MISSION DISCOVERY

Tombstone – NSAMT Lines, 1200m Elevation AnomaliesShallow weak conductor, possible epithermal gold-silver mineralization

Shallow moderateconductor, possibleburied dike

Shallow strongconductor, possibleburied intrusion

Old mine workings

Shallow gold-silver mineralization drilled by USMX

Large scale structures

Deep polymetallic CRD mineralization drilled by Santa Fe

MISSION DISCOVERY

Tombstone AMT 800m elevation depth slice

Moderate To StrongConductor, StrataboundAnd BelowHistoric Underground Workings

MISSION DISCOVERY

Tombstone AMT 600m elevation depth slice

ModerateConductor, <175 Ohms500m Across

MISSION DISCOVERY

Tombstone AMT, Line 3 InversionStrong Resistor, Interpreted asSilicified Sediments Above Dyke

Subvertical Moderate Conductor, Interpreted as Clay-Sulphide Altered Dyke

MISSION DISCOVERY

Tombstone - NSAMT Line 3 Pseudo-sectionShallow Conductor, possible cultural influence (eg. pipeline)

Moderate conductor 600m below surface, possible CRD massive sulfides

Strong conductor 200m below surface, possibly buried, mineralized intrusion, skarn

MISSION DISCOVERY

Tombstone AMT, Line 5 InversionModerate Conductor Interpreted as Sulphide Associated With Dyke

Spherical Conductor 350m Below HistoricUnderground Workings, Interpreted to Represent Sulphides

Strong Resistor: Interpreted as, Resistive, Weakly Altered Limestone

MISSION DISCOVERY

Tombstone AMT, Line 4 InversionShallow Resistor Interpreted to Represent Silicification

Subvertical Conductor, Interpreted to Represent SulphidesAnd Altered Dyke

Strong Resistor, Interpreted to Represent Granodiorite Intrusive
