Sampling was also extended to cover the east and south part of the newerTRINI concession.Description of resultsIn general the gold background is 0-25ppb; high background is 50-75 ppb and anomalies at>100ppb. Anomalous gold content ranges from 100-300 ppb Au and >300 ppb, is evident at eachof the four zones described below and at other locations and at several other points on TRINI.Two known gold anomalous trends are related to the Las Colinas trend continuing northward, aswell as the further east trend from Mina La Colpa also trending northward. A large westernzone, called Fandango, shows anomalous gold and a possible related subzone or an extension,the La Virgen zone, also has a broad low level gold anomaly.Anomalous As, Ag, Pb, Sb, characteristic of the El Triunfo mineralization, occur in a zone withno outcrop, called the 602 anomaly, near the east side of the TRINI concession.In 2008 the geochemical data will be used to prioritize the various IP chargeability anomalies forfurther drill testing/trenching.10.3 GeophysicsThis section is extracted from a review of the 2006 and 2007 IP surveys by Reynolds(DGO ,2008); the sections in italics are extracted from Stephens, (2007).RIP (Reconnaissance Induced Polarization) surveys were carried out in mid-2006 by (DGO) ofDurango, CO, under the direct supervision of John Reynolds assisted by (DGO) fieldgeophysical technicians and by trained Pitalla field technicians. Several of the Pitalla fieldtechnicians had worked with Reynolds during the EBX generation of IP surveys, 1994 through1997. More detailed dipole-dipole and pole-dipole array IP surveys were carried out in 2007.Fig. 10.1 & 10.2 eliminated.2006 “A RIP (reconnaissance induced polarization) survey was done in mid-2006 as notedabove to determine if anomalous zones [identified during the late 1990’s by Echo BayMexico (EBMx)] continue northward beyond the known areas of mineralization. Resultsof the RIP survey ([stations are randomly spaced yet cover the aerial extend of theproject area]) showed two large polarization anomalous areas which extended off theCIRIO concession north and east. The central RIP anomaly was concluded to probablyconnect to the Las Colinas deposit area, while the eastern chargeable anomaly waslocated out east of the concession in the 602,000 east UTM coordinate”.DMBW have examined a DGO map which shows the RIP anomaly and contoured airbornemagnetic data. The airborne magnetic data is part of the EBMx data package acquired during themid-1990s. The output from the EBMx helicopter DIGHEM, which combined magnetic,electromagnetic, radiometric and VLF-EM data, are available through a data access agreementwith EBMx’ successor, Kinross Gold. [These airborne data were subsequently reprocessed by
