Titan Mining Updates Reporting at Mineral Ridge
26 Fevereiro 2021 - 5:50PM
Titan Mining Corporation (TSX: TI) (“
Titan” or the
“
Company”) announces that in satisfying the
reporting requirements of the British Columbia Securities
Commission Titan commissioned an independent consultant to prepare
a technical report on the Mineral Ridge Project.
The technical report for Titan was based on a
technical report with an effective date of January 2, 2018,
summarizing a feasibility study that was prepared for Scorpio Gold
Corporation (“Scorpio Gold”) on Mineral Ridge. The
technical report prepared for Titan differs in some respects to
that prepared for Scorpio Gold given the more recent effective date
of the report of December 1, 2020, and includes the
reclassification of the Measured Mineral Resources within the
existing heap leach pad to Indicated Mineral Resources, an addition
of a surge pile to accommodate the crusher which modified the
capital cost estimate, changes to the power costs that modified the
operating cost estimate, review of commodity prices, and review of
inputs to the economic analysis including changes to the gold price
used in the analysis.
The results of the study indicated that
approximately 14,000 ounces of gold had been recovered from
continued leaching from the existing leach pad since the 2018
technical report. While the independent consultant has confirmed
that the volume of material on the leach pad is generally unchanged
(outside of the 14,000 ounces of gold recovered from continued
leaching), the extraction has made it unclear where the reported
Measured Mineral Resources estimated for Scorpio Gold are precisely
located on the leach pad. As a result, the independent consultant
revised the Measured classification to Indicated. The below updated
estimate of Mineral Resources and Mineral Reserves reflects the
foregoing revisions.

Notes:
-
The effective date of the Mineral Resource estimate is December 1,
2020. The QP for the estimate is Mr. Ian Crundwell, P.Geo.
-
Mineral Resources are quoted inclusive of Mineral Reserves. Mineral
Resources that are not Mineral Reserves do not have demonstrated
economic viability.
-
Mineral Resources are contained within the Mineral Ridge leach pad
facility with the following assumptions: a long-term gold price of
$1,216/oz; assumed process costs of $11/t; and metallurgical
recovery for gold of 91%.
-
Silver was not used in the consideration of reasonable prospects
for eventual economic extraction. Silver recoveries from heap leach
pad material are projected to be 24%.
-
Rounding may result in apparent differences when summing tons,
grade and contained metal content. Tonnage and grade measurements
are in Imperial units. Grades are reported in ounces per ton.

Notes:
- The effective date of the Mineral Resource estimate is December
1, 2020. The QP for the estimate is Mr. Ian Crundwell, P.Geo.
- Mineral Resources are reported inclusive of Mineral Reserves at
a gold cut-off grade of 0.01 opt. Mineral Resources that are not
Mineral Reserves do not have demonstrated economic viability.
- Mineral Resources are constrained to the area within the
grade-shell wireframes. The areas outside of these grade shells are
assumed to be at zero grade.
- These Mineral Resource are considered to be amenable to
open-pit mining. Conceptual Whittle pit shells used the following
assumptions: a long-term gold price of $1,350/oz; assumed combined
operating costs of $12.36/t (mining, process, general and
administrative); metallurgical recovery for gold of 95%, and
variable pit slope angles that ranged from 38–42º.
- Rounding may result in apparent differences between when
summing tons, grade and contained metal content. Tonnage and grade
measurements are in Imperial units. Grades are reported in ounces
per ton.

-
Mineral Reserves are contained within the Project leach pad
facility with the following assumptions: long-term gold price of
$1,300/oz; assumed total ore process costs of $10.59/t;
metallurgical recovery for gold of 91%, and 24% for silver,
refining and smelting cost of $28.39/oz of gold. Allowance has been
made for the facility location which excludes 260,000 t; this
material must remain in-place, based on the heap material mining
and tailings placement design.

Rounding as required by reporting guidelines may result in
summation differences.

Notes:
-
The Mineral Reserves have an effective date of December 1, 2020.
The Qualified Person for the estimate is Mr. Jeffery Choquette
P.E.
-
Mineral Reserves are reported within the pit designs at a 0.01 opt
gold cut-off grade. Pit designs incorporate the following
considerations: base case gold price of $1,300/oz; pit slope angles
that range from 38–47º; average life-of-mine metallurgical recovery
assumption of 93%; crushing costs of $1.81/t, process cost of
$5.79/t, general and administrative and tax costs of $2.90/t; and
average mining costs of $1.42/t mined.
-
Rounding as required by reporting guidelines may result in
summation differences.
A technical report in support of the Mineral
Resources and Mineral Reserves in this news release, prepared in
accordance with National Instrument 43-101 – Standards of
Disclosure for Mineral Projects (“NI 43-101”)
titled “Mineral Ridge Project, Esmeralda County, Nevada, USA” with
an effective date of December 22, 2020, has been filed on SEDAR
concurrently with the issuance of this news release. Readers are
encouraged to review the final technical report in its
entirety.
Data Verification
Data verification performed in support of the
Mineral Resource and Mineral Reserve estimates for Mineral Ridge
included in the technical report prepared for Titan included site
visits; review of QA/QC data, sampling analytical data and programs
from Scorpio Gold and predecessor company drill campaigns; database
verification; review of metallurgical data and metallurgical
recovery assumptions including leach pad performance; review of
mine and recovery plan assumptions; and review of commodity price,
capital and operating cost assumptions.
Drilling performed by Scorpio Gold primarily in
the period 2014–2017 supports the Mineral Resource and Mineral
Reserve estimates. Scorpio Gold employed a QA/QC program of
certified reference materials (CRMs), blanks, and field duplicates
inserted in the sample stream at the rate of approximately one
control for every 20 samples. The same QA/QC program was generally
employed for all samples submitted to each laboratory and the
Scorpio Gold on-site assay laboratory. QA/QC procedures implemented
during the 2014–2017 drill programs are generally acceptable to
support the analytical precision and repeatability. The nature,
extent, and results of the sample preparation, security, and
analytical procedures, and the quality control procedures employed,
and quality assurance actions taken by Scorpio Gold provide
acceptable confidence in the drill hole data collection and
processing to support Mineral Resource and Mineral Reserve
estimation, and mine planning. Gold and silver assays can be used
to estimate Mineral Resources and Mineral Reserves for the heap
leach pad. Silver was not routinely assayed for in the remnant area
drill programs. As a result, only gold estimation can currently be
supported for these areas.
Qualified Person
The Qualified Persons who co-authored the
technical report include Mr Todd Wakefield, RM SME, Mr Bruce
Genereaux, RM SME, Mr Jeffrey Choquette, P.E., Mr Brian Arthur, RM
SME, Mr Ian Crundwell, P.Geo., and Mr Kevin Lutes, P.E. The
Qualified Persons supervised the preparation of the information
that forms the basis for this news release.
