Further exploration drilling in the area should focus on identifying the location of any high grade or bonanza grade shoots along the structure. The discovery of such shoots could turn a marginal deposit into a highly profitable one.
VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 11, 2013) – Magellan Minerals Ltd. (TSX VENTURE:MNM) (OTCQX:MAGNF) (“Magellan”) is pleased to report that drill results have been received from six additional diamond drill holes recently completed at the Coringa project located in the southern part of Para state in northern Brazil. Coringa is located in an area of excellent infrastructure and is situated just 20km east of the main BR-163 highway and the Curua – Novo Progresso power line.
These holes are part of the drill program announced in March (see press release dated 12th March 2013) and partially reported on 29th August 2013. They were designed to test certain portions of the resource that were designated as Inferred resources.
- 3m @ 12.58 g/t gold in hole 176 and 2.2m @ 4.91 g/t and 0.5m @ 8.78 g/t gold in hole 178 from the Mae de Leite zone. Hole 176 is the deepest hole drilled so far in the Mae de Leite block and extends the depth of the zone to a vertical depth in excess of 200m. The zone remains open at depth.
- 1.7m @ 12.05 g/t gold from hole 179 at Serra which was drilled in the southern portion of the Serra zone. The zone remains open at depth and to the south
- 2m @ 7.05 g/t gold in hole 174 from the Come Quieto zone representing the best and deepest drill intersection from Come Quieto to date. The zone remains open at depth
The six holes reported here, which total 1,455m, were drilled to a maximum depth of 300m and were largely designed to test the inferred resources at depth and down dip at the Come Quieto, Mae de Leite and Serra zones. All of the holes intersected mineralized vein material.
Of particular note are the results from the Mae de Leite zone which is located 1km WSW of the Serra zone and 2.5km NW of the Meio zone. Hole 176 at Mae de Leite cut 3m @ 12.58 g/t gold approximately 100m below hole 96 which previously intersected 1.3m @ 7.89 g/t gold. Hole 178 similarly intersected 2.2m @ 4.91g/t gold 90m below hole 101 which previously cut 3.6m @ 0.85 g/t gold (see maps and sections on website). These holes have extended the grade and the vertical depth of Mae de Leite to more than 200m, and suggest that the zone remains open at depth.
Hole 179 at Serra was drilled in the southern part of the zone and intersected 1.7m @ 12.05 g/t gold confirming that the Serra zone remains open at depth to the south (see long section on website). The strike length of the Serra structure is now 1.35km in length. The most southerly hole at Serra which was drilled as part of this program (see press release dated 29th August 2013), was hole 161 which cut 1.5m @ 3.09 g/t gold including 0.5m @ 8.03 g/t gold.
Hole 174 at Come Quieto intersected 8m @ 2.05 g/t gold including 2m @ 7.05 g/t gold. The hole is the best hole drilled to date at Come Quieto and was drilled at the southern edge of the zone approximately 50m south and 40m down dip of hole 122 which previously cut 3m @ 5.1g/t gold and 20m north of hole 120 which intersected the mineralized structure but returned only low gold values including 0.6m @ 1.52g/t gold and 0.6m @ 0.97g/t gold (see map on website). The mineralized zone at Come Quieto remains open at depth.
The complete summary of significant intersections is as follows:-
|Hole ID||From (m||)||To (m||)||Interval Width (m)*||Gold (g/t||)|
|Mae de Leite|
|1||All holes were drilled at between -55° and -75°. Dips of the intersected structure at Come Quieto, Mae de Leite and Serra are not known, and intersection widths are not necessarily true widths|
|2||True widths at Serra and Mae de Leite are estimated at 75-95% of the drill intersections|
|3||True widths at Come Quieto are estimated at 60-80% of the drill intersections.|
|4||Holes 169-173 were condemnation holes specifically designed to test the proposed sites for the plant and tailings disposal. None of the four holes intersected significant mineralization.|
Commenting on the results of the 2013 infill drill program at Coringa, Alan Carter, President and CEO commented “the recent drill program at Coringa was designed to test the boundaries of the known mineralization at the Serra, Mae de Leite and Come Quieto zones and extended the mineralization in several directions particularly to depth in all three zones. This round of drilling has built on our previous work which demonstrates that Coringa is one of the largest, high grade undeveloped gold deposits in Brazil”.
Holes were drilled at between 55 and 75 degrees from horizontal. All core samples (NQ diameter) were cut with a diamond saw and one-half of the core placed in bags, numbered and sealed then sent via a secure transport agency to the Company’s office in Itaituba before shipping via secure transport to ACME preparation laboratory in Itaituba for sample preparation. Core samples were crushed down to 2 mm and a 1 kg split was pulverized to better than 85% minus 200 mesh. From Itaituba, ACME sent the pulp samples to Santiago, Chile for assaying. Gold analyses were conducted on 30g representative sample cuts using fire assay with an atomic absorption finish. ACME is an ISO 9001 registered laboratory and has a quality control program in place which includes the insertion of standard, blank, and duplicate samples, as well as conducting repeat analyses.
Magellan’s QA/QC program also includes the insertion of standards, field duplicates and blank material in the sample sequence with the normal core samples to monitor sampling variances, laboratory precision and accuracy.
