Magellan Minerals Ltd.: Drilling at Serra Intersects 4m @ 7.16 g/t Gold Coringa Project, Brazil
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/17/11 -- Magellan Minerals Ltd. (TSX VENTURE: MNM) ('Magellan') is pleased to report results from nine additional drill holes from the Serra, Come Quieto, Valdette, and Meio zones at the Coringa project, Brazil. These holes are all step-out and exploration holes aimed at expanding the existing resources of 269,450oz of gold in the measured and indicated categories (982,291t @ 8.53 g/t), and 98,224oz of gold in the inferred category (327,054t @ 9.34 g/t).
Highlights include:
-- 4m @ 7.16 g/t gold including 1m @ 16.34 g/t gold in hole 132 at Serra
drilled 100m north of hole 121 and 100m below previous holes;
-- 0.5m @ 12.1 g/t gold in hole 135 drilled 70m north of hole 121 at the
northern limit of Serra;
-- 3m @ 5.10 g/t gold in hole 122 at Come Quieto suggesting the presence of
another mineralized zone along the main structure at Coringa; and
-- 8m @ 2.06 g/t including 4m @ 3.55 g/t gold and 0.5m @ 10.10 g/t gold in
hole 126 also drilled at Come Quieto 100m NW of hole 122. The area
extending 600m NW from hole 126 has never been previously drill tested.
Serra
Results are reported here on two additional holes drilled down dip on the existing structure. Hole 132 was drilled 100m south of hole 121 and 100m down dip of previous drilling and intersected 0.5m @ 4.4 g/t gold from 117.0 to 117.5m depth and 4m @ 7.16 g/t gold from 136.4 to 140.4m depth including 2m @ 5.99 g/t gold and 1m @ 16.34 g/t gold (see map and longitudinal section on website). Hole 121 previously intersected 1m @ 118.27 g/t gold (see September 13th, 2011 news release).
Hole 135 was drilled on the northern limit of the Serra zone and returned 1.1m @ 2.78 g/t and 0.5m @ 12.1 g/t gold). Hole 135 was drilled 70m north and 40m down dip of hole 121 and expands the strike length of the Serra zone to the north by a minimum of 70m.
The Serra zone has an existing resource of 161,731oz of Measured and Indicated resources (Measured; 210,405t @ 8.59 g/t gold and Indicated; 336,004t @ 9.59 g/t gold) and 94,294oz of Inferred resources (280,794t @ 10.44 g/t gold). These results continue to expand the mineralized zone at depth and along strike. Results are currently pending on an additional four deep holes at Serra.
Analytical results from the Come Quieto, Serra and Valdette zones discussed in the text are tabulated below.

(i) All holes were drilled at between -50 degrees and -65 degrees. Dips
of the intersected structures at Come Quieto and Valdette are not
known, and intersection widths are not necessarily true widths.
(ii) True widths at Serra are estimated at 60-95% of the drill
intersections.
(iii) Results are pending on holes 129, 130 and 134.
Come Quieto
Results were returned from two holes (122 and 126) at the Come Quieto target which is located approximately 1.7km SE of the Meio zone and is not part of the existing resource at Coringa. Hole 122 was drilled approximately 100m NW of hole 120 and intersected 1m @ 4.90 g/t gold from 51.0 to 52.0m depth and 3m @ 5.10 g/t gold from 133.0 to 136.0m depth (see map on website).
Hole 126 was drilled 100m NW of hole 122 and intersected 8m @ 2.06 g/t gold from 127.0 to 135.0m depth including 4m @ 3.55 g/t gold from 129.0 to 133.0m and 0.5m @ 10.10 g/t gold from 185.0 to 185.5m depth.
The zone to the north of hole 126 remains open for a strike length of at least 600m raising the possibility of a new mineralized zone along the main structure at Coringa. This part of the structure has a number of old workings but never been previously drill tested and will require further drilling.
Valdette
Results were returned on three additional holes drilled on the Valdette structure. Hole 128 intersected 7m @ 0.87 g/t gold (see map on website) and was drilled 140 m south of hole 110 which intersected 1m @ 2.38 g/t, 2m @ 1.43 g/t and 1m @ 2.80 g/t gold (see July 12th, 2011 news release). Hole 128 marks the southern-most hole drilled at Valdette and extends the mineralized zone a further 140m to the south.
Hole 131 was drilled on the northern limit of Valdette 170m north of hole 119 and intersected 5m @ 0.86 g/t gold. Hole 133 was drilled between holes 119 and 131 and cut 1m @ 1.14 g/t, 1m @ 2.35 g/t and 0.5m @ 1.77 g/t gold.
These results from Valdette confirm the presence of a mineralized structure of at least 1000m in length which remains open both to the north and south and at depth.
Drilling is currently in progress on the down dip extensions to the Meio and Serra structures which contain the bulk of the resource at Coringa and at the recently discovered Domingo structure.
All core samples (HQ diameter) were cut with a diamond saw. One-half of the core was placed in numbered and sealed bags and sent via a secure transport agency to the Company's office in Novo Progresso, and subsequently 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. Other sample cuts were subjected to a 4 acid digestion and analysed for silver and an additional 35 elements using inductively coupled plasma mass spectrometry (ICP-MS). 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 includes the insertion of standards, field duplicates and blank material into the sample sequence with the normal core samples to monitor sampling variances, laboratory precision and accuracy.
