Four ASX shares that are not letting that hold them back are listed below. Here's why they are pushing higher:

Mesoblast limited (ASX: MSB)

The Mesoblast share price is up almost 8% to 84 cents. Investors have been buying this biotech company's shares after it confirmed the submission of substantial new information on clinical and potency assay items to the FDA. This is for items identified by the regulator for its remestemcel-L product in the treatment of children with steroid-refractory acute graft versus host disease.

Unibail-Rodamco-Westfield (ASX: URW)

The Unibail-Rodamco-Westfield share price is up over 4% to $3.20. This has been driven by news that the shopping centre operator has completed the sale of the Villeneuve 2 centre in the Lille region of France to Ceetrus. This means that the company has now completed 3.2 billion euros of disposals, representing 80% of its 4 billion euros European disposal programme.

Widgie Nickel Ltd (ASX: WIN)

The Widgie Nickel share price is up 28% to 30 cents. This follows the announcement of a major lithium discovery from the company's Mt Edwards project. Management commented: "This initial reconnaissance work identifying high grade spodumene over a significant strike length couldn't be a better outcome for Widgie."

Yancoal Australia Ltd (ASX: YAL)

The Yancoal share price is up 2% to $5.78. This morning this coal miner announced that it will make a major debt repayment. Yancoal advised that it intends to prepay US$1.0 billion of debt from available cash on 4 October. This consists of payment toward Yancoal's Syndicated Facility and its unsecured related-party loans. This is expected to deliver an approximate US$207 million reduction in total finance cost over the loan periods.

Why is the Widgie Nickel share price rocketing higher?

Investors have been scrambling to buy the mineral exploration company's shares today following the announcement of a major discovery.

However, unlike what you might expect from the company's name, Widgie Nickel has not found nickel. Rather, it has found high-grade lithium bearing pegmatites at the newly named "Faraday prospect" of its Mt Edwards project.

According to the release, lithium bearing pegmatites outcropping over a 600-metre strike with surface expressions of up to 25 meters wide have been identified at the prospect.

Management believes these early stage exploration results are extremely encouraging and provide the company with the opportunity to significantly increase its lithium exploration activity within the highly prospective tenement package.

Field work is expected to commence immediately to drill test high-priority targets at the Faraday prospect as well as detailed mapping, soil and rock chip sampling across the Widgie tenure.

'Couldn't be a better outcome'

Widgie Nickel's managing director, Steve Norregaard, was very pleased with the news. He said:

This initial reconnaissance work identifying high grade spodumene over a significant strike length couldn't be a better outcome for Widgie. To think we have 170,000t of contained nickel and we now can lay claim to hosting complementary and widespread lithium pegmatites in this world class lithium corridor.

Widgie looks forward with great anticipation to getting a drill rig on this highly prospective target which will only complement the existing drilling effort on our nickel resources.

Widgie Nickel share price rises following IPO

Investors have been bidding the Widgie Nickel share price higher today following the successful completion of its initial public offering (IPO).

That IPO saw the company raise a total of $24 million before costs at an issue price of 20 cents per new share. This gave the company a market capitalisation of $50 million at listing.

Though, with the Widgie Nickel share price rising to 29 cents, its market capitalisation has now ballooned to $72 million.

What is Widgie Nickel?

Widgie Nickel is exploring the Mt Edwards Nickel Project in Kalgoorlie in Western Australia.

According to the company, the Mt Edwards Nickel Project is a unique consolidation of a vast ~240 square kilometre package of highly prospective nickel and new economy metal prospects. It has a large nickel sulphide resource base of 10.2Mt at 1.6% Ni for 162.6kt of contained nickel, in a globally significant nickel district.

In addition, the company notes that the Mt Edwards Nickel Project possesses exploration upside potential to underpin long-term shareholder value creation. It has material exploration campaigns planned for the post listing period.

Widgie Nickel's Managing Director, Steve Norregaard, appears positive on the future.

He commented: "The successful entitlement offer has ideally positioned Widgie to methodically work towards unlocking the significant latent potential the Mt Edwards Nickel Project possesses, which was evidenced by the promising drilling results at Munda we released to the market today."

"Widgie intends to commence an ongoing drilling campaign within the next month to continue to unlock this value," Mr Norregaard concluded.
