All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Analytical Data

Analytical Data: SATKOSKI AND SOKASKI REPORT ROCK SAMPLES FROM BOSTON NO. 2 CLAIM: #18, #19, FROM A SMALL PIT (THEIR FIG. 4, 5) WHERE ARGENTOJAROSITE MATERIAL IS EXPOSED: #18, A 10 IN CHIP FROM AN IRREGULAR LIMONITE SEAM IN LIMESTONE, .04 OZ/TON AU, 71.6 OZ/TON AG, 19 PERCENT CU
Analytical Data: #19 SELECTED LIMONITE FROM #18, .02 OZ/TON AU, 141.2 OZ/TON AG, .39 PERCENT CU. METAL CONTENTS OF 7 CHIP SAMPLES ACROSS A LIMESTONE BED WITH CHERT LAMINAE FROM THIS SAME PIT: 6 SAMPLES RANGED FROM 2.7 TO 14 PPM AG, THE 7TH SHOWED 230 PPM AG, 150 PPM CU, 1200 PPM PB, 760 PPM ZN. SAMPLES #20-22 FROM NORTH END OF AN ELONGATE PIT (THEIR FIG. 4, 6): #20, 30 IN CHIP THROUGH IRREGULAR LIMONITE ZONE, TR. AU, 16.9 OZ/TON AG, .14 PERCENT CU, .48 PERCENT PB. #21, SELECTED LIMONITE FROM #20, 20.6 OZ/TON AG, .57 PERCENT CU, 2.9 PERCENT PB. OTHER SAMPLES (#22 AND #23, 24) CONTAINED LESS AG, TWO CONTAINED ROUGHLY 4 PERCENT MN.

Comments

Comment (Development): SAMPLING (SATKOSKI AND SOKASKI, 1980). NEARLY ALL SURFACE EXPOSURES OF BRECCIATED, SILICIFIED AND LIMONITIC ZONES HAVE RECEIVED SOME EXPLORATORY ATTENTION.

Comment (Deposit): MOST BRECCIATED, SILICIFIED, AND LIMONITIC ZONES ARE WEAKLY MINERALIZED. SOME, HOWEVER, ARE HIGHLY MINERALIZED CONTAINING UP TO 141. OZ/TON AG (SAMPLE 19 OF SATKOSKI AND SOKASKI). MINERALIZED ZONES INVARIABLY HAVE SMALL LATERAL EXTENT.

Comment (Workings): SMALL PITS AND CUTS, ONE ADIT.

Comment (Location): PREVIOUS QUAD DESIGNATION = GRAND JUNCTION 1:250000

Comment (Geology): HOST ROCKS DO NOT APPEAR GREATLY DEFORMED, HOWEVER, THEY HAVE BEEN SUBJECTED TO SEVERAL PERIODS OF FOLDING, REVERSE AND NORMAL FAULTING, AND UPLIFT. IN GENERAL THEY ARE PART OF THE SNAKE RANGE DECOLLEMENT THRUST WITH PRINCIPAL MOVEMENT TO THE SOUTHEAST.

Comment (Deposit): JOHNSON CANYON HAS FEW EXPOSURES OF SILVER-BEARING ROCK, BUT MAJOR SUBSURFACE MINERALIZED STRUCTURES MAY BE PRESENT. HIGH SILVER CONTENT IN THE MINERALIZED ROCKS ON AND NEAR THE PATENTED CLAIMS IS COMMONLY RELATED TO BRECCIATION AND SILICIFICATION ALONG NORTH-TRENDING FAULTS. OTHER AG LOCALES ARE IN SILICIOUS LIMONITE ALONG BEDDING PLANES AND CROSS FAULTS, OR IN SMALL PODS, BUT MAJOR SUBSURFACE MINERALIZED STRUCTURES MAY BE PRESENT. NOTE: EVENING NO. 1 MINE AND EVENING NO. 2 MINE ARE ON THIS PATENTED CLAIM. ; INFO.SRC : 1 PUB LIT
