Pelangio Exploration Commissions a Deep-Penetrating CSEM Survey for the Obuasi and Manfo Projects, Ghana

About this update from Pelangio Exploration Inc.

Toronto, Ontario--(Newsfile Corp. - February 27, 2026) - Pelangio Exploration Inc. (TSXV: PX) (OTC Pink: PGXPF) ("Pelangio" or the "Company") is pleased to announce that a controlled-source electromagnetic ("CSEM") survey has been commissioned for the Obuasi and Manfo projects to be conducted by SEMS Exploration Services of Ghana. CSEM (Controlled Source Electromagnetic Survey) Details Pelangio Exploration has commissioned SEMS Exploration Services of Ghana to conduct CSEM surveys on their Obuasi and Manfo projects to explore for mineral targets at depths up to 1 kilometre or more. Controlled source electromagnetics is an active EM method where an electromagnetic signal is 'injected' into the ground with the response measured at multiple stations in a grid array. The SEMS survey will employ an IRIS Instruments TIP 12000 transmitter powered by a 20kVA generator to create the EM signal with the subsurface response read by two Metronics Magneto-Telluric (MT) grade receiver units working on a 170-meter grid node spacing. The CSEM method is effective at detecting conductive features and mapping resistive bodies at shallow to intermediate depths (up to several km) and could be effective at resolving Obuasi-style mineralization (conductive sulphide ore and resistive gold-bearing quartz lodes) comfortably to a depth of 1 kilometre or more. The Magneto-Telluric (MT) method in comparison, which is a passive EM method, is a much broader frequency survey enabling deep imaging (to tens of kilometres), although at a considerably lower resolution than CSEM can provide and requiring much longer survey times. Pelangio's Obuasi survey will cover the 'Obuasi Targets Area' on the western edge of the property, interpreted to be on strike with the Obuasi Mine's Main Au Trend. See Figure 1. The survey will cover an area of 9.2km² with 295 170-meter spaced stations. AngloGold Ashanti will conduct a parallel CSEM survey extending Pelangio's survey into their mine property with 333 stations over an area of 10.4 km². While SEMS will be conducting the survey over both properties, the surveys are independent of one another and a possible data-sharing agreement has not been discussed. The northernmost known (from public information) orebody on the Main Au Trend at the Obuasi Mine is the 'Far North' ore shoot, also refer...
