The Gold Basin Mining District in Mohave County, Arizona has a long colorful history spanning back to the 1880s during the gold rush. There were many mining projects and workings warranting the construction of the Gold Basin Mill and San Juan Mill. The most prominent of the projects was the Cyclopic mine that was active through the 1930s. Historical Reports support that gold production occurred on the properties from the late 1800′s into the mid 1940′s
Modern development of the Gold Basin started with a New Zealand miner, Mr. Brown in the mid 1980s when he first started to investigate the Cyclopic Mine. In 1993 Mr. Brown formed the Nevada Pacific Mining Company to explore the property.
Aurumbank Incorporated was formed in 1999 and over the next 3 years maintained Nevada Pacific’s strategic land position. Aurumbank attained 5,200 acres from the BLM and an additional 5 parcels ranging from 320-640 acres from Newmont Reality Inc totaling the 7,670 acres, now under option by First Americas Gold.
Aurumbank began a large soil geochemical sampling program in early 2008 over many of the prospective areas within the Property before First Americas Gold optioned the properties in 2012. Soil samples were collected from the ‘B’ soil horizon every 100 metres along grid lines spaced 400 metres apart. A total of 87 line-miles (140 km) of survey control grid were established and surveyed using hand-held GPS units. The analytical results were interpreted by Dr. Jeff Jaacks, Ph. D., a qualified geochemist experienced with SGH geochemical surveying. He identified 5 significant targets, which were later resampled using conventional soil sampling methods, and the results showed a good correlation between the SGH and conventional soil geochemical results and the geological and structural settings within the surveyed areas.
See below for the location and details on the 5 significant targets:
Target 1: There is a strong northeast trending linear feature in the southern portion of the anomaly. The anomaly arcs to the northwest and west-northwest at the north end of the anomaly to the north of the Cyclopic mine. Copper and gold SGH signatures are coincident and overlie the Proterozoic intrusive margins, which have been offset by northwest trending strike-slip movement. Several northeast trending faults cross this anomaly. This area has the potential to host tensional lode gold veins hosted in the Proterozoic intrusive rocks which have been rotated to a northeast orientation by strike- slip movement along the northwest trending regional faults.
Target 2: SGH copper, gold and HA+HBA+LA+LB anomalies are coincident and extend from the margin of the Proterozoic monzogranite to the margin of the Proterozoic biotite granite. This anomaly lies within the northwest trending corridor formed by more recent Muddy Creek Fanglomerate. The area is crosscut by northeast faults which may act as a feeders to emplace gold mineralization within the Muddy Creek Fanglomerate which has infilled a pull apart basin created by the northwest trending faults bracketing the anomaly.
Target 3: The feature has lobes that follow northwest and northeast trending faults and contains at least one significant northeast anomaly indicated by SGH. The anomaly lies above the eastern margin of another area of Proterozoic monzogranite and extends northeast into the Muddy Creek Fanglomerate corridor. The anomaly is also bracketed by northwest trending regional faults and cross-cut by mapped northeast trending faults. This area has the potential to host lode gold veins developed in the margin of the Proterozoic intrusive and to the northeast within the Muddy Creek Fanglomerate.
Target 4: It trends north to south for 3 kilometers and is approximately 1 to 1.5 kilometers wide. There are northeast trending lobes in the feature and at least one significant northeast trend included within the area. The anomaly could be extended another 3 kilometers to the south as the anomaly follows the margin of the Proterozoic gneiss which has been placed in fault contact with the Muddy Creek Fanglomerate along a detachment fault. All of the SGH signatures are anomalous in this area and form the strong linear north-south orientation. The anomaly is cross-cut by significant northeast and northwest oriented faults. The area has potential to host lode gold veins within the Proterozoic gneiss and gold mineralization developed along and above the detachment surface within the Muddy Creek Fanglomerate.
Target 5: This anomaly overlies the P&LM Mine at the south end of the gas grid. It trends 1.5 kilometers from north to south and is 300 meters wide. The area has outcropping Proterozoic intrusive rocks which are covered by Quaternary alluvium filling northwest to southeast trending drainages. Copper and “Other” gold SGH anomalies are coincident. The dominant gas signature in this area is the copper signature which arcs slightly to the west and extends north. The copper and gold signatures together indicate lode copper-gold veins hosted in Proterozoic monzogranite which may be eroded to a deeper level where the copper becomes more predominant.
