Diamond Joe Mine Report (1957)

SUBJECT: Emmons & Krug Property near Wickenburg, Arizona

On March 10th I visited the lead-silver property owned by Lawrence Emmons and Robert Krug, situated approximately 10 miles northeast of Wickenburg, Arizona. I was accompanied on this examination by Mr. Robert Krug.

This property has been taken up with eight unpatented claims. Outcrops of the vein can be traced for about 1500 feet on the surface on the Calcite #1 and #2 claims. On the Calcite #1 claim several hundred feet of mining has been done, apparently many years ago, but no records of content, etc. seem to be available. The mine at one time- was known as the "Diamond Joe". The vein runs north and south and dips approximately 55 degrees to the west. Samples taken of the outcrop near the mine and 1500 feet south, show the following results: #1--Au--Tr., Ag--3.3oz., Pb--1.1%, Mo--1.06% #2--Au--Tr., Ag--5-Ooz., Pb--Tr.

A sample taken near the mine dump of a 1/4" size crushed ore pile, gave the following assays: Au--.030z., Ag.--10.6oz., Pb--l.8%.

East of the Calcite claims outcrop another similar outcropping was examined on the Kilroy #1 claim which lies parallel to the Calcite #1 claim. Some mining was done on this claim as was evidenced by the stripping of a couple of feet of the outcrop and the stockpiling of some of the ore. This property was known as the "Great Southern", and as in the case of the "Diamond Joe" no records are available. Grab samples taken over approximately 100 feet of the outcrop gave the following assays: Au--.0loz., Ag--0.8oz., Pb--0.20

The outcrops on the two claims are not related on the surface and no faulting appears to be in evidence. Mineralization is contained in a limestone formation bounded by pegmatites in a barren schist. The limestone outcrop that was sampled was approximately 18" to 24" wide with some mineralization showing on the pegmatite walls. Minerals recognized in the vein were cerussite, galena, wulfenite, fluorite, cerargyrite, barite, and calcite.

This property was probably mined at one time for its high-grade silver content but shows no promise of being a profitable venture except on a small scale chloride deal.
