During the past decade, silver has
been in a pronounced bull market, which many analysts
attribute to its unique attractions as both a monetary
and industrial metal. One Canadian junior miner,
SilverCrest Mines Inc., is working actively to take
advantage of silver’s favorable performance by steadily
expanding production at its flagship Santa Elena Mine
while simultaneously exploring and developing resources
at Santa Elena and its other properties with emphasis on
the company’s new La Joya Property.
I was fortunate to be among a group
of analysts, geologists and journalists invited to take
a first-hand look at the results of SilverCrest’s work
in advancing their projects and preparing for the
future. We were able to visit both Santa Elena, located
in the northern Mexican state of Sonora, and the
developmental La Joya Property, located 45 miles from
Durango City in central Mexico. SilverCrest also owns
the advanced exploration Cruz de Mayo project located
relatively close to Santa Elena.
 |
The company’s highest
priority is continued expansion at Santa Elena,
which achieved its first metals pour in
September 2010 and then commercial production in
mid-2011. Silver and gold production escalated
steadily during latter 2011, and reached 131,045
oz. silver and 9,536 oz. gold for the Fourth
Quarter 2011 and totalled 377,071 oz. silver and
26,969 oz. gold for the year 2011.
Expansion plans at Santa Elena for 2012 - 2014
include construction of a decline to access
underground resources; building a 3,000 to 3,500
tonne per day conventional mill and, by 2014,
combining mill feed from their present open pit
mine with underground resources—all leading to a
planned doubling of production. |
Santa Elena is located some 90 miles
NE of the city of Hermosillo and about a four hour drive
south of Tucson, Arizona and is adjacent to the
community of Banamichi. Hermosillo is a particularly
impressive and vibrant Mexican city and, combined with
Tucson, both cities are fully capable of providing a
wide range of mining supplies and experienced personnel.
Santa Elena is accessible by paved roads and has an
excellent infrastructure with power and adequate water
supplies.
Santa Elena and Cruz de Mayo have seen mining activity
dating back to the late 19th century when initial
production took place. Several underground workings were
opened by early in the 20th Century and four adits were
constructed at Cruz de Mayo. However, active mining soon
ceased upon the onset of the Mexican Revolution of 1912,
with only sporadic interest until SilverCrest entered
the picture in late 2005.
As a result of the company’s exploration work, in
January 2009 they were able to establish Probable
Reserves of 6,541,950 metric tonnes grading 1.61 grams
per tonne (g/t) Au and 56.7 g/t Ag containing 339,600
ounces of gold and 11,927,100 ounces of silver
respectively at Santa Elena. Based on these reserves the
company succeeded in obtaining construction financing,
and they have now entered commercial production using
open pit mining methods. Thanks to increasing production
at Santa Elena, the company was able to announce in
January 2012 that they had been able to retire their
$12.5 million construction loan 21 months ahead of
schedule.
The open pit at Santa Elena is a
particularly impressive site with dual ongoing
operations involving blasting. One area of activity is
designed to strip away waste rock, which is
immediately hauled to a disposal
area,
|
while the other involves active
mining of resources, which are transported directly to
the recovery facilities. While we were visiting, a major
in-pit blasting took place for waste removal and we also
observed additional blasting on a new adit and decline
currently under construction.
SilverCrest has also been able to report underground
Indicated Resources at Santa Elena of 991,100 metric
tonnes grading 1.83 g/t Au and 109.1 g/t Ag, containing
58,330 ounces Au and 3,476,960 ounces Ag plus Inferred
Resources of 1,879,000 tonnes grading 1.53 g/t Au and
86.9 g/t Ag, containing 92,470 ounces Au and 5,250,190
ounces Ag. These underground resources are of particular
future importance considering the company’s plans to
begin mixing underground feed with open pit ore in 2014,
and then gradually transitioning over to feed based on
underground mining operations. In addition, as
production capacity at Santa Elena increases, the
company plans to incorporate ore from Cruz de Mayo as
well as re-processing the treated heap material
resulting from the current open pit heap leach mining
operations at Santa Elena.

Drilling will begin in Second Quarter
2012 to further test and potentially expand the
underground resources at Santa Elena, which remain open
in most directions.
Company reports show Indicated Resources at Cruz de Mayo
of 2,353,400 ounces of silver plus 3,800 ounces of gold
and Inferred Resources of 12,967,100 ounces of silver
plus 20,000 ounces of gold. These resources are near
surface and located only 40 miles from the Santa Elena
mining facilities. A Pre-feasibility Study and
environmental baseline work is currently underway at
Cruz de Mayo for completion by mid-year 2012.
SilverCrest is also working to advance their La Joya
Property where exploration work has indicated
silver-copper-gold mineralization along a strike of
approximately 1.5 miles in length and 300 to 500 meters
in width. Company geologists report mineralization is
occurring along a series of wide (up to fifty meters),
near vertical stockwork veins and structures
crosscutting shallow flat lying skarn deposits up to 30
meters thick.
Prior exploration at La Joya took
place from 1981 through 2006 by Luismin, Bolden and
Solid Resources during which time 56 drill holes
covering 15,720 meters took place.
The company acquired their interest at La Joya in
November 2010, and quickly enlarged their concessions
from 1,625 hectares to a present total of 8,473 hectares
and has the right to ultimately acquire 100% ownership
of the project, subject to a 2% Net Smelter Return (NSR).
The company immediately began exploration programs and,
based on 27 recently drilled core holes and several
verified historical drill holes, a new Resource Estimate
for La Joya was released during January, 2012 which
showed Inferred Resources of 57,940,000 tonnes grading
28 g/t Ag, 0.18 g/t Au and 0.21% Cu, containing 333,400
oz. Au, 51,348,000 oz. Ag and 270,296,000 pounds of Cu
using a cut-off grade of 15 g/t Ag equivalent.
Using a higher cut-off grade of 30 g/t Ag reduces the
Inferred Resource tonnage to an estimated 35.5 million
tonnes with increased grades of 39 g/t Ag, 0.22 g/t Au
and 0.30% Cu. Compared to the lower cut-off grade of 15
g/t Ag Eq., these resources contain approximately 44.3
million ounces Ag, 246,000 ounces Au and 237.5 million
pounds of copper or a total of 86.4 million ounces
silver equivalent.

SilverCrest has completed 17 holes of
a planned 80-hole Phase II drill program, that will
entail an eventual 15,000 meters designed to test the
1.5 miles of the mineralized trend as well as three
adjacent targets with the ultimate goal of establishing
an open pit mining operation.
One of the more interesting prospective areas at La Joya
is known as the Coloradito Target. Six historic holes
were drilled at Coloradito and company COO Eric Fier
noted that, “The Coloradito area shows potential for a
large bulk tonnage Molybdenum, Tungsten, Ag and Au
system with Cu, Lead and Zinc credits. Planned Phase II
drilling during 2012 will further test the extent of
mineralization in the Coloradito area.”
The company’s immediate goal is to double the resource
figures from historic estimates, and a new compliant
Resource Estimate is presently scheduled for early
Fourth Quarter 2012.
Safety at all of its properties is an important concern
for SilverCrest. During a presentation at Santa Elena we
learned that many safety programs had been introduced
including measures such as training new personnel in
safety procedures; enforcement of all international
safety laws and regulations; providing on-site medical
facilities; conducting safety and first aid courses;
inspecting for alcohol and illegal drugs; instruction in
hazardous materials handling; and safety program
follow-ups. |

These procedures appear to be working as the
company recently passed the 500,000 man-hour
mark without any loss of time due to accidents
and/or injuries.
SilverCrest is also conducting extensive
environmental work in order to protect
ecological balance and to minimize any
environmental impact due to their various
operations. In addition, they have filed all
appropriate reclamation reports detailing
procedures that will be put into effect
following termination of mining activities.
A Human Resources department is also maintained
to manage employee relations, comply with
Mexican labor laws and conduct all employee
training. The company also conducts a
high-priority, active program of maintaining
relations with nearby communities. It is also
worth noting that the Santa Elena Mine is a
major employer in the community of Banamichi
with 240 workers including contractors and that
number is expected to increase as future
expansion programs are put into effect.
