead, zinc

Arizona Geology Blog - Tue, 2015-06-09 06:17

Interesting news item that Wildcat Silver Corporation has changed its name to AZ Mining Inc.  The new website is
The company said the change "reflects both the Company's focus on its Hermosa property located near Patagonia in southern Arizonaand the poly-metallic nature of the mineralization on the two current projects."   

Richard Warke, the Company's Chairman and CEO said, "The recently released drill results from the first five holes on our Hermosa North West drill program confirm we have the makings of a potentially significant zinc/lead/silver deposit on our hands. As a consequence, we felt this was the right time to re-brand the Company given its current focus on North West and our history and commitment to mineral exploration in Arizona."

Sunset Crater, San Francisco Volcanic Field

Arizona Geology Blog - Thu, 2015-06-04 16:53
Sunset Crater is the youngest cone in the San Francisco volcanic field in northern Arizona.   Over the past 6 million years, more than 600 volcanic cones formed, with an eruption every 3,000 years on average.   Sunset Crater may have erupted during the winter of the year 1064-1065.  The erupted materials are alkali olivine basalts, which may have erupted over a 10 year period.

No volcanic activity at Sunset Crater according to Park Service

Arizona Geology Blog - Thu, 2015-06-04 15:37
The National Park Service issued a news release this afternoon in response to an internet claim that a steam cloud was produced by Sunset Crater near Flagstaff.  NPS stated " activity has been observed on the ground by park rangers staffing the National Monument."

We're in contact with the NPS, National Forest, National Weather Service, county officials and no one has seen any evidence of activity.  The purported plume coincided with smoke being carried from a controlled burn in the forest a few miles upwind of the site.  

NPS made a good point in that each of the 600+ cinder cones in the field are one-time events, so reactivation after nearly 1,000 years would be unprecedented.

Here's the full NPS announcement:

"Steam plume" from Sunset Crater is likely just smoke from forest fire

Arizona Geology Blog - Thu, 2015-06-04 11:51

A report of a purported "steam cloud" from  Sunset Crater near Flagstaff appears to be mis-identification of a smoke plume from a Forest Service prescribed burn near A-1 Mountain a few miles to the southwest that passed over the crater, or possibly an orographic cloud formation in the lee of San Francisco Peak.
County, state, and federal officials in the Flagstaff area all report that there is no steam or any other activity at the Crater.  There is no earthquake activity in the area on the state seismic network that we maintain.
An internet site from Missouri and its YouTube post is getting a lot of online attention and prompting calls to AZGS as well as to local and national government offices over its "Arizona Volcano Alert" posting based on seeing a smudge on a low resolution satellite image.  That claim is being spread across the web as a volcanic "ash cloud" or actual volcanic eruption.
Sunset Crater erupted about a thousand years ago, and there is no evidence of modern activity.    So, as exciting as it might be to have an eruption in our backyards, it just ain't the case folks.

Thanks to our colleagues at the National Weather Service, Coconino National Forest, Coconino County Emergency Services, National Park Service, and State Forester's Office, for tracking down the real story.
