| NPA
provide a complete service for mineral exploration from data
acquisition, through processing and interpretation to digital
map production, with particular expertise in structural geologic
interpretation. This includes the ability to generate regional
lithostructural maps and undertake alteration and mineral mapping
to aid target generation for ground follow-up. NPA have worked
in recent years for companies such as Anglo American, Rio Tinto
and BHP Billiton. |

| From
the reconnaissance stage of exploration through to mine development
maximum use should be made of remote sensing data. |

Placer Deposits |
| Beach
sands and alluvial deposits are well known targets in the exploration
of heavy minerals. NPA have used both Landsat and radar satellites
to map not only present day drainage patterns but also palaeo-drainage
and shorelines. |

| Spectral
mapping using satellite imagery can be used to outline and differentiate
lithologies and mineral suites. |

Working
in a GIS & in 3D |
| Representations
of digital elevation data can be greatly improved visually by
draping satellite imagery over the terrain, creating realistic
3-D views. |
