Avanti Intersects 395.1 Meters Averaging 0.088% Molybdenum at Kitsault

VANCOUVER, Aug 25, 2011 - Avanti Mining Inc. (TSX-V: AVT) (PINKSHEETS: AVNMF) (“Avanti“ or the “Company“) is pleased to announce that it has received assays from the next 10 holes of its 2011 drill program at the Kitsault Mine molybdenum project located in northwest British Colombia. Four of these holes were drilled into the northwest portion of the Kitsault mine project where previous drilling had not completely defined the extent and quality of mineralization and six are from the Roundy Creek prospect located approximately 4 km west of the Kitsault mine.


Drill highlights include:

- Hole K11-13 intersected 395.1 meters averaging 0.088% molybdenum and 3.8 g/t silver while bottoming in mineralization -- one of the best holes drilled at Kitsault and extended the zone to the north and depth.

- Hole K11-14 intersected 122.3 meters averaging 0.081% molybdenum and 3.5 g/t Ag while bottoming in mineralization

- Hole RC11-01 intersected 76.2 meters averaging 0.095% molybdenum and 1.1 g/t silver while bottoming in mineralization

- Hole RC11-02 intersected 98.9 meters averaging 0.175% molybdenum and 1.7 g/t silver while bottoming in mineralization

- Hole RC11-03 intersected 138.2 meters averaging 0.144% molybdenum and 2.9 g/t silver while bottoming in mineralization

- Hole RC11-04 intersected 111.2 meters averaging 0.058% molybdenum and 2.2 g/t silver while bottoming in mineralization

- Hole RC11-05B intersected 120.4 meters averaging 0.058% molybdenum and 4.5 g/t silver while bottoming in mineralization

- Hole RC11-06 intersected 150.9 meters averaging 0.130% molybdenum and 1.8 g/t silver while bottoming in mineralization

“Drilling at the Kitsault Mine molybdenum project and Roundy Creek prospect continues to highlight the robust nature of mineralization on our property,“ said Craig J. Nelsen, President & CEO of Avanti. “While many of the drill holes have bottomed in mineralization, at Kitsault this is because we are at the bottom of the resourse shell and at Roundy Creek, we are trying to confirm the high grade within 100 meters of the surface. The Roundy Creek geologic model is being developed at this point in time and most of the drilling reported here is in the eastern part of the Sunshine Creek project where very little previous work has been completed.“

1. Principal composites are calculated at a cut-off grade of 0.027% molybdenum as stated in the 2010 Feasibility Study and allow inclusion of up to nine meters of material below that grade. Other cut-offs (internal to the main 0.027% zones) at 0.05% and 0.10% molybdenum use the same compositing rules. Multiple intersections in a hole are separated by the word “and“. As Roundy Creek is intended to be a high-grade satellite feed, cut-offs at 0.05% or 0.10% molybdenum are more appropriate.

2. Gaps in the Kitsault hole number sequence indicate drilling conducted elsewhere on the property for condemnation purposes that do not contain significant mineralization.

3. Approximate horizontal widths at Kitsault can be calculated by multiplying the drill thickness of a -45 degree inclined hole times 0.7 and a -60 degree inclined hole by 0.5. Roundy Creek horizontal widths are unknown at this point as the geologic model is being developed.

4. Silver results on the above table are included for informational purposes only. Please consult the Company's recent Kitsault Mine Feasibility Study for a discussion on the possibility of silver by-product recovery. No revenues have been assumed for silver in the Kitsault Feasibility Study but metallurgical test that may develop a saleable silver by-product are underway.


All of the sawn half core drill samples (dominantly HQ size) collected by Company personnel are delivered to the ALS Minerals sample preparation lab in Terrace, B.C. where they are logged into the computer tracking system, crushed, split and a pulp sample prepared. Various quality control tests for crushing and labeling accuracy are performed at this lab. The pulp samples are then sent to the ALS Minerals laboratory in Vancouver, B.C. for 33-element analysis by Inductively Couple Plasma - Atomic Emission Spectroscopy. ALS Minerals is an ISO/17025 certified laboratory. ALS monitors quality control through the introduction of blanks, standards and duplicate sampling. In addition, Avanti personnel routinely insert hidden blanks and standards into the sampling stream. Bruce Davis, AUSIMM, is responsible for analyzing the QA/QC aspects of this work and Ken Collison, P. Eng., Senior Vice President Project Development, is responsible for the technical information in this press release. Both individuals are Qualified Persons as defined by NI 43-101.


Avanti Mining Inc. is focused on the development of the past producing Kitsault molybdenum mine located north of Prince Rupert in British Columbia. In late 2010, Avanti completed the Kitsault Feasibility Study on the Kitsault Mine Project, dated December 15, 2010, prepared by AMEC Americas Limited that showed Proven and Probable Reserves of 232.5 million tonnes averaging 0.081% molybdenum.
