Tuffnell Ltd. Announces Drill and Assay Results of Phase II Exploration at the Little Butte Gold/Copper Project in Arizona Which Confirm a Major Shear System With Veins That Contain High-Grade Gold and Copper.
LONDON, March 30, 2011 /PRNewswire/ -- Tuffnell Ltd. (Tuffnell or "the Company") (OTC Bulletin Board: TUFF) is pleased to announce drill and assay results of the Phase II Exploration program at the Little Butte Gold/Copper Project.
Mr. George Dory, Tuffnell's CEO, is pleased to report Tuffnell's drill and assay results. Core drilling confirmed the north-northwest strike and vertical to steeply east-northeast dip of multiple veins. High gold and copper values were confirmed and a possible flat-lying secondary copper blanket identified at the elevation of the paleo-water table.
Drilling consisted of 7 NQ core holes for a total of 1,187 feet. The contractor was Holman Drilling and the rig used was a Longyear 44. Summary results for the 7 holes are shown below

Drill holes LB-1013 and 1014 were drilled to determine the attitude of the vein intersected in LB1010.
Results of 1013 are encouraging in that the entire hole with the exception of the gravel and upper bedrock intersected 86 feet averaging 0.07 oz/ton gold and 0.42% copper. Within this thick intercept is an 8 feet thick vein intercept averaging 24.54 g/t gold and 3.15% copper. Drill hole LB-1014, drilled to intercept the vein 75 feet deeper intersected 50 feet averaging 0.117 oz/ton gold and 0.25% copper.
The results indicate secondary enrichment occurs near-surface for both gold and copper. LB-1019 was drilled to intersect the vein another 100 feet deeper. It found no significant values where the intersection should be although there is a 10 feet zone with no core recovery which might have been a cavity, a likely location for the fault. However, in the upper portion of the hole are two intercepts of potentially ore-grade copper that indicate horizontal migration of copper along a paleo-water table. The lower portion of 1019 cut conglomerates which were found to be unfavorable host rocks in previous drilling.
Drill holes LB-1015 and 1016 were drilled at identical orientations to 1013-1014 100 feet south to intersect the 5 feet thick vein in trench 3. LB-1015 intersected 56.5 feet averaging 0.049 oz/ton gold and 1.00% copper. LB-1016, drilled from the same site but at a 78 degree angle instead of a 45 degree angle intersected nearly 50 feet of shallow mineralization and then a deeper zone of 65 feet of 0.020 oz/ton gold and 457 ppm copper. In a later examination of the drill site it appears that both of these holes were collared in the footwall of the targeted vein and neither hit it.
Drill holes LB-1017 and 1018 targeted the 2.98 oz/ton gold intercept in LB-1009, which was drilled at a 70 degree angle, between 75 and 80 feet. LB-1017 was drilled at 70 degrees and 1018 was drilled at 80 degrees from the same site. The gold results were disappointing. The best gold intercept was 10 feet of 0.055 oz/ton in hole 1018. However, copper intercepts of 40 feet of 0.29% copper in 1017 and 43 feet of 0.33% copper in 1018 make the area worthy of further exploration. Drill hole 1019 was described above.
Trenching and drilling at Little Butte has established the presence of a major shear system and the attitude of specularite-secondary copper veins that contain high-grade gold/copper. The en echelon veins strike north-northwest and dip vertically to steeply east-northeast. High gold/copper values were confirmed and are probably enriched in the upper portions of the veins. A possible flat-lying secondary copper blanket has been identified at the elevation of the paleo-water table, which is above a depth of 150 feet below the current surface. The geophysical survey interpretation indicates the mineralized structures discovered to date are part of a major north-south strike-slip fault system that averages 400 feet in width and is at least 3,000 feet long. Additional north-south structures were identified to both the east and west and a similar but weaker second anomaly occurs along the western margin of the survey. The identification of the geophysical target associated with the mineralization defines a discrete target that can be easily drill tested.
The high-grade vein discovered at Little Butte is one of several high-angle, fault hosted specularite-secondary copper-rich lenses that occur as en echelon structures within a major north-south strike-slip feature. Individual veins have a vertical extent of less than 200 feet with a few hundred feet of strike length. Thickness is less than 20 feet. However, significant gold values are found in a surrounding specularite stockworks zone which can be up to 100 feet thick. Potential ore grade secondary copper also occurs in this stockworks and as a flat-lying zone at the paleo-water table within 150 feet of the surface. With the discovery of several veins and associated stockworks within the 3,000 by 400 feet target currently defined it may be possible to mine the deposit by open pit methods, gravity separate the high-grade gold portion of the veins to recover coarse gold, heap-leach the tails and the stockworks lower grade material for copper and recover it with SXEW and finally heap-leach the same material for gold.
George Dory commented, "Tuffnell's phase 2 exploration program has obviously proven to be a great success. On behalf of the board of Directors I am pleased to share the results with shareholders and the public and look forward to moving ahead with Phase 3".
Tuffnell is in the process of planning its Phase 3 exploration program and believes Phase 3 to be a very important milestone for the company as results continue to be very exciting.
A map showing the location of trenches and the current drilling program as well as photographs during the phase 2 exploration program including those setting out visible gold may be found shortly on the Tuffnell website www.tuffex.com.
The Company also wishes to confirm to the public and its shareholders that as set out in its press release dated March 28, 2011, the Company is pleased to report that its stock is now trading on an Ex Dividend basis meaning that if the stock is now trading at twenty five cents (.25), same is the equivalent of one dollar ($1.00) prior to the Dividend payment.
