5. Full Description of Material Change:

Avanti Energy Inc. (TSX Venture: AVN) (“Avanti” or the “Company”) announced that it has now acquired key 2D seismic data over its recently acquired strategic land package in Alberta (see press release dated May 10, 2021).

The Company has licensed several privately-owned 2D seismic lines and the early interpretation has confirmed the presence of a large structural closure, previously identified by the Avanti team using well data in the area.

Genga Nadaraju, Vice President, Subsurface Geology, commented, “With the seismic data in hand, the team has now moved to complete a detailed evaluation phase to optimally position well locations for the upcoming drilling program.”

Avanti has also initiated the environmental review necessary for the planned Q3/Q4 2021 drilling program.

The ~2,500-acre property is highly prospective for potential helium extraction, residing over an area with a closed structural high that is ideal for trapping helium and multiple helium shows have been identified in and around the property with shows up to 2%. Previously drilled oil and gas wells on the property show high nitrogen content of ~95% in multiple zones. Nitrogen at this concentration is important because it is often associated with producible quantities of helium and the production of helium is a relatively simple process.
