You can see from filings new equity investor shares are being transferred from an original large position holder (275M), plenty available to meet the agreement! No increase in share count required.
$AABB The math DOES add up. Though it's actually much easier than that, as there is no math involved.
In the Q report, it shows the "actual market value" of those shares at the time that they were issued.
So look at the chart - or at a table of the price history for AABB, as I've shown below - and you can see that the closing price was .0275 on 11/21/2018. Thus, the issuance table in the Q shows the "Value of shares issued at issuance" on 11/22/2018 to be ".028"... as shown in the snapshot image below.
This is consistent with the Statement of Cash Flows in the Annual Report (for the period ended December 31, 2018), where it shows the $5 million received for the share subscription (share purchase for funding) - as highlighted in the image below.
This is also consistent with the October 24, 2018 press release with the heading: "Asia Metals Inc. Secures $34 Million Joint Venture and Receives $5 Million First Tranche" - also shown below and highlighted.
Simple like that.
The first $5M tranche of the investment from Qiangda Investments & Economics & Co., Ltd. was received on 11/22/2018 and 20,443,586 new restricted shares were issued to Qiangda Investments at a subscription price per share of 5,000,000 / 20,443,586 = $0.2446.
