![]() The soils here are conducive to using a directional drill and I will be able to schedule the work better and hopefully control costs and cleanup. I am unwilling to spend two years as an apprentice driller (not that anyone would hire a worn-out HVAC business owner) just to become licensed to drill a vertical hole and thought about using a directional horizontal rig. My problem is three-fold 1) The geo drillers prices have shot up in my area, 2) None have been very reliable, 3) The rigs and crews leave a big mess for us to clean up after. I'm hoping another geo professional or informed homeowner will be able to give me some insight on their experience/success/problems/performance concerning using a directional horizontal boring rig to install the HX field. The program will be staged and conducted over a 12 to 24 month period.Long time lurker, first time poster. This may vary depending the pricing and supply of drilling consumables. Proposed at an all up cost of approximately $AUD 120 per metre for 12,500 metre of RC drilling and $200 per metre for 2,250 metres of diamond drilling, it is anticipated that the drilling program will cost up to approximately $AUD 2,000,000 to complete. The estimated cost to conduct the surface sampling program is $AUD500,000. A number of RC or diamond drill holes are required to test the airborne and subsequent ground EM targets identified in association with surface gold at the target areas.To test a number and variety of quality gold in soil anomalies specific target areas.A 10 hole combined RC and diamond drill program in 2011 to test the continuity and extent of gold mineralization intersected during 2008 at the Wealth of Nations Prospect.Prospecting and mapping over the newly granted tenements.A total of 5,000 soil and rock samples collected across the property.Depending on where you are in the world this may also be calculated as the average cost per metre drilled.Ĭomparative cost of Exploration Program and Budget for a standard project in 2011įollow-up exploration will be staged and conducted over a 12 to 24 month period and should include but not be limited to: This value is used for evaluating drilling projects, bit performance, drilling performance, etc. Average Cost Per Foot Drilledĭrilling cost per foot is the total drilling cost per footage drilled. RC Drilling offers this flexibility which makes it the most cost and time effectiveĭrilling method. One option is using a multipurpose rig doing both techniques consecutively on the same hole or if initial assay results from RC Drilling are promising and deeper samples are required returning to use the initial RC hole and commence diamond coring to greater depths. RC drilling can also used as a precollar to diamond drilling and there are two ways of doing this. There are also significant cost and time reductions in the overall RC sampling process. ![]() ![]() Diamond drilling consumables are also more expensive as they are custom made to suit the rig. However RAB drilling gives a less accurate sample and is primarily used in initial exploration in unconsolidated ground limited to depths of approximately 100m. Because it is less complex, time consuming and has faster penetration rates RC drilling (Reverse Circulation) is usually 25 – 40% cheaper than diamond drilling, although RC is more expensive then RAB (Rotary Air Blast).
