(918) 991-0524Inversion results and other 3D datasets can now have their internal geological plumbing analyzed in great detail. Explorers can gain a clearer picture of subsurface geological features modeled in their tenements. This is true 3D filtering of 3D data — and not simply a workaround involving the stacking of separately-processed 2D data slices. A southern Mongolian porphyry copper case study shows how.

Scene stitching

lovePatchwork mosaics of ASTER scenes and Landsat scenes often show boundary discontinuities that can be jarring. It's a situation that is avoidable, because our scene-stitching method converts a patchwork mosaic into a cohesive mosaic. Our method gives explorers access to remotely-sensed index images that are seamless. A case study in Arizona shows how. Read More 


3D deposit footprints thumbnail image3D deposit footprint modeling is a way of establishing clear and testable exploration targets from routinely-obtainable lithogeochemical data. Targets are not only defined by latitude and longitude, but also by depth. A porphyry copper case study in Peru shows how. Read More 

Seismic data analysis

409-654-8438Seismic imaging appears on the upsurge in mining and mineral exploration settings. Because the petroleum exploration industry spent decades honing the technique, explorers in hard-rock environments should be able to hit the ground running. We provide a look at a site amenable to the seismic method in a Western Australian case study. (304) 953-4144

Basement mapping

5052446835Depth-to-source maps can help steer mineral and petroleum explorers toward their preferred exploration depth, and toward basement morphology of exploration significance. Our case study, involving southeastern Australia's Bass Basin offshore region, shows how depth-to-source estimation can augment exploration efforts. 320-974-4445

Complexity mapping

Complexity mapping thumbnail imagePlaces where rocks have been put through the ore-mineralization wringer usually show signs of being relatively structurally complex. Find where your exploration tenements display heightened structural complexity. A case study of Ontario's Kirkland Lake region gives a taste of what's possible with complexity maps. Read More 


subanniversaryExplorers facing field reconnaissance need a firm grasp of the area's geology, a good first-pass map, and a means to help focus their work plans. Auto-mapping can supply all of these, because modern survey data are embodied in the resulting maps. A case study in Western Australia's western Capricorn Orogen region shows how. Read More 


(530) 797-1964Find where magmas or migrating fluids seem to have intruded and produced discrete, equant bodies. We show intrusion detection results for two case studies: the Ernest Henry IOCG deposit in Queensland, and the New South Wales copper and gold porphyry deposits of Cadia and Ridgeway. Read More 

Structure detection

804-348-6137Life can be messy and the process of doing a decent manual interpretation of mineral exploration data is no exception. A good way to cut through an information tangle is to employ map layers displaying your data's structural networks. Read More 

Demagnetization analysis

Demagnetization analysis thumbnail imageSometimes the important things don't always scream the loudest. If your targeted mineralization style is associated with overprinting processes such as metasomatism or hydrothermal alteration, it can pay to look for what's not there. Zones containing rocks that are relatively magnetically quiet can speak volumes. Read More 


647-519-0958In many cases you can successfully assume away the remanent magnetization of rocks in your exploration area of interest. But if strong remanence rears its head, run-of-the-mill magnetic survey interpretations become unreliable. We can detect where that's likely to be the case. (717) 479-0818

Constrained inversion

Constrained inversion thumbnail imageWhen explorers carry out above-ground gravity surveys, ideally they'd like a large density contrast between barren host rock and the mineralization they're targeting. But if the contrast is so minimal as to make mineralization essentially undetectable this way, all is not lost. Constrained gravity inversion may help in cases where below-ground measurements are available, such as drillcore or borehole density measurements. Read More 

Data decorrugation

Data decorrugation thumbnail imageSometimes geological features can be partly or totally wiped from geophysical data as an unintended result of standard decorrugation. Our alternative method removes undesired artificial corrugations efficiently but also maximizes the amount of geological signal left intact. (904) 775-3751

Grid stitching & merging

pedatedOur technique of rapidly and automatedly stitching and merging large gridded datasets permits the almost seamless joining of grid boundaries, even those that, with other techniques, are proving problematic. A case study shows how. Read More

Grid filling & extension

7207374421Data gaps in and around geophysical and other data grids often need filling. Popular methods currently in use have survived largely unchanged for decades. But given the increasing interest in segmentation and structural analyses of these datasets, gap-filling methods within the minerals exploration industry are likely due for a shake-up. 253-301-6685


Check out some of our results.

Exploration data in all of its forms — sub-surface, ground-based, airborne, and remotely-sensed — are representations of an area's geology, and its economic and environmental resources. The data can provide clues about ore deposit-forming and reservoir-forming processes, and about the status and availability of water before, during, and after the mine development phase.

The examples we present here show the results of some standard data-filtering routines, along with some advanced-imaging results.

Results such as those shown among these examples would typically be integrated with other information and expert knowledge, and interpreted with a view to generating recommendations, such as a ranked list of exploration targets. Typically included in such work would be a thorough report describing the work done and containing succinct, evidence-based conclusions, along with suggestions for any further avenues of investigation that seem warranted.

Fathom Geophysics

Fathom Geophysics Newsletter — Issue 25

713-431-1794The Australian mining sector is doing well enough, but according to our industry business-conditions snapshot the broader economy and Australian workers, households, and consumers seem uncomfortably perched on a knife's edge. We look at how glacial drift-derived sulfide grains can explorationally point the way toward possible mineralization. And we see how once-shunned rotational seismic waves have become the next big thing in seismology and beyond. Read More

Fathom Geophysics

Fathom Geophysics Newsletter — Issue 24

7406255843In our latest issue of the Fathom Geophysics newsletter, we show you that the Australian mining sector is riding high, according to our industry business-conditions snapshot. We also take a look at how Canada's Kidd Creek and Bathurst mining camps reveal important clues for explorers of volcanic-related massive sulfide (VMS) deposits. We see how a closer look at apparent mineral-chemistry trends at the Marathon copper-palladium deposit revealed them to be a mirage, but at the same time uncovered a legitimate exploration vector to mineralization. And we examine strategies for undertaking meaningful mineral exploration in the lateritic pediment-dominated landscapes of sub-Saharan West Africa. Read More

About Us

This is who we are.

In early 2008, Amanda Buckingham and Daniel Core teamed up to start Fathom Geophysics. With their complementary skills and experience, Buckingham and Core bring with them fresh ideas, a solid background in geophysics theory and programming, and a thorough understanding of the limitations of data and the practicalities of mineral exploration.

Fathom Geophysics provides geophysical and geoscience data processing and targeting services to the minerals and petroleum exploration industries, from the regional scale through to the near-mine deposit scale. Among the data types we work on are: potential field data (gravity and magnetics), electrical data (induced polarization and electromagnetics), topographic data, seismic data, geochemical data, precipitation and lake-level time-lapse environmental data, and remotely-sensed (satellite) data such as Landsat and ASTER.

We offer automated data processing, automated exploration targeting, and the ability to tailor-make data processing applications. Our automated processing is augmented by expert geoscience knowledge drawn from in-house staff and from details relayed to us by the project client. We also offer standard geophysical data filtering, manual geological interpretations, and a range of other exploration campaign-related services, such as arranging surveys and looking after survey-data quality control.

Meet our key people.

Amanda Buckingham, PhD
Principal Geophysicist
Daniel Core, PhD
Principal Geophysicist/Geologist

Here are their work backgrounds.

Amanda Buckingham:

Amanda has over 20 years experience as a geophysicist, working in exploration, consulting, airborne acquisition and academia. She has worked on projects on all continents, across a broad range of commodities and deposit styles.

Amanda has worked for majors such as Rio Tinto, and junior explorers like the Toronto-listed Geoinformatics Exploration. She began consulting with SRK in Perth, and developed her expertise in airborne geophysical data from several years managing acquisition projects with High Sense Geophysics in Toronto, and Fugro Airborne Surveys in Southern Africa.

Amanda's PhD at the University of Western Australia involved the design of enhancement filters and edge-detection programs for potential field data. These algorithms have made possible significant advances in methodology for the semi-automated interpretation of data.

Daniel Core:

Throughout the past 10 years, Daniel has been instrumental in developing Fathom Geophysics' trail-blazing in-house data processing software, and in making a licensed version of the software available to enterprising geoscientists in the minerals sector.

Alongside a three-and-a-half-year stint in targeting roles with the Toronto-listed junior Geoinformatics Exploration, Daniel has a year's worth of internships with the majors Conoco, Kennecott Exploration and ExxonMobil behind his belt. To date he has carried out field work in Chile, Mexico, Australia, the United States and Canada.

Dan holds a PhD in geology from the University of Michigan. During his doctoral research years he undertook project work with geologists from (then) Billiton, TeckCominco, PhelpsDodge, Asarco, Kennecott, and Codelco. His undergraduate degree covers the fields of geology and mathematics.
