A 2018 report when Graf was with Sumitomo:

Graf has identified a geophysical tool – controlled-source audio-frequency magnetotellurics or CSAMT – that is helping the exploration team see buried structures that commonly host gold veins. After taking a look at results from older surveys and comparing the results to where there is known gold mineralization, as well as where there is not, Pogo geologists knew they had a tool finding the types of structures known to host gold veins in areas where there is not a lot of surface indications of the precious metal. Graf requested a small CSAMT survey to be part of the 2017 program at Pogo but the mine's owners had bigger plans."Sumitomo came back and said, 'do the whole district," so we did a 120-line-kilometer survey last year," the exploration superintendent said. The results from this survey are helping Graf and the rest of the Pogo exploration team choose targets for an extensive exploration drill program slated for this year. Excited about Goodpaster Most of the 2018 exploration drilling will target two exciting prospects to the north of current mining – Fun zone extension, which lies west of the North zone and north of the Liese zone, and Goodpaster, a high-grade gold prospect north of the Goodpaster River that has a geophysical signature that indicates it could be up to 5,000 meters long.The Fun zone extension is a vertical structure that hosts mineralization that is different that what is typically encountered at Pogo. Despite these high grades and the Fun zone's proximity to the mill, the exploration team is even more enthusiastic about the potential just across the river." We are really excited about the Goodpaster right now," Graf . The first hole drilled at Goodpaster in 2017 tapped 22.8 feet averaging 0.103 oz per ton gold"We were pretty excited about that, being a mile or mile-and-a-half away from the Liese zone," said Graf. The team was even more excited about the 17.5 feet of 1.739 oz/t gold cut during the second hole drilled at Goodpaster. Graf said the core from these mineralized intercepts at Goodpaster looks identical to Liese, providing evidence that the two zones may have once been contiguous and have since been separated by a fault that runs between them along the Goodpaster River and the geophysical results indicate this Liese-like prospect could extend for 5,000 meters along strike. The geophysics that helped to identify them could be another tool for seeking other gold veins across the wider Pogo District.
