ORETERRA READY TO DRILL AT TREK SOUTH COPPER-GOLD PROSPECT, GOLDEN TRIANGLE, BC - CONTRACTORS IN PLACE FOR MAIDEN PROGRAM

All contractors have been secured for Oreterra Metals Corp.'s fully financed, maiden Trek South drill program, which is targeted to get under way in mid-July with two drills. Equity Exploration Consultants Ltd., of Vancouver, is managing the program, which will include geological, geophysical, archaeo-environmental, pad building, helicopter and drilling components carried out from an on-site camp. The Trek South prospect is new to science, having been revealed by ice melt in recent years, and consists of coincident, high-order, large-scale alteration, geochemical and geophysical (induced polarization (IP), magnetotelluric (MT), magnetic) anomalies present within and below more than a square kilometre of exposed bedrock located outboard to the toe of the Trek Glacier, and extending thereunder. It is located in British Columbia's Golden Triangle, adjacent to Teck-Newmont's Galore Creek deposits, presently undergoing prefeasibility studies, and only two kilometres upslope from partially completed infrastructure, including an all-season road and camp.

"Our Trek South field plans have shaped up nicely and the drill start is close," said Kevin Keough, chief executive officer. "It will be an exciting summer as we attempt to deliver a major copper-gold discovery -- two metals that are much in demand in a turbulent, fast-evolving world."

This season's program will follow the recommendations of a National Instrument 43-101 technical report dated Jan. 20, 2026, a copy of which may be found on the company's website and on the company's issuer profile on SEDAR+. The technical report recommends two initial phases of drilling at Trek South, with widely spaced holes appropriate to the porphyry copper-gold-silver target type and the large scale of the prospect.

The phase 1 Trek South drill program as initially planned will encompass approximately 4,650 metres of drilling in eight widely spaced angled core holes targeting the prominent magnetic high and coincident IP chargeability high and resistivity low, present below a large area of intense porphyry-style alteration and values of copper, gold and silver in exposed bedrock. Some adjustment to the number of holes, locations, lengths, dips and azimuths is expected to occur as the rocks tell their story. Subject to the success of phase 1, the recommended second phase of drilling would commence immediately thereafter, expanding the drilled area with step-backs and stepouts encompassing an estimated 4,600 metres of drilling in eight widely space angled core holes.

About Oreterra Metals Corp.

Oreterra Metals commenced trading on Feb. 2, 2026. Management believes the company's wholly owned Trek South porphyry copper-gold prospect represents, based upon the impressive results of the spectrum of geosciences applied to the target area to date, among the finest new targets of its kind in B.C.'s Golden Triangle. The company recently released (news release dated Jan. 22, 2026) a National Instrument 43-101 technical report for the Trek property, which recommends two initial phases of drilling at Trek South, for execution in the approaching 2026 field season. A copy of the technical report is available on the company's website and on the company's issuer profile on SEDAR+.

Additional wholly owned company property interests include two former producers in Nevada: the Kinkaid claims in the Walker Lane trend covering numerous shallow Au-Ag-Cu (gold-silver-copper) workings over what is believed to be one or more porphyry centres (source: J. Biczok, PGeo, June, 2025), and the Scossa mine property in the Sleeper trend, which is a former high-grade gold producer (source: J. Biczok, PGeo, July, 2025). The company also holds a 100-per-cent interest in the large Lundmark-Akow Lake Au-Cu property adjacent to the northwest of the Musselwhite mine in Northwestern Ontario, where drilling by the company has produced highly encouraging, broad VMS-style (volcanogenic massive sulphide) Au-Cu intersections.
