Hecla Receives Final Board Approval on Lucky Friday #4 Shaft and Provides Update on Pre-Development Projects

08.08.2011  |  Business Wire


Hecla Mining Company ('Hecla?)(NYSE:HL)
announced today that its Board of Directors has approved the completion
of the #4 Shaft Project at the Lucky Friday mine. Hecla is also pleased
to report progress on its Star (Silver Valley ? Idaho), Equity/Bulldog
(San Juan Silver JV ? Colorado) and Hugh Zone (San Sebastian ? Mexico)
pre-development projects and exploration efforts.

HIGHLIGHTS


  • The Lucky Friday #4 Shaft Project received final Board of Directors′
    approval

  • Exploratory drilling at Lucky Friday identified high-grade
    mineralization in the Silver Fault and intense alteration to the west

  • Rehabilitation of the Star drift has been initiated and work is in
    progress to re-establish power and ventilation

  • Equity mine portal and ventilation adit successfully re-opened and
    preparations are under way for underground drilling

  • Underground drilling at Greens Creek continues to refine and extend
    mineralization at the south perimeter of the Gallagher zone

  • A scoping study has been initiated to re-evaluate the Hugh Zone and
    integrate this with a study on the nearby Andrea Vein


'Hecla is now positioned to significantly grow production over the next
five years,? said Hecla′s President and Chief Executive Officer,
Phillips S. Baker, Jr. 'With approval of the #4 Shaft Project,
developments at the Greens Creek mine and the scoping studies in the
Silver Valley, San Juan Silver, and San Sebastian properties, we have a
goal of 15 million ounces of annual silver production by 2016. We
believe our strong financial position combined with cash flow generation
from Greens Creek and Lucky Friday would be sufficient to cover our
settlement obligations, sustaining and capital expenditures,
pre-development projects, and exploration programs.?


The production growth initiatives include three categories:
construction, scoping studies, and exploration. Construction for
production growth is primarily the #4 Shaft Project at the Lucky Friday.
Scoping studies are under way for the Star, Bulldog and Hugh Zone to
potentially re-open those mines, for the Lucky Friday optimization, and
for Greens Creek′s East Ore Zone.


Exploration expenditures during the second quarter were slightly lower
than expected at $5.8 million due to heavy snowfall and cool spring
temperatures which delayed the start of the drilling programs. During
the quarter a number of drill programs occurred in Mexico, the Silver
Valley, Greens Creek, Lucky Friday and the San Juan Silver JV. The
majority of the exploration expenditures during the second quarter
included Greens Creek with $1.94 million, San Juan Silver JV with $1.36
million, San Sebastian in Mexico with $1.23 million, and Lucky
Friday/Silver Valley with $0.82 million. The exploration budget for 2011
was increased from $27 million to $32  million due to the establishment
of pre-development initiatives and the expansion of exploration
programs, primarily in Mexico. In addition, capital expenditures for
2011 have increased from $100 million to $115 million primarily from the
acceleration of projects at Greens Creek.

LUCKY FRIDAY & SILVER VALLEY ? IDAHO

#4 Shaft Project - Construction


The #4 Shaft Project at Lucky Friday progressed well during the second
quarter. The detailed engineering for an internal shaft descending from
the 4900 level to 8800 level was completed and final Board of Directors′
approval for completion of the project was received.


'We are very pleased with the progress of the #4 Shaft Project at the
Lucky Friday,? said Hecla′s President and Chief Executive Officer,
Phillips S. Baker, Jr. 'The addition of the new shaft is expected to
extend the mine life by more than 20 years and increase production by an
additional two million ounces of silver per year with higher grades and
mill throughput. We expect the Lucky Friday, which started in 1942, to
be one of the few world-class assets to operate for more than a century.?


Total capital expenditures for the #4 Shaft Project in the second
quarter and first half of 2011 were $10.8 million and $22.4 million,
respectively, for a total of approximately $70 million invested to date
on the project. Total project capital is expected to be approximately
$200  million, which includes $45 million budgeted for the full year of
2011, $40 million in both 2012 and 2013, and the remaining balance in
2014. We anticipate project completion in the second half of 2014.


Included below are key forecasted production metrics for the Lucky
Friday mine once the #4 Shaft comes into production (production ramp-up
from 2014-2016):

  1. This Mine Life/Mine Rate does not include additional potential

The hoist room and associated equipment installation were completed in
the first half of 2011. We expect to start sinking shaft in the fourth
quarter of 2011. The total project is now 38% complete and 78% of major
procurements have been ordered or installed.


The economics of the #4 Shaft Project was limited by the capacity of the
mill; hence, Hecla initiated a mine optimization study to understand the
limits of the mine infrastructure. We expect this study to increase
silver production beyond 5 million ounces annually. The study is
expected by year-end.

Star ? Pre-Development Project


In North Idaho′s Silver Valley, the Star-Morning mine operated from 1891
to 1982 and in the early 1990s. The Star-Morning mine was the second
largest producing mine by tonnage in the Coeur d′Alene Mining District,
reporting historic production of 71.6 million ounces of silver, 1.7
million tons of lead and 1.6 million tons of zinc (25.9 million tons at
2.7 ounces per ton silver, 6.6% lead, and 6.3% zinc). The Company has
initiated a re-opening study.


Crews are currently rehabilitating the infrastructure and
re-establishing ventilation on the Star 2000 level. Once access is
re-established, drilling will begin to evaluate extensions of
past-producing vein systems (Star, Noonday, You Like and Lucretia) in
proximity to historic mine infrastructure. The current understanding of
the vein structures suggests potential to define in excess of 30 million
ounces of silver with significant zinc and lead above the water table.
This rehabilitation work is expected to be complete by year-end and
drill platforms established shortly afterward.


While the Star drift will provide access for exploration and potential
production above the water table, further dewatering and refurbishment
of the historical Star production shaft could allow access to deeper
resources that were formerly classified as reserves when the mine closed
in 1982. Additional development could create a common connection to the
existing underground development at the Lucky Friday mine for
ventilation and exploration.

Exploration


At Lucky Friday the definition and exploration drilling program is
focusing in four key areas and recent assay results are shown in
Appendix A:


  • Drilling from the 4050 level at the top of recent mine workings
    evaluated veins to the east between the 3600 level and 4100 level.
    This drilling has defined new resources in the 30 and 40 veins and
    suggests that mineralization is still open to the east and above the
    current resource.
  • Definition drilling continues to refine and upgrade the
    resources along the 20, 30 and 50 veins from the 6200 level to 6800
    level
    to the west up to the Silver Fault.

  • Exploration drilling continued from the 5900 level #4 Shaft station
    and identified strong mineralization in the 30, 40 and 90 veins at the
    west side of the deposit to about the 6700 level to 7200 level.

  • An exploration hole from this station drilled westward was able to
    encounter and then cross the Silver Fault at approximately the 7800
    level
    . Two wide, high-grade vein intercepts were identified in the
    Silver Fault.


In the Silver Valley, surface drilling has been under way since June at
the Star on the  You Like and Lucretia targets resulting in a  high-grade
1.4 foot wide intersection of 48.4  ounces per ton silver, 3.4% lead, and
0.3% zinc, and 1.0 foot wide intersection of 13.3  ounces per ton silver,
15.3% lead, and 8.9% zinc. The first hole of an extensive drill program
to expand the Noonday resource intersected an 18.3 foot wide interval of
13.0 ounces per ton silver and 22.2% lead.

SAN JUAN SILVER JV ? COLORADO

Equity Mine ? Pre-development Project


In the second quarter, Hecla successfully re-opened the Equity (North
Amethyst) portal and ventilation adit at the San Juan Silver JV property
in Creede, Colorado. The portal re-opening will provide additional
underground drill platforms to evaluate the recent discovery of
gold-silver mineralization from last year′s surface drilling and to
provide better definition of the high-grade ore shoots previously
investigated in the 1980s. The underground drill program is being
designed and could start to test targets at the Equity and West Amethyst
veins by year-end. Underground access will allow for year-round
exploration activities instead of seasonal work on these structures.

Bulldog Mine ? Pre-development Project


A major piece of the San Juan Silver JV land package includes the
historic Bulldog mine, which produced 25 million ounces of silver for
Homestake Mining before closing in 1985 as a result of lower metals
prices. Hecla is developing a program to allow the construction of the
surface infrastructure necessary to re-open the Bulldog mine to confirm
and expand resources, and access the ore zones.

Exploration


Two drills have been operating on surface in Creede, Colorado since
mid-May and have focused on extending mineralization along the Bulldog,
Amethyst, Equity, and OH veins. This year′s first drill hole targeted
the northern trend of the 'A Vein? on the Bulldog Vein system and
intersected a 15-foot vein that contains galena, sphalerite,
chalcopyrite, and fine-grained silver sulfosalts. Drilling has shifted
to the east to drill the northwest extension of the OH Vein, a
high-grade, past producer where the first hole has encountered a 4.5
foot wide barite-quartz vein and a 5.0 foot wide pyrite-barite-quartz
vein in the hanging wall of the main OH Vein.


The first drill hole this year to follow up on last year′s successful
Amethyst Vein drilling encountered the west strand of the Amethyst Vein
grading 0.2 ounce per ton gold, 6.0 ounces per ton silver, 1.6% copper,
0.9% lead, and 4.1% zinc over 1.8 feet. This intercept is about 10,000
feet on strike to the south from where the Equity mine is developed on
the Amethyst Vein.


The Equity drilling targeted the newly interpreted location of the west
strand of the Amethyst Vein structure. The upper sections of the hole
have encountered mineralized structures and veinlets.

SAN SEBASTIAN ? MEXICO

Hugh Zone & Andrea Vein ? Pre-development Project & Exploration


The Hugh Zone is a high-grade down dip extension of the past-producing
Francine Vein. A scoping study has been initiated to re-evaluate the
previous Hugh Zone scoping work and integrate this with a study on the
nearby Andrea Vein. The Hugh Zone currently contains an Inferred
Resource of 1,142,500 tons grading 8.0 ounces per ton silver, 0.01 ounce
per ton gold, 2.9% lead, 4.4% zinc, and 2.1% copper.


In the second quarter, exploration drilling continued to extend the
Andrea Vein to the southeast. Although the Andrea Vein has been defined
over 1.7 km of length, there are two higher-grade sections which total
1.2 km in strike length that are separated by a lower-grade segment of
the Andrea Vein.


Initial 3D and economic modeling indicates the remnant Don Sergio
mineralization and the newly intersected Andrea Vein may represent an
economically viable target due to their close proximity. Since the
mineralized vein is still open along strike, the in-fill drill programs
on the Andrea Vein will focus on the definition of known higher-grade
areas.

GREENS CREEK ? ALASKA

East Ore Zone


At Greens Creek, Hecla has retained a contractor to engineer the planned
re-access into the East Ore Zone for the development of a mine plan that
will extend Greens Creek′s mine life. Currently, reserves in the East
Ore Zone are 683,000 tons at 13 ounces per ton silver and 7.89% zinc.
East Ore Zone resources consist of 1.2 million tons at 12.6 ounces per
ton silver and 7.14% zinc. Exploration potential remains along strike to
the southeast.

Exploration


Definition and exploration drilling of the western and southern
extensions of the Gallagher zone defined a shallow, west dipping baritic
ore zone containing lenses of massive sulfides and white carbonate
material that vary from 15 to 45 feet in thickness and contain narrower,
high-grade intervals. The mineralization outlined by this drilling
measures approximately 120-feet along strike and 400 feet down dip.
Assay results from the second quarter of 2011 with intersections of the
Gallagher zone are shown in Appendix B.


Two drills will move next month to the 1147 Drift to initiate
exploration drilling of the 200 South ore trend where over 22 million
ounces of silver and 150,000 ounces of gold were added to resources in
2010. Designs for underground development are under way to provide drill
platforms for in-fill drilling.


Three surface drills are on-site at Greens Creek until late September.
Drilling has intersected the mineralized Lower West Wall target which is
offset by the Maki Fault at the north end of the mine. Another drill is
targeting the eastern extension of the East Ore Zone and the underlying
Northeast contact that extends through this area. About two miles north
of the current mine workings in the Cub area, drilling has intersected
two and three-foot wide mineralized intervals in the shallow projection
of the Northeast contact.
