The cost for the seismic survey represented a huge saving in time and money over an intrusive borehole survey while providing more meaningful and consistent information The Results: The seismic refraction survey completed by SUMO was highly effective in showing three geological layers, one of soil, one of conglomerate and then a layer of limestone bedrock which was the primary interest to the clientThe seismic refraction survey revealed a number of Tertiary buried creek channels interpreted from bedrock depressions Considering the numerous placer deposits occurring within buried channels in the area, these channels are prime exploration targets 1 Two channels occur on line ZO+OOW, one on line 2+5OW, and seven on line 5+00EGEOPHYSICAL REPORT ONA SEISMIC REFRACTION
The shallow refraction seismic survey of Placer Mining Lease No 7073 was carried out on a reconnaissance type survey field work one full day of seismic surveying was accomplished due to the inaccessability of the lease were run The work in the field was slow due to heavy underbrush and soft surface conditionsSince 1990, the Geological Survey of Canada, in collaboration with industry, has undertaken a systematic program to evaluate the use of seismicreflection methods for mineral exploration This endeavour was initiated by Lithoprobe seismicMining Exploration: A New Frontier for the
SEISMIC REFRACTION THEORY Seismic refraction requires the generation of a sound wave into the subsurface of the earth and an instrument to measure the return of the refracted waves The instruments used include a seismograph and spread cable of geophones The seismograph measures the travel times of elastic waves through the subsurface of the earthpact in reducing the cost of the seismic survey In fact, the number of shots can be reduced and the seismic survey optimized to certain depth targets ERT results are also used inElectrical resistivity and seismic refraction tomography
We conducted 2D seismic refraction surveys to delineate the depth to Febearing waste at both sites, assuming that Pwave velocities would increase in Febearing waste compared to the surrounding waste (eg Lanz et al 1998; De Iaco et al 2003) Surveys were conducted along a 115m long transect ARefraction Seismic Exploration'' by Wm Howard Myers , Consultant , November 1977, enclosed in the appendix of the report The field work consisting of a reconnaissance type seismic survey of Placer Mining Lease No 7073 was carried out on August 24th and 25th 1978 A total of one full day was spent carrying out the seismic surveyGEOPHYSICAL REPORT ON SHALLOW REFRACTION

The seismic refraction method had its beginning in the war of 1914–1918, but it became established as a prospecting method in the 1920's and 30's as a result of successes in the Gulf area of the United States The success was an outcome of the parallel development of improved instrumentation and improved methods of interpretationIn mining areas with limited previous seismic acquisition, 2D seismic lines are often acquired to determine viability of the method and optimal survey parameters in advance of a more comprehensive 3D survey Consideration of the design and acquisition strategy can allow additional value to be leveraged from the nominally 2D data At Escondida,Maximising the value of 2D hard rock seismic acquisition
