After 119 years, the Northwest Mining Association has chosen a new name to better reflect the fact that it now boasts 2,400 members from 42 states, seven Canadian provinces, and ten other countries.
Following an 18 month review and input from its members, the association has changed its name to American Exploration and Mining Association. The organization plans to continue its mission of educating the public and policymakers about the importance of the mineral industry.
The new web address is www.miningamerica.org and this change, together with the new name, is now reflected in the right-hand sidebar section titled Clubs and Organizations.

USGS Quadrangle Maps Get a Major Re-Do
With winter seemingly approaching an end, some of us may be thinking about the coming season's prospecting opportunities. One of the essential tools for exploring the back-country in search of valuable mineral deposits is a good map. For many years, the U. S. Geological Survey's 7.5' quadrangle maps have fulfilled this role. Graphically displaying landforms, elevation contours, streams, lakes, and other bodies of water, as well as roads, trails, selected buildings, and other man-made features (including mines!), these maps have proven indispensable for staying oriented and on track in the wilds.
In 2013 the USGS began phasing in a significant design change for the venerable 7.5' quadrangle map. The new design incorporates information from The National Map databases to produce a digital quadrangle map with increased accuracy and selectable layers showing orthoimagery, transportation features, geographic names, topographic contours, boundaries, hydrography, woodland, structures, and the United States National Grid. The Public Land Survey System, with its townships and sections, is in the process of being added to these maps. In order to keep the maps as current as possible, the orthoimagery base layer will be updated at least every three years.
These digital maps are available online for free download as PDF files with a geospatial extension and are known as Geo-referenced PDFs (or GeoPDFs). Most map files seem to run about 20MB in size and can be opened with the free Adobe Reader or any other PDF reader that shows layers. (For the illustrations in this article, I used the free Nitro Reader 3 software.)
As an example, consider the GeoPDF for the Monte Cristo, Washington, quadrangle with all data layers turned on:
On the left-hand side of the image you can see the layers menu, which allows you to control the information displayed on the map.
To better see the detail, let's look at an area on the map showing the junction of Silver Creek with the North Fork of the Skykomish River:
The contour lines and other map features are superimposed on the orthoimagery, which gives a very good idea of terrain as well as the ground cover. While the imagery layer may give a good idea of what the countryside looks like when viewing the map on a computer, it would probably not be suitable for a printed map to be used in the field. We can create a map without the aerial image by unchecking the orthoimagery layer in the PDF. The result, reproduced below, would easily show compass bearing lines, GPS way-points, and other marks the user may wish to add while using the map outdoors:
Although one can order paper versions of these maps from the USGS, the ones I've seen all show the orthoimagery layer. While these maps would probably make handsome display items if framed, as mentioned above they would probably not be suitable for work in the field. Add to that the fact that they cost (as of this writing) $15 each and you have another incentive to look for an alternative.
The practical alternative is to print your own maps showing only those data layers you want. The best way I know to do this on a printer that only accommodates paper up to letter size is to use the
"Tiling/Poster" setting in the printer driver menu. (Check your printer manual for how to access this feature.) With my Canon MG2200, the 'Printer Properties" menu containing this setting is accessible from the PDF viewer application. This setting divides the image into multiple parts, each of which prints on its own page. The setting usually also provides an option for printing "Cut/Paste" lines in the margins of the sections to aid in taping them together. If your printer doesn't have a "Tiling/Poster" setting and you don't have the rather expensive Adobe Acrobat application (which incorporates this feature), you may be able to find a free software application that will allow you to perform this operation. One option for Windows might be PosterPrint. I haven't tried this software, so proceed with caution if you opt to use it.
If you are using Adobe Reader to view these maps, there is a free extension for it called the TerraGo Toolbar which you can download and install. This toolbar allows you to perform a number of special operations with the map, such as finding coordinates, measuring lengths and areas, tracking the current position of an attached GPS unit, adding notes, lines, shapes, stamping information onto the map, etc. I haven't tried this feature yet so can only go by the descriptions of its operations provided by the USGS.
In addition to the US Topo series of maps, all USGS previously issued topographic maps are available for free download from the same source as the new maps.
The US Topo mapping program is an ongoing project with more features to be added as time goes on. Incidentally, Washington is one of the states scheduled for updating in 2014.
Below are links to resources for obtaining and using these maps:
Select and download US Topo and historical topographic maps.
Factsheet on the US Topo map series.
Quickstart Guide for using US Topo maps and historical topographic maps.
In addition to the links listed above, I have updated the link to the USGS Store in the MAPPING APPLICATIONS & ONLINE SPACIAL DATA section of Resources for Prospectors in the right-hand sidebar to provide access to both the new US Topo and all the historical topographic maps.

1620 74th Avenue SW, Tumwater, WA.
According to the summary on the Commission website, the proposed changes to the rules are:
Multiple sections have been combined into a single section. A new section on mineral prospecting on ocean beaches has been added, including where beach prospecting may occur and what equipment may be used. The provisions for mineral prospecting on ocean beaches prospecting are included in the Gold and Fish pamphlet. Authorized work times for mineral prospecting in Nooksack and Wenatchee Rivers have been changed and are listed in a table. The timing in the Nooksack River changes from July 16 – August 15 to submit application. The timing in the Wenatchee River from the mouth to Leavenworth changes from July 1 – July 31 to July 15 – September 30 and from Leavenworth to Lake Wenatchee changes from July 31 [Sic...July 1] – July 31 to July 15 – August 15.

New Mineral Prospecting and Mining Rules Proposed by WDFW
We've seen this before and what a fight
it was last time!
The current Gold and Fish
pamphlet containing the rules for mineral prospecting and placer
mining was developed in 2008 and took effect in April, 2009.
Significant input from the Small Scale Prospecting and Mining
Community had a large impact in making the rules workable, if not
altogether ideal, for miners. It now appears that the rules are
about to change again for the worse unless we take immediate action.
One disturbing aspect of this change is
the announcement in an email from the Resources Coalition that WDFW
is no longer seeking the cooperation of the Small Scale Prospecting
and Mining Community in the development of the new rules that is now
underway. Below is the Resources Coalition email reproduced with
permission:
![]() |
| Click above images to enlarge. |
As mentioned in the above email, WDFW
has scheduled a public meeting to focus on the proposed changes to
the mineral prospecting and placer mining rules. When and where is
as follows for this event:
When October 23, 2013 6:00 P.M. to
8:00 P.M.
Where Natural Resources Building
Capitol Campus
NRB Room 172
Olympia, Wash.
Some of the proposed changes that are
outlined in the HYDRAULIC CODE RULE CHANGES Draft Programmatic
Environmental Impact Statement are the following:
Existing WAC Numbers: WACS
220-110-200, 220-110-201, 220-110-202, 220-110-206 are to be replaced
by Proposed WAC Number: WAC 220-110-300. The document notes on page
35 that,
The rules adopted by the Washington
State Parks and Recreation Commission allowing certain beach
prospecting activities in marine waters are covered by the Gold
and Fish pamphlet so an individual HPA to legally prospect on
ocean beaches is not required. Timing change to the Nooksack and
Wenatchee Rivers reflect the results of spawning surveys.
(Emphasis
added.)
Multiple sections have been
combined. A new section on mineral prospecting on ocean beaches has
been added, including where beach prospecting may occur and what
equipment may be used. General requirements for mineral prospecting
are included in the Gold and Fish pamphlet. Authorized work
times for mineral prospecting in state waters have been changed and
are listed in a table.
(Emphasis added.)
On page 47 we learn that the Existing
WAC Number WAC 220-110-020 is to be replaced with the Proposed
WAC Number WAC 220-110-030 and that,
Definitions have been separated into
three categories: general terms, mineral prospecting specific terms,
and aquatic plant removal and control specific terms. Existing
definitions have been updated and new
definitions have been added. (Emphasis added.)
The present author has not had time to
scour both old and new lists of definitions but would caution that
significant changes could lurk there.
On page 97 of the Draft EIS we are
treated to a list of the Potential Impacts to Fish Caused by
Mineral Prospecting:
-Injury/mortality
-Degraded physical habitat (spawning
substrate)
-Reduced prey availability
-Reduced productivity
Please note that
all of these “potential impacts” are probably as speculative as
they sound since no credible data are presented that any of them
actually result from small-scale mineral prospecting or mining.
Please note further that all of these impacts are of a negative
nature, omitting such reported benefits to fish as mercury removal from
streams that occurs as a result of suction dredging.
In any event, there
is much to contest here and members and supporters of the Small Scale
Prospecting and Mining Community are well advised to attend the
Olympia meeting in droves lest we find our property rights and
livelihoods steamrolled by environmental special interests.
Comments on the
Draft EIS must be received by WDFW no later than 5:00 P.M. on
November 15, 2013. WDFW states that,
You
can submit your comments any one of the following ways:

Playing Chicken? -- Armed Federal/State Environmental Task Force Invades Placer Claims Near Chicken, Alaska
From the Alaska Dispatch:
Miners from the Chicken area -- a gold mining town of just 17 full-time residents and dozens of seasonal miners off the Taylor Highway, between Tok and the Canadian border -- said that during the third week of August they were surprised by groups of four to eight armed officers, who swarmed onto their mining claims with little or no warning.
The officers were armed and wearing body armor. They were part of the Alaska Environmental Crimes Task Force and were there to check for violations of section 404 of the Clean Water Act, according to several miners who were contacted by the group. Section 404 governs water discharges into rivers, streams, lakes and oceans.
The task force’s methods are now being questioned by the miners as well as the Alaska congressional delegation.
One of the questions that ought to be asked of these agencies is if they are intentionally trying to provoke a violent incident involving miners in service to some unacknowledged agenda?

Are We Recreational Miners? -- Not if We're Smart!
As readers of this blog have probably noticed, it is dedicated to the small-scale miner and prospector. There is a good reason to abide by this terminology, as illustrated in the following development reported on page 7 of the August issue of the Western Mining Alliance Newsletter.
It so happens that on August 28, Santa Barbara County Superior Court Judge Frank J. Ochoa denied the petition for an injunction to halt California's ban on suction dredging. According to the "Legal Update" printed in the newsletter, in order to obtain the injunction the miners needed to show, among other things, that they would be irreparably harmed by the ban. To quote from the article:
Judge Ochoa took the position we haven’t demonstrated sufficient harm to warrant an injunction. This ruling was based primarily on the 2009 Suction Dredge survey which the State presented as evidence.
The Suction Dredge Survey sent out in 2009 as part of the Environmental Impact Report had 668 people respond to it. Of that number 82% labeled themselves as recreational dredgers. (Emphasis added.)
This recreational dredging term resulted in the judge deciding a recreational activity couldn’t suffer irreparable harm and denying the injunction
While there is some room for hope in reversing this ruling in that it ignores the plight of the 18% of respondents to the Suction Dredge Survey who did not identify themselves as "recreational" dredgers and who may well qualify as suffering "sufficient harm" from the ban, the cautionary tale to be learned here is that we are professional or semi-professional miners who enrich ourselves through our mining activities which, enjoyable as they may at times be, are not "recreational" in nature. Given the court ruling cited above, we might do well to heed the advice in the WMA Newsletter and "strike the term 'recreational' from (our) vocabulary."
The Western Mining Alliance Newsletter is well worth reading. The current issue may be found on the organization's webpage here.

Southern Oregon Miners Sue to Stop Anti-Mining Legislation
According to Oregon Live, the Galice Mining District in southern Oregon has filed for an injunction in the U.S. District Court in Eugene to stop consideration of bills in the Oregon Senate that would place a moratorium on motorized mining in Oregon waterways.
There seems to be some question whether the court will act to stop legislation that has not yet been passed into law, although the answer may not be long in coming. In any case, it is evident that the miners of southern Oregon are keeping a close watch on threats to their livelihoods and are not afraid to take action to protect their rights; something the rest of us in the mining community would do well to emulate.
For complete details on this story, please visit the link here.

Google Earth Overlays Show Washington Geology by County
The Washington State Department of Natural Resources has announced the availability of 39 .kmz files that will allow users to view the state's surface geology information as 1:100,000 scale overlays in Google Earth. According to the announcement:
Users can take advantage of functionality native to the Google Earth program, such as terrain generation (pseudo-3D visualization), overlays, and transparency, while using place markers and other Google Earth features to which they are accustomed. The overlays provide geologic information such as age of rock units, presence of major faults, and basic lithology, giving users the ability to observe Washington geology and how it interacts with land features.
