Trading Symbols: GTP - (TSX-V) P01 - (FRANKFURT) COLTF - (OTCQX)
MONTREAL, April 30 /PRNewswire/ - Colt Resources Inc. ("Colt" or the "Company") (TSXV: GTP) (FRA: P01) (OTCQX: COLTF) is pleased to announce that it has received final analytical results corresponding to three recently completed drillholes from the ongoing drilling and trenching campaign on its Boa Fé gold project, located within the Company's 100% owned (47Km2) Boa Fé Experimental Mining License ("EML") in southern Portugal. The Boa Fé EML is completely surrounded by the Company's 100% owned (732Km2) Montemor exploration concession.
The results from the Chaminé and Ligeiro deposits are highlighted as follows:
------------------------------------------------------------------------- Chaminé Deposit ------------------------------------------------------------------------- Drill hole BFCH-12-021 (Vertical) - 40.50m long ------------------------------------------------------------------------- From (m) To (m) Grade g/t Au Interval (m)* ------------------------------------------------------------------------- 6.70 21.15 6.96 14.45 ------------------------------------------------------------------------- (Including) 6.70 12.25 16.96 5.55 ------------------------------------------------------------------------- and 17.15 21.15 2.03 4.00 ------------------------------------------------------------------------- Drill hole BFCH-12-023 (Vertical) - 80.50m long ------------------------------------------------------------------------- From (m) To (m) Grade g/t Au Interval (m)* ------------------------------------------------------------------------- 13.70 37.28 5.42 23.58 ------------------------------------------------------------------------- (Including) 29.70 37.28 11.60 7.58 ------------------------------------------------------------------------- Ligeiro Deposit ------------------------------------------------------------------------- Drill hole BFLG-12-005 (Vertical) - 64.90m long ------------------------------------------------------------------------- No significant results ------------------------------------------------------------------------- * True Width has not been determined at this time.
Nikolas Perrault, President and CEO of Colt, stated, "We continue to be impressed by the results from this well mineralized shear zone. Our mine development team is working hard to test the known deposits while our exploration team is ramping up regional exploration using a variety of techniques including drilling trenching and geophysics. We remain committed to demonstrating that this area has the potential to host a very significant gold mineralized system."
Program Strategy
Gold mineralization has been identified in several deposits along a shear zone that extends over some 30 Kilometers along strike (Figure 1). Previous shallow drilling (Figure 2) was focussed on the highest grading portions of gold anomalies that closely follow the regional shear. The mineralisation style interpreted in the current model assumes that high-grade gold mineralisation occurs where conjugate sets of shears intersect and reinforce each other (refer to press release 15th March 2012).
Hole BFCH-12-021 was drilled vertically on section 6350N to test structural continuity of the model and complete infill drilling on this section line (Figure 3). Results from this hole confirm the presence of high-grade mineralisation near surface where a set of shears dipping westward intersect a horizontal 'saddleback' type structure.
Hole BFCH-12-023 is a vertical hole located 25m north of hole BFCH-12-021 and drilled to confirm continuity of mineralisation along strike. Consistent high-grade mineralisation occurs over extended intercept widths and again confirms the continuity of the structural interpretation northward.
Hole BFLG-12-005 is a vertical step out hole that was drilled to the west of the Ligeiro mineralized zone to test for the presence of near surface mineralization in an area that had not been previously tested. Low grade gold mineralization was intersected but no significant assay results were reported.
Results from trenching in the Chaminé-Ligeiro gap (BFLGT-12-004 through to BFLGT-12-008) show anomalous gold values. These results along with other multi-element analyses will be checked against previous trenching results to investigate whether other metals show secondary anomalies which can be used as pathfinders for buried mineralization where gold and arsenic anomalies have not been detected at surface.
Colt has now completed a first pass structural interpretation of the entire Chaminé deposit on plan and cross-sections that incorporate the concept of conjugate shear orientations reinforcing each other and leading to higher grades of gold mineralization. This work will now be further streamlined and built into a robust 3D model.
The Company will continue its aggressive advanced stage exploration campaign at Boa Fé consisting of a combination of vertical and inclined drill holes positioned to confirm previous drilling results at the Chaminé, Casas Novas, Braços, Banhos and Covas deposits and investigate the gaps between Chaminé-Casas Novas and Chaminé-Ligeiro to increase resource potential. Results currently being interpreted from geophysical exploration (resistivity and seismic orientation surveys across Chaminé) will greatly assist in advancing targets in the gap areas. High priority regional targets identified through historical data assessment and field prospecting will also be tested. The results of this phase of work will form the basis for an initial NI 43-101 compliant resource estimate to be prepared later in 2012 covering several previously drilled gold bearing deposits within the Boa Fé EML.
Minimal drilling has been performed to test depth extensions below an average of 100 metres or along strike between known mineralized deposits. Given the shear zone style of mineralization and extensive gold anomalies in soils, there is good potential to build upon previous work that supported several non NI43-101 compliant resource estimates (see press release March 7, 2011).
Quality Assurance / Quality Control (QA/QC)
Drill sample intervals are reported as metres (m) down hole and as such do not represent true widths of mineralized intersections. All drill core is transported by the Company personnel from drill site to a nearby secure storage facility for logging and sampling. Sampling intervals are defined after core logging and determination of probable high grade zones based on visible mineralisation and favourable structure. The core is halved using a rotary diamond blade core saw, with one half of the core sent for analysis, while the other half is retained in the core boxes for future reference.
All half core samples are sent by courier to ALS Chemex's facility in Seville, Spain, where they undergo sample preparation. The resulting pulps are shipped by ALS to their laboratory in Romania for gold assay and routine ICP multi-element analysis. Gold analysis for all samples is done via method "Au - AA23" (Au by fire assay and AAS, 30g nominal sample weight). The detection limit for this method is 5 ppb. For every sample with Au values over 3 ppm, the pulp is re-analyzed by method "Au - GRA21" (Au by fire assay and gravimetric finish, 30g nominal sample weight). The detection range for this method is 0.05-1000 ppm.
A set of standards and blanks has been inserted by Colt into the drill sample stream on a regular basis in addition to the laboratory's own internal QA/QC standards and duplicates. QA/QC results to date are well within the accepted norm.
