Teranga’s Wahgnion exceeds planned production by 25%

Teranga Gold (TSX: TGZ) has provided an updated life of mine (LOM) plan and issued new 2020 guidance for its Wahgnion gold operation in Burkina Faso as a result of the mine achieving higher than planned production.

Since commercial production began in November 2019, Wahgnion’s processing plant has performed approximately 25% above nameplate capacity for throughput and gold recovery, the company said.

Given the increase in planned production, Teranga has updated the LOM plan to accommodate the higher plant throughput capability, increasing Wahgnion’s average annual production by 25% and reducing the mine life to 10 years.

With the goal of extending the mine life to 15 years, Teranga has initiated a multi-year drilling and exploration campaign around three of the existing deposit areas and at more than a dozen promising targets at Wahgnion.

Teranga has also increased Wahgnion’s 2020 output guidance to between 150,000 and 165,000 ounces, up from earlier guidance of 130,000 to 140,000 ounces. The higher guidance for 2020 is based on mill throughput of between 3.0Mtpa and 3.2Mtpa and total material movement of between 22Mtpa and 26Mtpa, the miner said.

“The updated life of mine plan is very good news for Wahgnion, and for Teranga overall,” CEO Richard Young said in a media release.

“With production averaging about 150,000 ounces of gold per year through 2025 at reasonable costs and at current gold prices, we expect to generate significantly more net cash flow from Wahgnion in the coming years, compared to the original feasibility study.”

Shares of Teranga Gold were down 2.8% on the TSX by 1:30 p.m. EDT, capping the Toronto-based gold producer at a market value of C$2.6 billion.

Last week, analysts at Canaccord Genuity raised the stock’s price target to C$19.00 from C$17.50 following release of the company’s Sabodala-Massawa gold complex prefeasibility study, which confirmed the Senegal mine as a “top tier” 

Cone crusher liners are the most important wear parts for cone crusher. The cone crusher liners melting process is the key to get a long time span life. At present, many factories use intermediate frequency furnaces to melt high manganese steel. In order to obtain high-quality cone crusher liners castings production plants, the following points must be done:

(1) The strict control of raw materials, selection of non-rust, oil-free waste steel, suitable ferroalloy materials.
(2) Strictly control the chemical composition, the manganese/carbon ratio should be greater than 10, the carbon content is 0.95% to 1.2%, the silicon content is less than 0.6%, and the phosphorus content is less than 0.045%.
(3) Strictly control the tapping temperature between 1480 ~ 1550 ℃, pouring temperature between 1390 ~ 1430 ℃, ensure grain refinement, grain size should be greater than grade 2, and improve wear resistance of castings.
(4) Refining technology should be used, such as blowing argon at the bottom of the furnace. Blow argon in the bag, add a composite modifier, nano modifier and other methods to deoxidize and degas, remove slag inclusion, and purify molten steel to make nitrogen, hydrogen, oxygen and non-metal slag inclusion extremely low.
(5) Strictly follow the operating procedures for melting high-manganese steel in the intermediate frequency furnace, and carefully and carefully operate each link.
(6) Add external cold iron, suspending agent, internal cold iron, hard alloy column, etc. to refine the grains and improve wear resistance.
