Hannan Metals Limited is pleased to announce the commencement of a 40.6 line kilometre 2D seismic survey at the 100%-owned County Clare exploration license, which hosts the Kilbricken zinc-lead-silver deposit, Ireland.
The survey will cover the most prospective areas within the 32,223 Ha prospecting licence area, and is designed to identify and map the geological structures that host and control base metal mineralization.
- A 40.6 line kilometre 2D seismic survey has commenced across Hannan's County Clare 100% owned prospecting licence area, employing the latest seismic geophysical exploration techniques used by the oil and gas industry;
- The survey will extend from the Kilbricken zinc-lead-silver resource area and will extend over an area of 12 kilometre by 14 kilometre within the Clare Basin where potential is very high for additional base metals discoveries (Figure 1);
- Seismic is not a technique commonly used in hard rock mining and is more popular in the oil and gas industry. Hannan is one of only a handful of exploration companies to use the method globally;
- The survey has the potential to propel understanding of the regional geology of the Clare Basin in a technological way, not previously possible. The survey aims to map subsurface structures that may host mineral deposits, allowing for highly effective drill targeting when used in combination with other data.
Mr. Michael Hudson, CEO and Chairman, states: "The application of an innovative technology such as seismic to our exploration program provides Hannan the opportunity to greatly accelerate discovery rate at our County Clare zinc project. Hannan is one of few hard rock companies to apply seismic surveying to mineral exploration globally. The geological data collected will allow our geological experts to identify structures that may host base metal deposits in the both the local area surrounding the Kilbricken resource, and beyond over a large regional area."
The seismic survey was designed by Hannan, together with its geophysical consultants and is being carried out by Gallego Technic Geophysics and Rees Onshore Seismic Ltd. A total of 34 people are currently at site in Ireland performing the survey. The operations have been permitted by the Clare County Council and comply with all relevant central and local government regulations. Three north-south lines and one east-west tie line is planned to test for structures in multiple orientations (Figure 1). The survey will run until the end of November.
Seismic surveys use sound waves to map features beneath the earth's surface. A convoy of specialized vehicles (Vibrators) (Photo 1) generate the sound waves which travel through the earth and are reflected back to surface from geological layers. These faint echoes are recorded by sensors (geophones – Photo 2), which are then processed to produce images of the underlying geological layers and structures. The seismic technique has advanced rapidly over the recent years as researchers adapt and introduce new methods, algorithms and approaches with increasing computing power (Photo 3).
